Hi,

I would like to build a simple but good MPX to Stereo FM adaptor. With solid state or tube power supply, no problem. I have popular tubes in stock, so maybe if you have a schematic with tubes easy to find today, it could be interesting for me.

Thanks for your help!!

Hi,
Online, you can find a schematic, and the specific information on the tubes used to evaluate for a substitution here:
http://208.190.133.201/tubes/rca25/small/index.html
This manual had in the applications section just what you seek in the form of Vacuum tube circuits. For solid state, GE transistor manuals do have some of those circuits for a solid state version.
