Peavey Backstage Plus - Original Speaker?

Post by Lamf77 » Thu Jan 19, 2023 6:17 pm

Hi. Just snagged a Backstage Plus this afternoon. Could not pass it up for $75 and 7 minutes from my house! Pots are scratchy, bright knob is touchy and reverb is MIA....but everything else sounds sweet. I was just wondering if the speaker in it is the original stock speaker? If so.....anyone know what type? Thanks!

That Peavey part number is correct for that amp. Looks like it was made by Rola.

Reverb tanks can be quite salvageable; the usual problem is a loose connection. The one thing that cannot really be fixed is when it's overgrown with rust that damages electrical or mechanical parts.

The Peavey part number was 71011109. Accutronics, Mod and some others will be numbered 8EB2C1B. You have some options. 2 or 3 spring, medium or long decay.

My Backstage Plus is a rescued chassis that I rebuilt and turned into a head cabinet and separate 12" speaker cab. I put a used Accutronics 8EB2C1B in it. Got it cheap because it was miss marked. If I was buying new I would go with Mod tank. Just my personal preference.

Clean the reverb tank cable and jacks on both ends. Over time they can get pretty corroded. There could be a broken wire on one of the jacks on the tank. But like DAK said, if the springs are rusted up it might me a lost cause.

There is an OPAMP that drives the reverb. You may need to carefully lift it out, clean the legs and socket the re-install it. Be sure to get it back in the same way it came out,

I took out the tank. One of the tiny black wires was loose. Soldered and all good. Thanks!

That's great. I've had reverb problems on several amps over the years but haven't had a tank that wasn't fixable.

I have seen one (not mine) that the springs were so rust that they broke when cleaning was attempted.

No, I'm in Southwest Oklahoma. I grew up in Wichita, Kansas and Old Style was available there but never tried it until I was stationed at Fort Riley, Kansas. I used to drink it a lot but nowdays just every so often. I drank Heileman's Special Export daily until we couldn't get in this part of the country any more. Like Peavey amps and guitars, I like the old school beers. Love them for what they are, not what you want them to be!
