Gentlemen,
It has been a while since I check in with you. It has been a great summer here in
Today I opened up a Grundig 88U. Three tube AM/FM radio. The American version I believe. It has an interlocking power cord (cheater cord) and American words on the back cover. My question is two fold.
1) It the iron core object an auto transformer, choke or a power transformer with a primary and isolated secondary? In the European model it is an auto transformer. This makes the radio a hot chassis unit.
2) Is there an American alignment document available? I tried to locate an “88U” but no success.
I will be restoring this radio once I come back from the Kutztown PA swap meet. I see several paper/wax capacitors that look questionable. The radio plays but poorly on FM. All the FM stations are fuzzy and distorted.
There are some light blemishes and minor scratches on the red plastic. I will be using the Novice polish #1, 2 and possibly 3 to restore the original mirror like finish.
Thanks,
Paul P.
