Mitsubishi HS-U595 belt sizes & source?
 

I've got several Mitsubishi HS-U595's that I'm reconditioning for a project. They've sat for some years unused but in good environmental conditions. Some are fine/perfect, but some have transports which are very slow to FF/REW (but play fine), and at least a couple have trouble with tape loading or unloading, especially near EOT. I'm guessing that both types of malfunctions are belt issues. I've been unable to locate a service manual for this exact model number, so if anyone happens to know the type (square, I think) and size of belts these units use, I might order a set or two. There's a very expensive eBay source which mentions compatibility but not sizes (and I wouldn't be happy about having to order half a dozen sets at that price). I also see belt kits which might be correct (https://kpcomponents.co/products/mit...elt-kit-vbk168 and https://www.smcelectronics.com/vcrbltsq.htm) that are cheap enough to try. But if someone already knows the exact size & type, I could confirm with vendors before ordering and before I go to the trouble of removing a transport from a unit and trying to get an accurate measurement. Thanks!

If I was you, I'd pull one of each of the "good" belts and either measure diameter or circumference and order a couple test belts from Marvac Electronics around the size you think you need: https://marvac.com. Their ebay store is here: https://www.ebay.com/str/marvacelectronics. Once you know for sure what sizes you want to use, then you can order multiples of those. Most of their belts are measured by the circumference and the thickness they claim is actually accurate, unlike a lot of the universal belt kits. Universal belt kits from places like Amazon could probably work.

If you don't want to hassle with measuring and trying things, I'd go with the KPcomponents kit, though not sure what international shipping is like since I believe they are out of Canada.

Thanks; I hadn't heard of Marvac before & will definitely check them out, and they look cheaper than the other eBay seller I'd found. And yes, I hadn't noticed that KPComponents was in Canada; that might pose a particular problem at the moment. If I don't hear from anyone that this model is "just like model X" where I can find X's service manual, yes, my next step is definitely to disassemble one and measure; was just hoping to save a step.
