There's also a Hoodoo Brewing Co. in Alaska.
Here is a shot of the raw tweed and the shellac mixture tint I am going with. I will top coat this with lacquer to seal it.
Here is the cabinet before the tint and the grill cloth was not stretched yet.
Here is the tinted cabinet with the grill cloth stretched.
Final of coats of lacquer done.
Now it just needs some light relic work to make the back panels match!
It is not perfect but so far I have spent about $160 on the recover, grill cloth, shellac, lacquer, handle, filter caps, couple of resistors, power switch, feet, grounded cord and a few other things. I switched back to the old handle hardware after this pic. I need a few little nuts and washers to put it all back together. Since the OT is mounted on the speaker I didn't want to start testing voltages with the tubes in until I had the speaker connected to the OT.
Put the logo back on
There's a society for you pro archaeology restorers. Great work!
I powered the amp up today, first without any tubes and then with the rectifier only checking voltages.
Using a light bulb limiter all is good. With the power tubes in the light bulb glows a peachy color brighter than I thought it should but I tried both of my other Pro Amps and they both glow about the same brightness. The amp works and plays with a very slight distortion on notes that are not loud and should be clean. The amp is quiet and there are no strange noises except for a little distortion on notes that should be clean and that could be the speaker.
Pin 4 362 v
Pin 6 362 v
OT center tap is on rectifier pin 8 and the primaries on pin 3 of both of the 6L6 is 290 v on the plates of both tubes
The filter caps B+ voltage 295 v, 295 v, 247 v, 224 v the 3rd and 4th showing the voltage drop from the 10k resistors
Heater voltage on all the tubes is 5.25 v + or - .03
It works !
That looks fantastic. It was sleeping all those years waiting for you to wake it up...
Godzilla did the same thing!
Amazing work man!
I really like how that amp came togethor.
I have a hot rodded 5c5 based amp and regularly play through my buddy's original 5d5. Tweed pro with octal preamp tubes really is a special thing.
