General description:

Gary Dews (Borderpatrol) has designed the schematic.
I also bought the "iron" from him, except the output transformers, that are torroids from Tommy Hørning in Denmark. The grid chokes fro the driver tubers are Magnequest HiNi Gr16.

Valve configuration are 2 x EZ 80 rectifiers and one GZ37 rectifiers. I am using NOS Mullard

Driver tube 6c45pi. (sovtek)
Output one 300B

All power are choke filtered in LC or LCLC configuration, incl BIAS.

Capacitors are Jensen 4-pole.

The amps are 100% disturbance free and sounds absolutely fantastic.

If you have not heard SET 300B backed with REAL POWER like this, you do not know what 300B can be like.

Now I am just waiting for my Western Electric 300B's
