Hi everyone, I'm trying to find a good power amp for my Hellborg pre. I'm guessing the default answer would be the matching power section(s) but I need a more cost efficient soultion. Besides, I need more than 500w. I'm looking at Crown xls 2000 and a few others. Anything against class D power? Suggestions welcome and thanks in advance.
 
Check the input sensitivity on those. I had a similar model and it was 1.4V input, and I couldn't get enough signal going into the PA from the pre to get a good sound. Of course, I wasn't using a Hellborg pre, so....
 
Ever tried the SWR 750 Power? It's the only thing that comes to my mind when thinking power head and over 500w.

Personally, I don't see myself going beyond 500w, and I've eyed the 400w amplite of SWR a few times... thinking, that would work well with my VT Bass Deluxe. :d

Yeah, turns out to be alittle more complicated than I thought it would be. I'll probably end up taking the pre with me to the store and try it through a few amps.

Thanks, I'll look into SWR. I'm still green when it comes to putting pre and amp together. I probably won't use all 500w, I just don't want the amp to strain while giving me 400w.
 
Actually, the Thunderfunk pushes 750 on it's own but the output really drops when I try to use it to power the Hellborg through the effects return that disables the pre and volume. It has 2. 1 before the pre and one after. Truth is, they are so good that it almost doesn't make sense to have both in the same rack.
 
I think most power heads are made without effects loop, because aren't preamps suppose to have that? I mean, I don't see many power heads around as much as there are preamps. I've noticed only from looking at the Hellborg, SWR, and Tech 21 Power heads.
 
I use a Glockenklang Heart Rock Poweramp with 1000W on 2,7 ohms, 750 on 4 ohms

this gives you all the power you will ever need:-)

but have you thought about a regular PA Poweramp?

You're right, its just that I never intended to use the TFunk as a power section. Its natural headroom is plenty. This is my first separate pre, power attempt.

I'm out shopping for one now. Turns out, they are not all created equally. I almost got one last night but I'm glad I didn't because when I looked it up later, turns out 1 channel was for sub and low signals and the other was for higher frequencies. I'm doing research but don't want to make it an obsession. I had good results today running the HB through my Ampeg V4's power amp in. I got fat, clear tone immediately and really good tube grit at volume, but would only use this as an occasional option. I'm not sure if class D would alter the tone at all or if transformer based power is the way to go. Does it matter? I may just pick one up and try it, as long as its returnable. I simply want to amplify the HB with nothing but volume from whatever power section I choose.

class D might get a little thin on Low B. I own a Markbass F1 which does a good job but nothing compared to
to the Headroom of the Glockenklang:-)

That's what I mean. By the time I find a good amp, pa or bass with enough clean headroom, I'll be spending close to HB power section money. I really like the way it sounds through the V4 but would rather not carry that around! Sounds thin through my portabass head though. I was up practicing till 2am, couldn't put the bass down playing through the V4.
Class H like QSC might be worth a shot. I'll take the pre and my bass to the store and try it out. Only thing is, they always have those hooked up to pa speakers but I should be able to get an idea if I'm On the right track.
 
Found some good info on line and from you guys. Turns out power class, tubes in the power section and context regarding useage all play a part. I've decided to go with a power section made for bass preamps. The dealer I got the TFunk amp from, has agreed to take it back (needs repair) and send me an Eden WT 1250 power amp he just happens to have. Call me old school but I like what transformers do. Might even be a tube in there I think. I'll deal with the weight. Hellborg and Eden? We'll see in a week.
 
Well, the band would be taking a break as soon as I get gear to test:evil: All good though, I got a call for a classic rock band...whatever that means. Hope it works out. Anyway, I had the opportunity to try the HB pre with several different amps and power sections and I must say, I'm learning a lot.(I think) Feel free to chime in;)
Through most solid state heads (with pre's) the Hellborg changes things up a bit and is an upgrade to default tone in regards to clarity. Not "brightness" but real clarity. The only "problem" is that it will still use the head's output circuitry and damping factor. I'm guessing this is why some are underwhelmed when going into the return loop of their current amp. So, the head being used is still controlling the speaker movement.
If you have a really good head like a Thunderfunk, Epifani or a few others I've tried, you could be left with a take it or leave it impression and might as well keep your great amp separate. If you have to constantly switch back and forth and really listen for a difference, I wouldn't call that a big improvement.
Through a Crown XLS power amp, well.....it was loud and clear but the sound was a little thin to my ear. Almost like a dimension of sound was missing or something. I wasn't "feeling" the notes the right way. Mind you, most of my testing was done either in store or at home except for the Thunderfunk and a solid state Ampeg head.
Through the 70's Ampeg V4? :eek::d I wish they had an emoticon for "orgasmic response"! The sound is huge with all of the clarity and no clangy or brittle sound at all. Most noticeable difference is in the midrange response. It is so "vocal" and woody, with the most awesome and musical (useful) break up when you dig in. Not the usual honk that just gets louder if turned up. Not sure if it's the tubes or the transformers in the V4 but, Damn! The most interesting part for me was the fact that the V4 is only rated at 120W or so, but it easily drives a 500W Berg 2x10 and 2 Aggie 112's strung together. All 8ohm cabs. Actually, the V4 is awesome on it's own since I got a tube and cap job, but with the HB in front of it, I get a real old school tone that I've been looking for and I get it instantly. No need to even turn on the pre's eq and the bass is flat. When I do tweak the eq, it makes me think in terms of more or less "voice" and "growl" instead of midrange and treble. Bass, I now call "hugeness".
Through the Eden WT1250 power amp. For me, this is the perfect blend of old school and modern tone. I wasn't sure how I would feel about my clean preamp signal going through a tone pot, but almost right away I knew it would not be an issue. My speakers never sounded so good. Even the HLF is so clear and smooth now. It used to be a simple blunt instrument to me. I now know the difference between 500w loud and 500w clear while making a room breathe. I don't think there's a tube in there but I did see 2 huge toroidal transformers. It's a dual channel amp with a tone and volume knob for each amp. I found this very useful when mix matching cabs. I can run 1 side at 500W at 4ohms while the other (in stereo) accomodates my 8, 4 or 2 ohm cab(s). It's also bridgeable for 1 massive 1200w channel. The tone knob lets me boost or cut highs or lows to either side independently, depending on the room or cab. It has a good damping factor as well. >100 at 8ohms. Pa amps usually have a much higher damping factor which provides tighter bass when used with PA speakers but if you use bass speakers, the higher damping factor prevents the speaker from moving in the way it was designed and will move less air. You'll get loud but your pants leg won't be flapping.
Remember, some of the old tube heads had adjustable damping, so, if your sealed 8x10 cab sounded muddy, you could switch the damping factor and clean it right up.
The HB pre and Eden power section is MY idea of great tone. Through this or the V4, I have found my ideal tone and truely feel no G.A.S. Can't wait to gig the new set and see how it holds up!
Oh yeah, you don't need to spend a ton of money to get great tone, but in my case, it's clear where the money went. I practice ALL the time now just because I like what I hear.

Thanks Gerry :-) So in your experience no PA kind power amp works the same as a real bass head when using only the final section?

I have only tried one. I'm sure there are people here more experienced than me that are using them with good results. I'm just learning about amps really. This is for the people totally in the dark about the subject and may be considering any kind of Pa amp just because of the advertised wattage and weight.
 
People (that are not weight sensitive) swear by the Crest CA9 as power amp for bass rig.
That thing weight even a little more than the Hellborg 500w.

Gerry, have you ever tried just an Eden head, like a WT800?
If so do you think it's the Eden voicing that you like in that WT1250?
There are two 12ax tube in the WT1250.

The Crown you've tested may have a HPF that you can disable to bring back the sub sonic.

Hey thanks. Like I said, I'm sure there are pa amps that get it done. It's just that I was looking for one that had specs (signal to noise, damping) like a bass amp, so I might as well just get a bass amp after factoring in cost and weight.
I checked a lot of forum signatures and researched some brands and models.
The only thing that put me off of the Crest, was the damping factor being a bit high for my taste. Some people like a tight low end but I like the way low damping makes the speaker move. It really fills the room while moving through you.
Just to be clear, the complete Hellborg system is what made my jaw drop, so I know first hand that the best thing I could match it with is the HB power section. It really does make a difference, even though the pre is the "magic" piece in the chain. Playing through my V4 is the closest to the HB power section that I've come. The Eden head happened because I had to try the Thunderfunk amp but kept it too long to return it for a refund, even though it was defective. Since I had money tied up in the store and still needed an amp, I scrolled the inventory and grabbed the WT1250. Fortunately, when I got it I was impressed. I compared it to the V4 through the same speakers and the difference was the sound was a bit warmer and bigger through the Eden but still very clear. I remember reading about a tube in the tone section of the power amp but didn't see anything about it in the manual. It does say the 1205 amp has them so I thought maybe I confused the two. Either way, I was planning how to bypass the tone circuit in case I didn't like what it was doing, but when left flat, it's very much what you put into it. The tone knob doesn't really act like a true (muddy) tone knob but boosts the bass at 46hz when you turn it a bit left while slightly cutting treble and the opposite when turned right. More like a quick speaker adjustment to an over damped, flat room or a very boomy one. I remember reading in the HB tour reviews, a few cases where there were issues dialing in some difficult rooms and the user felt his amp was better suited to cut through.
I know that what I'm hearing is not 100% clean Hellborg tone according to my own "logic":confused:, since the Eden kisses my tone on the way out, but after playing through the comlpete HB system a few times, I know I'm still hearing the true voice of my bass now. One day, I'll have the matching power section but I think I'll be keeping the Eden for quite some time anyway as I find it WAY better than going through the effects loop of some heads I've tried.
BTW, I have not played a WT800 in years. I do remember it being aggressive, clear and warm but I didn't like the enhance knob.
See what happens when you have too much time in between gigs?!? LOL, I'm good for now tho. I'm just anxious to get on stage!
Thanks for the input too. I look forward to learning what I can from you guys here.
 
U have already extreamly high end Warwick Hellborg pre amp, and i am pretty shure that u will ruin it's outstanding sound by using some medicore poweramp.

So i will strickly recommend u to get hellborg powr amp too...

because the life is to short to waist it for crupp

if money are tough u can try a finansial options at ur lockal store but if not then contact Florin, and he will lend u money
Wow! My thread got a Woody response!....You are right though. That is why I am being very careful and doing a little research. Help from here is invaluable. You are my "go to" guys!
I will fill out loan application at Banco Florin!
