Anyone know?

Any input is appreciated.

The M70 / M71 doesn't need to be turned on to play cassettes. The cassette mech has it's own power switch so to speak. Your problem seems to be that your belts failed while the cassette deck was switched on. Superduper tried to explain that to you above and in your other thread. The flywheel...

...are two threads of mine from last year about them. Link1, Link 2 Link 2 may actually be the problem with yours. If I remember correctly, the M70 isn't that difficult to work on. If you decide to undertake the repairs just remember to take a lot of pictures (and from different angles) as you...

...drip). I would say that the unit probably needs a general service. That includes deck service, cleaning of all switches and sliders. Most RC-M70/71 types with sliders may also have issues with those controls too internally. That could involve necessitating rebuild of that slider control...

...The humming could be the transformer. Is it a quiet hum or really loud? I have no idea why the player won't stop. I've had and sold both an M70 and M71 but it's been years so it's tough trying to remember the inner workings of them. Be careful with these sliders. Because they're on the top...

My problems to solve are numerous: Amplification does not work The MODE SWITCH switch is out of order, the 4 positions are not present. Mine is tinkered with shunts. I will replace it with another from a JVC RC-M70 The 3 BIPHONIC LEDs are off The VOLUME and BALANCE potentiometers do not work.

Thanks Super-duper, you re right (of course). Figured out as much, they did put resistors / caps etc in for a (good) reason. The 555 I ve got is a "messed with" one, specs are not as service manual says, things have been bridged, and it's particular din on this particular device seems to have a...

...jack but rather become a smartphone input jack. BTW, @H3NK3L you must be looking at different service manuals than I am. I checked the M70 and RC-555 service manuals and the input resistor on line-in is only 27k, and the M80 is like 56k. Not sure where you are getting 1M. The only time...

...saw you schematics - I looked at the wiring diagram (the pcb and the components and where they go on mine) . So far I only had this issue on JVC m70 / JVC RC-555 / JVC M60 / JVC M80 and some other jvc rc-series. Fysically on the PCB they all have resistors (1M value) between input pins. 1...
