Thanks for the new audio sample. Are you sure this is linear audio recorded in EP? The high frequency response is way too good for LP or EP, and almost too good for SP. But whatever the format, the...

Teefer, comparing the noise performance of the JVC's HiFi playback to its linear is not really a fair test. The linear should normally be much noisier. Your Pana seems to have reasonable linear...

The silent sample sounds about right to me for non Dolby linear audio, Again without new recording and recapture we don't know exactly the performance of the linear audio of that VCR, It comes down...

. I agree that the main issue for the OP here is the noises the JVC unit appears to be adding to the playback. To test or measure that properly I would ideally use a blank tape. But in the absence...

A tape recorded on a misaligned VCR can exhibit the same behavior, Just because it played okay on a Panasonic doesn't make it a perfect tape, A recording test is part of a proper troubleshooting and...

I'm not convinced any caps are at fault here.

However, just to cover all our bases:

An unfortunate reality of shipping older hardware, that has capacitors, is that temperature and elevation...

I didnt bother to request a fresh recording to the linear track as I feel there is proof enough in the JVC playback null that the cause is azimuth error. Listen to the playback and correlate it to...

That's why I suspected bad capacitors, it sounds like a pulse leakage from neighboring chips that should have been filtered out but it didn't. If the OP can record an audio sample and play it back as...

That's interesting, the extra noise bands and "null" band on the spectrum looks suspiciously similar to what you see in the spectrum I posted in the thread I linked about my XVS20. Maybe there is...
