The Amp Garage

I puchased a 5E3 Tweed Deluxe clone built with vintage iron, 12” Jensen, NOS components. The bass - in particular the low E string - resonates. The first thing I did was to swap out the vintage Jensen speaker. No appreciable improvement. I patched the amp into an external speaker cabinet, and the sa...

Here’s the remaining bulb for reference

Got it!

Fairly easy and intuitive. Thanks for the tips.

All large sockets. On closer inspection, I’m finding engraved tube designations on 5 of the 8 sockets. 6JS7 on the 2 closest to L side (one directly behind the other). Moving along the back ‘row’ to the R: 6SN7 6SL7G (schematic shows 6SL7) 6SN7 In front of the 6SN7 and the PT are 3 unmarked sockets,...

Thanks. From one Martin to another…

Looks like the G3.5 shape round bulb is not available for #47. Think this is part of the reason upper panels left off as there’s no clearance beyond the bulbs. Only alternative I can find is a 7 V auto bulb.

Thank you very much! Looks like the tweed upper panel helped bounce the light into the plexi panel a bit. The lone bulb in mine is indeed bayonet type, and I guess I should have surmisedr measured 6.3 VAC (doh!). The bulb itself is round rather than elongated (probably helps position it behind the p...

I have tried the art supplies route and unprimed linen canvas of varying weights/weaves with no luck. Canvas duck in heavier weight seems closest but not quite a match. Will post more re the trial-and-error journey and hopefully any Eureka! moment.

Picked up ‘52 National 1215 tube “project” amp. No tubes were installed in the amp. I have a schematic and could likely figure out what goes where re proximity to other components / pin config, but…if anyone out there has one of these amps and could help with tube layout, this would be greatly appre...

Picked up a nice ‘52 National 1215 amp (Valco made) that has/had tiny light bulbs to backlight the plexi panel over the backpanel controls. I guess I could see what happens via trial and error, but wondered if anyone had any suggestions. Nothing spec’d in schematic; no markings on the remaining bulb...

Does anyone have a link or file re cab plans for a Fender Vibro Champ? Want something I can hand off to a cab maker. Thanks.

Looking for what seems to be unprimed linen or canvas material used to cover a ‘52 National 1215 amp. Back panels missing so trying to make these. Weave is pretty coarse - about 19-20 threads/in. Shellac finish. See pics. So far, striking out with most materials I’ve been able to find. Someone sugge...
