Will,
I bought my first GS35 trafo in germany from a guy that makes them on
demand. He also delivered a 12,6volt trafo for the heater, a control
board and a diode board along with it. I don´t think that he´s selling
many of those. I made a second version with an old military dump trafo
and a homebrew timing and alarm board. This is easy to build an not so
expensive as some boards I saw on the internet.
My first HV trafo is forsale together with everything needed to built
the complete supply for a gs35b. No response yet, it´s been on the net
for 2 months now.
300 euro´s for a kit is to much I guess ... I paid 450 euro´s

This brings me to a question. How much interest would there be in
pre-built plate supplies? They could either have the plate alone or have
the screen-bias, and heater supply included. This way the builder would
only have to build up the tube deck. I wonder if these would be
sellable?
