This radio rocks. I changed the connections on the output transformer and lower the total impedance and have it playing on the one local station that plays classic rock and oldies and it is jamming. If I didn't know better I would swear it was FM.

Just in case anyone else replaces their output transformer with a Hammond 125E use terminals 4 and 6 for the secondary. The impedance is lower than the original because it is 6400 ohms for a 4 ohm speaker but using 3 and 5 is 8800 ohms for a 4 ohm speaker and it didn't sound good at all on 3 and 5. The output tubes seem to be running a little cooler too. I am really impressed with the sound of this radio now Icon_biggrin

Maybe I should hook up an RCA jack so I can hook an FM tuner up too it. I see it has a knock out for one on the back for an RCA jack.
