Is that the M4, or, M5 chassis?
These sets were suseptable to poor connections in the circuit board. Also, the I F cable from tuner often got poor connections. Usually on gound, circuit board connection, or, rarely, in the cable itself.
These sets tended to be troublesome, so, be careful.
They eat electrolytics, and, flybacks alot.
Bill Cahill Nice looking set, by the way.. Scarce model......
