Hello
I have just "completed" my first SOHA II and my initial optimism at it working first time has been dashed and I just can't figure out the problem so any help will be much appreciated.
Regarding the test point voltages:
TL+ and TL- are 15V
TB+ is 125V
but TH is only -2.6V not -12.6V.
All the other test point voltages are to spec and the really cuts in and the power LED lights up - all until I install the tubes and nothing happens. They don't light and the power LED fails to light. I assume it's down to the low heater voltage but can't figure out how to get it up to -12.5V
Regards
Steve
