JVC HM-HDS1U TBC Question

[Xhumeka]

Is the TBC circuitry basically the same on all JVC VCR models, or do some units' TBC capabilities perform better than others?

An HM-HDS1U VCR is available locally and I'm considering "adding it to the stable" since the documentation states it has TBC, but it's not listed on the defacto buyer's guide by lordsmurf : https://www.digitalfaq.com/forum/video-restore/1567-vcr-buying-guide.html

Is there a reason this unit isn't listed as a recommended unit, or was it just overlooked because it isn't very common?

Any feedback from those with first hand experience with this unit appreciated!

EDIT - I realize now that the reason it didn't appear in my search is because of the U at the end, and in fact, the HM-HDS1 is indeed listed in Lordsmurf's list. I guess my question still stands though - is the TBC the same on all JVC VCRs?

Not on all of them. Though, most of the JVC SVHS consumer vcrs released outside japan have a similar TBC implementation. The TBC in the DVHS decks (which may or may not be in this one too as it seems it can be active together with the video stabilizer according to the manual) are claimed to be different according to the guide at least (can't confirm or deny). For other ones, the W-VHS decks and the PAL SR-388E together with some japan only SVHS models have an older TBC variant which does stabilization on the chroma signal before upconverting (labelled 629TBC), how well it works I have no idea. The later TBC implementations don't do this afaik. The TBC on the late JVC camcorders is also completely different to the one in the SVHS decks.

Ok, good to know. Thanks for the info @oln!
