I have a old homemade amplifer with a QB4-1100 tube from Philips.
The problem is that the meter blowed off and wires out of the transformator was
bad condition.and the tank caps was leaking.
I changed all the components, like the meter and diode/resistors and capacitor
I think I maybe have changed the polarity out from the transformator for the
coz when I key down the amp, the meter goes up as normal, but the tube isnt
so only thing I think can be the problem can I did something wrong about my new
wiring from the grid transformator.
the tube is ligthning normally.
