Ok.
Hers the 1st prototype. Assembled on a piece of wood with nails as terminals.

Unfortunatly if i make it say ECC83 than only a few of the anodes will eb used, which woudl decrease it's power handling capability. I'm using all avalible anodes for mazimum current at the moment.
However, if in the next prototype i want to see how well it works as a preamp. Then i wouldnt need high current, so i could make it say ecc83. That woudl be cool.
The prototype is all valve expet form a ''dirty silicone'' bridge rectifier to provide DC for the VFD heater.
