Here is my latest amp design. It is based on Nik's Layout and has some additional goodies:
1. All SoZo handmade caps (closest to Marshall mustard caps)
2. 10K resistor dropped to 8.2K (slightly more gain)
3. Eliminated treble peaking circuit (better sound at low volume)
4. F&T Cap Cans
5. JJ KT77 Power Tubes and Tung Sol and Electro Harmonix preamp tubes
6. 3 watt resistor and 3 amp diodes in power supply section
7. PTFE Wire
8. CGE Pots
9. Mercury Magnetics transformers and choke
10. All metal film Dale Vishay resistors
11. Fender style pilot light
