Good day, All. I purchased a JVC RS-33 receiver back when they first came out and loved the sound, in addition to the handsome design. The problem with the unit I had was that the speaker protection circuit (I believe) would cause the sound to cut out intermittently. The same relay click that you would hear once powering the unit on, after a brief delay, would be heard prior to each cut out. Sometimes is was also accompanied by some discharge-sounding static. It also seemed like the problem happened more in winter when humidity levels were low (I'm in Detroit).
Fast forward three decades and I decided to purchase a replacement RS-33 through eBay, but this unit has the same problem. Since three time's the charm, I purchased another vintage unit and it also has this issue.
When I originally purchased my first unit, I took it back a few times to have the problem fixed. Both times the technicians said they fixed it, but they didn't.
It appears that this might be a design flaw with this particular model or series of receivers from JVC. I'm thinking that there's a grounding or shielding issue in the output circuit that's the root cause. I have tried all the obvious fixes; made sure there wasn't a stray speaker wire touching an adjacent post, trying different speakers, using contact cleaner on the slider pots for volume etc.
Is anyone familiar with this problem? Any ideas on the cause or a possible fix? I've search the forums and it seems like others have this unit, or one from this series such as the RS-77, that operate without any problems.
Any insight the group can provide would be most appreciated. Thanks in advance.
