Both are AB763 circuits and develop around 80 watts depending on voltages etc. There are several versions of each amp. In terms of "Blackface" they are almost identical from a power section circuitry standpoint. There are differences in the preamp section. Mine is a 1971 Dual Showman Reverb... it's supposed to have the same chassis as the Twin Reverb....I'm no amp specialist, so I rely on what Fender says...if it's 80 amps, fine...that's what it is...it's still a great sounding amp, is LOUD and it's BIG. That's why it lives in my office behind the door. It has casters on the bottom of the speaker box so it's easier to roll around. 2 Quote Link to comment Share on other sites More sharing options...
10PoundLester Posted May 6, 2023 Author Share Posted May 6, 2023 (edited) My restoration project is in full swing today. I have the Tolex going on (new pics at the bottom of my gallery linked above) and I'll be adding more pics and descriptions as I go. I love this stuff - I learn new techniques all the time and that's part of what keeps me going. Learned an excellent technique for trimming and applying the Tolex. If there's any interest I'll write that up. Edited May 6, 2023 by 10PoundLester fix a typo Quote Link to comment Share on other sites More sharing options...

If you're referring to the "Tolex" process there are a lot of great videos on Youtube. My post above was actually referring to the use of a specific tool I made from a piece of aluminum angle stock from Ace Hardware. It's detailed in the album linked above, under the photo of the adhesive can.

I have about 400 or so into the electronics - mainly the speaker (Eminence Cannabis Rex), reverb tank and NOS tubes and then another 200 or so into the materials for the restoration. So all in all not a bad deal for 600 bucks and a little labor. The transformers and choke are stock as are most of the coupling caps. I did change a few caps and resistors that absolutely needed it otherwise the electronics are all stock. This amp sounds fantastic. Quote Link to comment Share on other sites More sharing options...

That would be the amount of power the amp draws from the wall. At 120 volts it will draw a maximum of around 2.5 amps which is 300 watts. Has nothing to do with the output power of the amp.

The output is relative to the bias point and other factors that are not necessarily etched in stone so the usually would just give a value corresponding to the power tube output at a given point.

Because the power tubes your amp can use come in different flavors and can develop anywhere from 19 to 30 watts of power each. Quote Link to comment Share on other sites More sharing options...

I’m curious to know if it’s worth more restored or as it is now? As for me I like Cars that are restored to like new Original condition.. I’d like an Amp like this restored to like new original condition as well… That amp was in pretty rough shape. For a dripedge Fender DR in rough shape, that amp was probably worth half of what it was worth in excellent condition, maybe a hair more. A nice retolexing job like that with the new faceplate and new grillcloth and hardware won't increase its value much - maybe a few hundred bucks. But that's about the only thing you can do. Not sure if the blueline grillcloth is period correct. It's hard or impossible to find the actual stuff they were using then. Quote Link to comment Share on other sites More sharing options...

My Showman had automotive vinyl roof material covering it and '57 Chevy silver seatcover material for grill cloth, (I did it back in the 70's). I sent it off to be completely recovered wit Tolex and correct grill cloth to match the new grill cloth on the speaker box, (the Tolex was good on it). I don't recall who I sent it off to, (actually my luthier sent it). Quote Link to comment Share on other sites More sharing options...

I have an electric stapler and a good staple puller. I usually have to pull and replace maybe six or eight staples as I tension the grillocloth and get it all stapled down and straight. I'll get it roughly right and there will always be a few along each edge that are too tight or loose. I'll have to go around it twice, adjusting staples as I go.

I hit the edges with it then the face. The electric stapler is a must, IMO. I do a few inches in the center of each edge then work my way around. Putting the old drip-edge trim back on was brutal. My stapler wouldn't penetrate it so I had to use cut tacks to hold it on. It's pressed into the cab pretty snug but it didn't quite fit right. Can't tell though and I don't plan on taking the baffle back out again. I'm not interested in selling it so I won't have to point it out to anybody else. 🙂 Edited May 8, 2023 by 10PoundLester 1 Quote Link to comment Share on other sites More sharing options...
