    Music Hall MMf5 motor noise

    Looking at the bearing with the big eyes it its white ball . I agree I think the stepped feel is normal . There were some marks on the shaft that came with 1000/3000 grid spinning in my drill press. The motor bushing must be bad. I will mostly just buy a new motor and belt . I give one more...

    Music Hall MMf5 motor noise

    I think the shaft (pulley side) has flat spots on it . With the motor in half's if I back out the shaft it spins smoothly all the way in it fells like step audio pot.

    when motor starts getting warm (no belt connected) the noise starts also. The hotter the motor gets the louder the noise.

    Music Hall MMf5 motor noise

    The bearing is oiled and uses a white plastic-looking disc at the bottom to support the spindle. It is the original belt maybe that is dragging . The speed was never an issue so I haven't replaced. I'm going to run the motor with no belt .

    Music Hall MMf5 motor noise

    The super lube didn't last the noise is back . The TT ran quite with no record when testing 3 for four times this week. After playing one LP the noise is back and the noise is there with or without a record on the platter or the belt connected .The motor is hot but I can touch it. When the...

    Music Hall MMf5 motor noise

    I didn't use the old grease it looked ok but had a waxy stickie feel to it . I went with Super Lube in motor and some capstan lube I have for a Revox B215 for the main bearing. The manual suggested Mobil 1 or any synthetic with Teflon for the mail bearing, I think capstan lube fits the bill. The...

    Music Hall MMf5 motor noise

    I was able to take the motor apart . I was thinking just redistributing the original lube paste ,its not dry up and there's plenty of it, clean too. The bushings appear to be brass, not bronze anyway. All I have is super lube and light weight turbine oil which will probably run out. I can...

    Music Hall MMf5 motor noise

    I can hear the motor running on my MH turntable and there is scorching on the motor shaft. I am the original owner and didn't play it to death ,I have other TT's. The motor is still playing at the right speed . Does the motor shaft scorching indicate that the oil impregnated bushing has dry out...

    Flattening a warped record.

    I have the Record PI record flattener, it works . I liked their logic on flattening records and like gadgets so I bought one. It all depends on how "bad" the warped is. To many variables to get into it here. They do mention that household ovens do not maintain a consistent temp at low levels...

    dbx Service manuals

    I'm still looking for the SM or schematics for the dbx BX2 (Audio Dynamics B-200) and the dbx CX1. I'm going to have to recap these without them as I'm not getting any younger . There doesn't seem to be any DC offset adjust on the BX2 ,just the idle current ?

    I've been getting a lot of PLN's from Digi-key. This hobby seems to have changed quick in fast 18 or so years I've been in it.

    Capstan shaft thrust movement

    I think the flywheel set by that notch is what they did. The oil impregnated washer must have dried out.

    Capstan shaft thrust movement

    I was able to remove the burr no problem. That washer mics at 0.008" thick. I think setting the flywheel using the notch on capstan shaft is all I can do. You can adjust it some for more or less play but its minimal. I agree there should be some play to prevent binding. Teac assembly must have...

    Capstan shaft thrust movement

    With the flywheel installed it would be hard to measure for the 0.01". The only adjustment is to move the flywheel on shaft (there is a notched spot in it). There is no back thrust adjustment just a pad. The other picture is of the flywheel and washer. There is burr around the edges of the...

    Capstan shaft thrust movement

    The SM for the A-4300 states 0.01" between flywheel and capstan assembly, which must be the thickness of the washer that is there. There is no thrust end adjustment. Thanks J!m

    Capstan shaft thrust movement

    Is there rule of thumb for how much back-and-forth movement of the capstan shaft. I'm working on Teac A 4300 (R2R). Thanks

    MJ21195G vs MJ15025

    21195/96 are dedicated audio, that's what I was looking for. On the 21195/96 spec sheet its listed Total Harmonic Distortion Characterized but that is not on 15024/25 spec sheet. Both can be used for audio. I wasn't clear, I get the complement aspect. Thanks
