Ok I have ordered a new 35A5 tube . Meanwhile I measured the heater voltages on all the tubes.
Here are the results: on all the "7 tubes" I got 5.3 volts. On the 35Z3 I got 32 v, on the 50A5 I got 45 v .
Does this mean that the circuit has been modified to provide more voltage for the 50A5 or does it just naturally have more voltage on it by virtue of the tube structure, in other words it demands more so it gets more voltage.?? thanks
