Wow.Great catch there Levi.As I found my Toshiba DVR/DVD recorder at the goodwill here in town tonight 09/29/2016 .They had a load of DVD players there and not many VCRs.I think they had a 1990's Hitachi there and a couple of camcorders there which I will go down there and look at them later.

Nice find, Levi! According to my files I've never worked on that particular model number. But, it probably uses the same mechanism as that of other similar models. I just don't have a way to cross it.
There were pre-1985 models that had a little problem with the lube drying up. But, if yours is of that era and is working there is a good chance that the issue was addressed in the past and that it won't cause you any problem. Brian |

Oh, yeah, that's newer than the lube problem era. Now you're into what I call the "Top 4" era: Power supply caps, mode switch, loose P2 and P3 tape guides and the tantelum cap on the back side of the capstan motor. Once those are addressed that machine is one to be reckoned with!
Specifically, cleaning and the proper alignment of P2 and P3 may help your switching problem. What's the FCC ID number on the rear panel? Last edited by Blast; 09-30-2016 at 01:54 PM. |

The FCC ID tag should look like the one in the photo.This is used as a example.

Since we were an authorized JVC service center, I worked on a few of those back in the day. I knew the unit as soon as I saw the model number. May be the hi-fi heads worn out, or a tape path alignment. IF the electronics are OK. This is where an oscilloscope connected to the head amp RF test points for the video and hi-fi would tell you a lot.

Other than that it, everything else is working fine on it. |

Also what if the audio works fine on another tape that's the same vintage? I'm wondering because I tried another all analog VHS Tape from 1988 that when I played it it had no problems playing Hi-Fi Audio without cutting back and forth between Hi-Fi and Linear Stereo audio like the Monty Python tape did. |

One way to test if the hi-fi heads are worn or partially clogged, would be to record and playback. If one or both heads are not working properly recording and playback will bring out the problem. If it does that with solid hi-fi tracking and no audio noise the heads are probably fine. Seen many VCRs in the day that would play back hi-fi on good tapes but would have flutter noise or just not switch to hi-fi at all on self-recordings if the hi-fi heads were too worn. The Monty Python tape could have been recorded a bit out of alignment or head switching point was off, or the tape is damaged, stretched or curled along an edge, don't know and can't tell without looking. |
