    Moving a US Pioneer PL-A35 to Europe – Hunting for a 50Hz Pulley

    Hi everyone, I am sending my old beloved Pioneer PL-A35 to a friend in Europe. Fortunately, my deck features the built-in multi-voltage transformer (100V-240V selector), so adapting to European voltage is already covered. However, it currently has the native US 60Hz motor pulley installed...

    Help! Pinch roller not moving to engage capstan.

    I just recently got a Sony CMT-NE3 CD player and cassette player. When it first arrived, the pinch roller component was detached and I tried putting it back in. When I tried playing a tape, the playback speed was probably twice as fast as it should've been. It did not move up to engage the...

    No Power to Teac X-7 / X10 Capstan

    I have a Teac x-7 that fast forwards and rewinds with no problem. When I hit play, the rollers engage, but the capstan motor will not turn. I have checked the voltage to the capstan motor and it reads 0 volts. When I connect the capstan to 9v directly (via the PCB) it turns and the reels move...

    Nakamichi 500 Pause Stops Take-up Hub, but not Capstan?

    I am refurbishing my old Nakamichi 500. In the process of recapping boards I noticed that at some point the pause does not work. When in Play and I press Pause, the take up reel stops turning but the capstan and pinch roller continue to operate so i get a tape spill. There is a microswitch...

    Pioneer CT-737 Mark 2

    Hello. I was wondering if anyone could help me. I have just acquired a CT-737 mk II but the bracket that houses the capstan motor is missing. Would anybody know where I could get one or would anybody have the dimensions so I can make one myself? I also need the AV mounts. Thanks for your help.

    Two R2Rs with play in capstan - how to fix?

    Hi all. I recently acquired two reel-to-reel tape recorders - a Craig 2107 and a Voice of Music Tape-O-Matic 760. Both are small, low-end, but capstan-driven units. Both work, but are suffering from the same issue - they have longitudinal play in the capstan. The Craig's play is massive - on...

    Revox B710 left capstan spinning like crazy!

    Hello all! I was "given" a Revox B710 a couple of years ago and now I want to refurbish it. The problem is: when I put the power on, the left capstan starts spinning REALLY fast! The unit will still rewind and fast forward but as soon as I hit play, the tape gets mangled all around the left...

    Teac 4010s restoration. Need help.

    Hello. I cleaned and lubed my entire deck and reassembled it. I have one problem that I need to correct. The tape plays well in forward play mode, however the tape seems to be driven down nearly 3 mm by the capstan wheel in reverse play mode. Capstan will push the tape up just 1 mm in forward...

    Teac A-3440 with capstan servo fault (found where but not why)

    Hi, I'm stuck trying to find out why the capstan motor on a Teac A-3440 doesn't spin when the safety lever is pulled (as if a tape was loaded). I restored the power supply board (recaped, all silicon diodes replaced). All fuses are good. Capstan motor has 30V going to it. A quick test by...

    RT 909 some tapes do not move

    I restored as good as I can an RT 909, tapes play, and recording work as well. Some tapes however (like an lpr35 from RMG) - despite threaded correctly - make the pinchrollers and capstans clank in normally when pressing play but they do not move. They rest immobile. Using an Maxell 35-180B on...

    Pioneer PL-115D Turntable 60 Hz Capstan / Pulley

    I have a PL-115D that has a 50 Hz capstan. I live in the USA so of course, I need to use a 60 Hz pulley instead. Am I correct to assume that a 60 Hz pulley from most any 1970s Pioneer belt-drive turntable will work properly? Or in other words, are the 60 Hz Pioneer belt-drive pulleys pretty...
