Removing power stage from a Peavey amp head - can it be done?


Recommended Posts

I currently run a TE Elf head out from the DI into the FX return of a Peavey Tour 700 for more stage volume. Speakon cables go out to two 8ohm TE cabs from the Peavey. 

I find the Peavey preamp redundant and not what I'm looking for. 

Can the Peavey be chopped up so I can take out the power amp and possibly load it into separate casing to save on size/weight?

Any advice?

So are you just using the Elf as a pre amp then or is it running it's own speaker?

 

The thing is that the weight in the Peavey comes mainly from the power supply with the case probably second, just removing the pre-amp would only save a few hundred grams and a new case would save not much more. The case probably contributes to cooling too so I'm not sure this is a great idea. Other options would be to sell the Peavey and buy a PA amp with the money, class D if you really want lightweight. Alternatively the Peavey has just about the most flexible eq out there. As it happens we measured the response of the Elf, it's a smiley face eq with the midrange suckout centred on 400Hz and with a bit of drive at high levels plus some HPF. you ought to be able to dial up something similar with the Peavey.

Many thanks for your answers. If I'm not going to gain anything from getting the screwdrivers out then I can kind of live with the added bulk and weight.

I don't know the age of the Peavey as I got it second hand but it probably just needs a service. I linked these up as I've got the Trace sound in my head, but I just needed more volume up against the 30+ strong choir I play with. 

 

I could also swap the Elf for a pre amp pedal when I choose which one to get.

I've never owned on of those Peavey's but I've played through a friends. I thought it was pretty wonderful and looked out for a used one for a while. I'm really keen on a graphic particularly when playing in an acoustically difficult space.

I got a great deal on the Peavey - £90 inc ABS case. The guy just wanted to get rid. Everything seems ok apart from a couple of crackles with the pots and sliders and it seems to drive my speakers a bit. Maybe I'm doing something wrong and need to fiddle about, but once I put the TE through the FX return, it's super clean, no problems and very loud.

+1, twelve total bands of EQ beats three bands of EQ every time. One just has to know how to use it. The ELF EQ centers are at 80 Hz, 400 Hz and 4.2 kHz, so approximating the same tone with the Peavey wouldn't be all that difficult.

I don't know. I think a well chosen 3 band can be more musical. I've played through those Peavey heads before and I've not found a tone I like. I settled on something eventually, but I wasn't happy. I've got a degree in Audio and Music Technology - I've got a good idea on the EQ. This amp just had an inherent tone I couldn't dial out that wasn't for me.

Duplicating high and low frequency shelving and midrange bandpass EQ with graphic isn't exactly intuitive, but if you know how they differ it's not all that difficult. However I'd venture that for the average player Q is just a character on Star Trek Next Generation. ☺️

At risk of continuing a thread hijack - despite being a TE lover and of course these are famous for their graphics EQs, there is a reason most amps have parametric equalisation. I have to admit I keep the graphic EQ off most of the time on the TEs unless there is a specific frequency I want to notch out. Instead I mainly adjust EQ through a parametric DI/preamp on my pedal board. Empress explains the difference quite well in this article: https://empresseffects.com/blogs/empress-blog/graphic-eq-vs-parametric-eq-the-guitarist-s-guide-to-equalizer-types

Just as a point you do know that the Elf is made by Peavey?

 

As for advice a simple DON'T is the best I can offer. :)

Yeh I do! Can't seem to get a decent tone I like out of the old workshorse so I might stick with this set up. Lots of faffing around it seems.
