Please help if you can: I need a power transformer for Grunow 6C chassis: 5 Volt, no center tap; 6.3 volt with center tap; 600 volt with center tap. Vertical about 4 X 4 X 5-6 inches. Radio uses #80, #6D6, #6D6, #6A7, #75 and #80. I am in Minnesota

I have bought all my transformers from Gary at www.oldradioparts.com....
You do have to do a little searching in a long but well organized list...being careful to make sure you select the right physical size and mounting type ...then looking for the voltages and current ratings... but you can usualy find the right thing... I always have.
He does have a $20 min order so look for other things you need like tubes and such.
Good luck

A minor thing I'm sure but you dupe the 80 in two posts. Crazy me for asking but I got to do it. You do have a 42 instead of another 80? Also if you post the mtg c to c I might have a suitable transformer.
