Building a 5W tube amp Fender Champ 5f1 model copy

It is a fender 5f1 (tweed) copy with some mods: 

- Solid state rectifier (FRED diodes)
- AA764 power source resistors values
- Standby switch
- One knob traditional tone control
- NFB pot
- Resistive attenuator
- Fat switch
- Master Volume (V 2.0)
- 100nF for the second coupling cap (before the vol pot)
- 6V6 United Electron and 12AX7 Tung-Sol
- PIO capacitors (V 2.0)

* I have tried Carbon Comp Resistor as a plate resistor, but the amp has showed up a little hiss noise. So I m still using metal film resitors all around.
