For what it's worth I think you have a simple voltage drop across the contacts. I fixed an M70 by cleaning the contacts, this restored the music search function which I think is the problem. All you need to do is cut a piece of fine grade sand paper 5cm x 5mm and fold in half lengthways so you...

About 20 years ago, I messed with the power switch on an M70, which is similar to the deck switch. It wasn't working right and I tried to "re-curve" that middle leaf. All I know is it sprung apart, bits were flying and the switch became trashed. It's a lesson I learned the hard way, and which...

...Museum of Modern Art. The boomboxes, if loaned, would be treated as fine art and fully insured. The exhibition runs from May 4 - August 18, 2024 and we would need them from April 1, 2024 until the end of August, 2024. Please message me directly if you are interested! Yes, the JVC M70 too.

I don't know how to thank you Norm. You and Eric did an awesome job. I was speechless when the part arrived. Everything packed well and worked fantastic!! The Sanyo was like new out of the box condition and arrived with broken power supply. I was heartbroken! I approached Norm and he said send...

You forgot the JVC M70 it started it all!

Would you happen to know the belt codes for the GE 5268 ? I’ll probably work on mine next.

here is a picture of the switch

...more issues by changing the setting. #2, although it's common for idler wheels to create issues on many boomboxes if they are deteriorated, the M70's don't really seem to have this issue so much. Ignore this for now and address the following first: #3, upon closer inspection of your images...

glad all went well.... i would have taken a better louder box though like an m70 or that jbl you have....you only live once ehh:beer2:

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...
