Tape Speed and Replacement Belt??
I am trying to use an old, old Toshiba cassette deck
to save some tapes onto CDs. The drive belt is gone, shot, mush, gooey masses of crud, and I have been unable to find a replacement belt. Even the local audio repair shop will not take my dinero. I have found a rubber O ring that fits tightly, but with very little flex. Seems to drive without slipping, but the tapes sound just a tad slow, kinda draggy (played thru the sound card). Probably it's because I don't have the Official Replacement Belt, but is there a chance it's something else? Is there an adjustment, like a potentiometer on the board, that helps fine-tune the speed? Or is it just a matter of the mechanical aspects of the drive? thanks for any help, chuck |

There are places which stock drive belts. Near me, Direct Electronics in Manor Park (E. London) have a box of belts in a large range of lengths (1mm increments). There'll be somewhere near you, I'm sure. Where are you? |

Tape Speed and Replacement Belt??
Any good electronics parts supplier in your area should have replacement
belts. Sometimes these places get listed in phone books under Parts, or Repair, or Radio equipment, etc. Finding them may be harder than finding the belt. Measuring the maximum length of the belt is trivial. Cut a strip of paper to the width of the belt as determined by the bearings in your unit. Thread the paper through the machine following the required path. Pull the paper tight and mark it. You now need a belt slightly shorter so that installation will place the belt under tension. When you find a supplier of belts, ask for a belt just shorter than your paper strip. I did the same thing for a cassette deck of mine when the belt lost all tension and sagged off the capstans. Be careful when guessing what the correct belt path should be. Without a repair manual on hand, you may guess at an incorrect path which will indicate a belt of the wrong length. You should be able to pick the correct path by making sure that the belt does not rub against any stationary part or itself and that all take-up wheel capstans move in the correct directions with respect to the main tape drive capstan. Be patient, fixing a deck for one or two dollars is always better than buying a new one for hundreds. chuck wrote: I'm in Durham North Carolina USA. I've queried several of the "national" belt suppliers and come up dry. I do not have the original belt to measure -- it's a gooey puddle now. I suppose I can remove and measure the O ring that sorts works? But most of the belt suppliers want me to buy in quantities significantly larger than my needs. At their rate, it will be far smarter just to buy a new deck for a hundred bucks. |

Hmmm. Geez. I must apologize. I guess we have NO "good" electronic
parts suppliers in our area. They all tell me thay have "No Lit" on older Toshiba decks. Guess they are substandard. We'll try better next time. None the less, still looking for USEABLE suggestions. thanx, chuck Robert Gault wrote: Any good electronics parts supplier in your area should have replacement belts.
