Philco model 511
#6

codefox1 Wrote:A little known fact is that if half of the secondary winding is open, it is possible that the set might be run again with a set of voltage doubling diodes if the remaining winding is sufficient. Of course if it is more than a few shorted windings this may not be possible. Best test is to run the set with no rectifier and see what it does, get hot, crap out (blow the fuse that yopu should have installed,) or whatever.

So take out the tubes, fire it up, and see what you can see.

You mentioned voltage doubling diodes. Where would you install them?
And what are the type of doubling diodes should I use?
What are the part numbers of the doubling diodes?
Thank you for responding.
