Anyone know a test for the circuit board?
Remove the circuit board and examine the solder joints very closely under magnification. Look for a crack in the solder itself, or a minute crack or blackend line between component lead and solder. Anything remotely suspicious, just touch it up with a soldering iron and a tab bit of flux and maybe a tad bit of extra solder.
It is remarkable how many different electronic items I trouble-shooted just that way, most recently our son's old garage door opener, working perfectly again.
Our 1970's GTE 2300 receiver was my best repair. The "Balance" dial on it was finicky for years but was real bad when we shelved the receiver. Many years later I re-soldered every dial on the receiver which took care of all kinds of things. The unit has since been like new again.
The stereo system has since been in our throw-back rec room. It is entertaining to watch our guests, especially our younger ones check out the 70's setup. They play with the controls and such. They also love to watch our Techniques turn table drop the next album and also play with the laser speed adjust. The speakers are original GTE and are in perfect condition to this very day with great sound quality. Our son creates techno music with a serious sound-creation room in his place. Even he is impressed with the quality of sound from our old 70's system that was not high-end equipment back then.
A quick search on the internet, I found a pic of one like ours.
Sorry to get off-topic.
