"Paul Hovnanian P.E." <paul@hovnanian.com>: Apr 12 05:59PM -0700 While I am on lockdown, I am fixing a pile of old equipment. The subject dual cassette deck is in need of new belts. I found one set on EBay. But the German vendor replied with "Ve do not ship to ze states!" Another site, https://www.vintage-electronics.net has what appears to be a pretty decent selection of belts (and other parts) for numerous models. But not for this exact deck. My experience has been that manufacturers usually don't re- invent the wheel and it is entirely possible that a belt set (or two) for some other TEAC deck might fit. But my Google-fu fails me at finding any sort of parts cross reference.   Any ideas? -- Paul Hovnanian mailto:Paul@Hovnanian.com ------------------------------------------------------------------ Experience is the worst teacher.

They are made with remarkable precision, and will even replace turntable belts without issues. And it has also been my experience that they have greater longevity than the typical belt - and may be ordered in a variety of materials to enhance even that.   https://www.mcmaster.com/o-rings   Order by sheave dimensions and ID, going about 3-5% smaller on the ID if measuring the physical situation, or exactly if ordering from the manual. How to get a measurement? A bit of string and a marker.   One further remark: NOS belts contemporary with the device are likely no better than what came out of the device. There is no way of knowing whether you are getting fresh stock, or not.   Peter Wieck Melrose Park, PA

You must register, but there is no charge. Now look for the manual for your deck and note the TEAC (Tokyo Electro Acoustic Company - that's today's trivia) part numbers. Now look at similar decks for the same part numbers, or just do a search of the part number.   I often find that companies do series of products, so using your model as an example, I'd look for models with the same letters but 550, 650, 850 etc, or maybe 740,760, 780.   Best of luck in your quest, and hope you find your basement floor! I'm sure mine is under all of that stuff somewhere....   Stay well, Tim

To experiment at data recovery, it sometimes helps to get an adapter (to USB) or external case, like this   <https://www.aliexpress.com/item/32992601773.html>

"Paul Hovnanian P.E." <paul@hovnanian.com>: Apr 12 06:17PM -0700 > another monitoring switch shorts the power feed   I'm looking ata schematic from an old Sharp microwave. There is such a 'monitor switch' which shorts the power supply. It is located immediately across the magnetron primary. So, should al other interlocks and control relays fail, this will indeed blow the fuse.   Now, back to the original rumor. Should someone open the door on the oven rather then wait for the control to shut off power, that short may be applied to the transformer before it and/or the magnetron has bled off energy. The resulting transient might be enough to shorten the life on something.   -- Paul Hovnanian mailto:Paul@Hovnanian.com ------------------------------------------------------------------ Someone figured out my password.
