Too crazy??

dave	Too crazy?? Anyone out there ever considered a super reverb sized amp with 9 6" speakers,& 9 single-ended el84 amplifiers (only 1 power supply)?

Peter S	Would you want to drive the multiple El-84 amps with an equal number of preamps? Interesting idea..... ps

Brad	Just curious. Why did you choose 9, as opposed to 8, 10, or whatever? Have you been listening to the White Album?

dave	to Brad:3X3 6 inch in speakers should fit nicely in a super reverb box. to Peter: I figured 1 power supply, & a 2 channel switchable preamp laid out like a Fender... Hope that rounds it out a bit /dave

Brian	well-- yes it sounds crazy, but hey that's cool. As a bit of advice you may feel free to ignore, I would build one section first. I have had a hell of a time with my SE EL84 type amp- the distortion is really farty, pretty much no matter what I do. BT

less bass through smaller coupling caps

less plate current on preamp tubes through higher value Rk's.

A bit on the edge of crazy. Do you really want to shell for all those OT's and handwire all those sockets? A good Champ can drive 2 12" speakers easily. Maybe a trio of speakers each to 3 outputs.
Then again, 9 speakers is still hell to wire and keep track of, espescially in terms of polarity issues. You might have hell to go diagnosing a failure in that array.

Why 9 seperate SE output sections in parallel? might be easier to have all the output tubes linked to a common OT. I can't say I can think of anything that would meet the specs necessary offhand, but one custom job would probably be no more than 9 pipsqueak OT's.
