Philco 511 Restoration and Questions
#25

The transformer is a bit better way as it adds volt gain between the detector stage and 1st audio.

Terry,

I am thinking I will go with another transformer.  Is there one available, small enough to sit inside of the old clam shells for aesthetics?  I have never done this before.  What type of unit and ohms rating should I go for from AES?

Thanks for the help
