Hey all, I'm looking for a Tremolo foot switch for a 1960 Rocket.  Let me know if you have one for sale.  Cheers!  Will

Glad to see an  ancient Ampeg section. I have an 835N that near as I can recon is 1960. It has the original trannys, but someone replaced the cans with F&T's and the EL37's were gone. Can't remember what with but that's unimportant to my question. I replaced every other capacitor, every resistor, cleaned every pot, stuck a JBL E140 in it, and replaced the 6SL7's with 6SN7's for more gain. I may have a done something wrong in my rebuild because I can actually talk louder than this amp when it's on 10. When I stick a vintage clean boost in front of it the sound is so sweet I'm tempted to leave it alone. Is there any long term damage, other than tube longevity, to constantly running a hot input signal? My LPB-2 is really hot and overdrives it nice, does that present any danger? Thanks.

Just saw an Ampeg 815 with a 15 inch speaker on Ebay (jan 02 2018). No connection to me.

Hi! Not quite 20 years ago I made an ebay purchase of an Ampeg bass amp. I spent very little time with it then, and it has been in storage and moving from house to house. This evening I rediscovered it under the basement stairs and decided that maybe it was time to take on this project. And now I admit to being a little bit stumped.

This is a 1x15 combo with blue sparkle covering. Except for the back panel, which is an uncovered replacement. Front and back, it looks like this and this.

There is no schematic (however, there is a schematic for the 835N posted on this site, I have discovered), but the tube chart says it's an 835. It's got a pair of EL37s, and there seems to be a bias adjustment pot, so I guess it's fixed bias. Upper and lower chasis are here and here. The "faceplace" is on the back, angled, and can be seen here.

It's got some dings in the cabinet and a missing back panel, so I doubt it is of interest to any collectors. I think I'll recap it and press it into service. Since this is a pre-portaflex model, it seems to be pretty neglected by researchers, and there isn't much I can find on the internet. It does not seem to be mentioned in Hopkins and Moore's book. Any thoughts or insights would be welcome.
