should be 12-24 VDC. Any ground OK we usually grabbed the
main chassis. Resolder the IF link anyways, they just crimped
most of them. Two other UHF problems are: on some cheap GE
U tuners the drive would go. Also on any UHF tuner there are U shaped
grounds along the shaft. We used to pull them, bend them a little
& clean things real good. Then we discovered that a few drops of
WD40 would clean most of them without all the time & risk involved.
