Ron and all,
I can no longer find Ron's excellent procedure for converting a Philco Model 89 from the 36 tube to the 6A7 tube thereby making it a "Super 89". There used to be a tech tip that detailed how to rewind the oscillator coil and everything. Now I can't find it!
Help! Can anyone tell me where it is?
Thanks!
