You could use a crossover network.

Still would like to hear from anyone that has worked on one.

Thanks,JM. Already emailed Peavey. Best amp I've ever owned.

Hi all, Rats chewed up some wires in my series 400 bass head. The one with the distortion, contour, 6 band tone stack. 210 watts, 2 ohm out Anyone have experience working on these? I'd also like to clean the pots, any suggestions?

The Celestion would be good. If you can get 12+12 out of that transformer, should give you 15V. Also look at the tl082 datasheet. There's a good tone control you could replace the tl081.

Where are you at, Joe?

I don't know how to post links. Look up epemag.com. They've got a good practice amp there.

Hi all, I'll try uploading this again. Is this a compressor circuit that is outlined?

Thank you!

Hi all. I'm trying to find the formula for the rectified output of the secondary. Haven't been in electronics for 35 years. So, a 12V secondary gives me 15V? Power supply. Thanks in advance.
P.S. I am reading Teemuk's book.

The Jensens are ceramic mags. C12rl. 25 watt rms, 50 peak.

Thanks again for the response. I really appreciate it. And I'll do nothing unprofessional :tu:
I'll check out the tl072. I was thinking about a '50 myself. The speakers are 50 yrs old, and still crank!

So, a 3 amp transformer is OK?

Thanks JM! I'll be using 12" Jensen(s). See anything on the preamp stage to take out/add for better bass? I have to redraw the board to move the 2030 to a side heat sink. Might want to put that website so others can see it. Let us know how yours goes.

Oops, that's epemag.
