[Hallicrafters] HT-37 selenium rectifier replacement..HELP!!!!

[Jim]

Paul,
It would be useful to obtain a copy of the ARRL Handbook.
This publication contains a wealth of electronics knowledge, including bias 
circuits and explanations.

Subject: [Hallicrafters] HT-37 selenium rectifier replacement..HELP!!!!

Please, can anyone give me detailed info on replacing selenium rectifier in 
my HT-37, with diode. I am a beginner with electronics and having real 
trouble trying to understand the whole bias supply circuit. I don't know 
what value of dropping resistor to use and am confused as to weather the 
resistor should go to the anode or the cathode side of the diode. The whole 
negative voltage bias thing is very confusing. Please help!

Thanks,
Paul
