    My last days before the electronics repair shop closed (24 years ago) No picture? Clean the vcr path & pix comes back $20. no repairs, ya got to wait for it, no you can't leave it' Used a wooden swab stick instead of a finger nail. Big difference from the 1980's $75 to $150. for service. Good video, keep it up...

    41:06 This has the dreaded Samsung Clutch Syndrome. That slow down at the beginning of the tape was excessive. The pendulum gear clutch will die sooner than later. This is the Achilles heel of these Samsung VHS mechanisms.

    Crazy how fast the rewind is on these with the tape still threaded. My Sony SLV-920HF unthreads the tape during high speed rewind until it gets close to the end, then rethreads and slowly rewinds to the leader. Seems that would save some wear on the heads. Also had the bad blue gear and sticky tape guide, but those have been repaired thanks to your videos.

      @@carlsaucke9944 Yes, it's literally crazy how fast it is, because it self-destructs over time. At 41:06 you can see it slows down excessively while the capstan motor is still spinning fast audibly, just not as fast as at the beginning. It has low torque at lower RPM due to the worn out clutch. The clutch gets bypassed at around 41:30, then the tape gains speed again. This is because the clutch disc or the felt is worn out. The bypass arm used to wear out, too, it is plastic, rubs against a fast spinning plastic clutch disk, eventually it wears to the point that the clutch can no longer be switched to rewind mode, it will remain in playback mode during rewind, and the friction will literally melt it. This is the destiny of all these late Samsung and SamSony VCRs.
      The late Funais can fail similarly, and late Panasonics are also somewhat prone to it, but nowhere near as badly as Samsung and Funai. If someone wants to use these for high volume archiving, never use it to fast forward and rewind, only to playback. They have good picture, but the linear audio is quite trash, it's noisy and lacks low and high frequencies (rolls off at around 100Hz and 8kHz in PAL SP speed), late Funais I think have better linear audio, and their picture is not much worse, if at all.
      The best VCRs for archiving are probably the late Panasonics with the Z mechanism. Simple and reliable, both the picture and the linear audio are good. The 3D Noise reduction of their SVHS line can do wonders with noisy recordings, if you don't have time for software noise reduction. It's not just decreased sharpness, like how most other VCRs achieve 'noise reduction', the 3D noise reduction of my NV-HS850 suppresses really quite well both luma and chroma noise without excessively screwing up the sharpness, even on a 720p screen.

      @@12voltvids Yep, it will either stall the head drum right away, or the drum will pull out a meter of tape and wrap it around itself, before it stalls. You don't have to go back to the early '80s, not even to the late '80s, I have some backcoated BASF VHS tapes from 1998 that does this. Interestingly though, some of these don't necessarily need baking to make them playable. Usually if I FF and REW them beforehand in my Orion VCR that I keep for exactly this purpose, because it does not lace up during FF and REW, they will play back fine on other machines, even FF and REW semi-properly in other machines with the tape laced up.
      Unfortunately, here in Europe, a lot of prerecorded movies are on BASF tape, or on German Fuji, which can have similar issues.

      ​@mrnmrn1 BASF tape was the worst tape ever made. It appears that the germans couldn't make half decent tape either. I remember seeing a warning on, if i remember pabasonic vcr in the owners manual cautioning about using Chromium dioxide video tape which BASF was and they proudly printed it on the box. The warning went on to say that chrome tape was abrasive and would cause excessive head wear that would not be covered by warranty. I saw a few machines that were used to record daytime talk and soap operas 6 hours every day and then play them back at night. Heads worn out in 8 months and the upper drum severely worn. It was eaay to spot. First question was what brand of tape. BASF was generally the answer. Domestic tape used colbalt but the germans uaed pure chrome on their tape and exported it to us to wreck our machines.

      @@12voltvids It's not mainly a BASF problem, seems like chrome was not the best idea for video tapes, although there was no alternative solution when they came up with it in the early '70s for the Philips VCR system. Ferro-cobalt alternatives were developed in the late '70s, the Japanese came out with it in around 78. I mean, the picture and audio quality is usually very good on these BASF chrome tapes, they are 'just' sticky. Their audio tapes were very good, although the early 70s to early 80s made ferric ones are prone to dry shedding if they were not stored under laboratory conditions. Their FeCr tapes just fall apart at this point, if the tape gets damaged, all the emulsion peels off in chunks, just the transparent base film remains.
      But their chrome audio tapes are *physically* very stable, not sticky, no shedding, great sound. BUT every chrome audio tape from any manufacturer becomes unrecordable after 25-50 years, depending on storage conditions. The original recording sounds perfect on them, but you can't make a new recording onto them anymore. Really weird phenomenon. I want to test this with some very old chrome video tapes that are physically good (not sticky). Degraded chrome tape sounds dreadful with new recording, I wonder how will they behave with video.

And what would be the benefit of not putting the lead oxide in the glass that they use as X-ray shield in consumer CRTs?
