Greetings All,
I have a DX-100 I'm working on (albeit slowly) getting on the air. I'm
going to make a few modifications to the audio circuit to satisfy my
vanity, change caps and replace the tube rectifiers with solid state. I
know that this will give me a few more volts and stabilize the PS
circuit somewhat.
I have run across the 1N1239 replacement which seems to be the standard
replacement for a long list of tube rectifiers including the 5R4, 5U4,
and 5V4 to name a few. That's handy for me because I can replace my HV
and LV rectifiers with the socketed solution and not cut up the circuit
too badly. At the most, I'll have to resolder a wire on the socket.
Everything will still be nice and clean.
My concerns are simple. What can I expect in the way of problems if I
use these marvelous devices? Since I'll be changing the filter caps
anyway, should I beef them up somewhat? What is the recommended value
to use with the 1N1239. Anything else to expect or look for, namely
inrush current problems?
Thanks to all, I appreciate your comments and suggestions!
73, W5SAW
