Hi, I just picked up Mtr 90 mk II that needs some love, well alot of lov e. I have the service manual pdf but I do not have any schematics. Can someone share? my email [email protected]

Thanks.
 
Thanks Pascal, to start with any and all power supply schematics would be great as my machine has psu issue.

The -40v circuit breaker is missing and the larger 'to transformer' connector on the metal psu box shows scoring and burn marks!

 
Hi,

There is no problem, but as above, let me know what do you need.
The schema are only on paper form, and I need scan each page.

Cheers,
Pascal
 
Hi Pascal

I'm having problems with my vari-speed (when I switch on it's just fixed at 29.70  ips

So perhaps for CB-113 and also lower card #4?  (not sure which card "controls" the clock?)
 
Hi,

Strange symptom ...
Please send me a pm with your address, and I will send asap the schematics.
If you have an extender board, you can check on Capstan card, the reference clock should be 9600 Hz.

Best regards,
Pascal
 
Hi,

Didn't want to make a new thread, as I've been told not to in many circumstances. I need the PSU scheme for the MTR-90 Mk2 if anyone has it. If not, I'll post here upon finding it for archival purposes.
