[Hallicrafters] HT-32B

[Langston, Mike]

I'm refurbishing a nice HT-32B. It has the original power transformer
and it checks good. I want to keep it that way. I have searched the
archives and I know this topic has been discussed before but I'm still
uncertain what causes the transformer failures. 

 

1.	I am replacing both rectifier tubes with plug-in solid state
units and will use dropping resistors to obtain correct output voltages.
It seems like I remember some talk about disconnecting the 5V windings
from the tube sockets because they tend to short to the HV windings. Any
knowledge about this?
2.	I am replacing the bias supply selenium rectifier with an
appropriate value diode.
3.	I have replaced all electrolytic and paper capacitors.

 

Any comments, advice or other suggestions regarding modification of the
power supply would be appreciated.

 

 Thanks and 73,
