I guess I should let you know that the out put of this radio works very good
as I can play the Mp3 player hooked up to the volume control and it plays loud and clear.
I am attaching the best schematic I have of this radio so you might be able to tell me which tubes to inject the signal into and where.
With the last instructions I was not quite clear [ LAST If amp ]?????
I know this is pretty basic for most of you guys, , but I have never done this before.
