GS-35B TRIODE

 

Valve and base, I made this base on my lathe.

Home brew valve base and tank coil, You will need to anneal the copper tubing by heating to a red heat, its makes bending the pipe much easyer.

Adjustable tank coil, copied from ARRL Handbook 1993

I Silver plated the tank coil using silver plating solution, 3.5 turns 1/4" copper tubing wound on 1-3/4" form

Silver plating solution purchessed of E-bay for £12
