Tweedle D
Howard Dumble has designed some stuff for the Tweed circuit. This is going to be something like that. Adding reverb.
Plexi size chassis, pots, switches, tube sockets, transformers. With those you can make an amplifier.
And the rest of the stuff, resistors, capacitors, turret board, turrets.
This is what turned out. Some of the components are going to be connected directly to pots and tube sockets.
Schematics diagram.
Layout plan.
After drilling the holes the components are on their places. I put some nice aluminium cans over the blue can capacitors.
Starting to solder the wires.
Power supply side is almost ready.
Wiring done.
And soon is the time to test the amp.
Addnig some mods that can be found from:

Dove tail finger joints.
Reverb tank placed on a shelf in the top of the case.
Fitting the back panel.
Also fitting the front panel.
Corners rounded.
Measuring the tolex.
Looking the back side.
The front side got a cloth over the panel.
