Reimyo CDP-777 service manual

[Rainer Weber]

Dear all,

I would like to tweak my Reimyo CDP-777.
My ideas were to modifiy clock and power supplies.

For that purpose a service manual would help a lot.

If anyone has the information about the clock and voltage regulators, I would highly appreciate if he could share this.

Best regards

Rainer

JVC "EXU-901a" (KRELL KPS-25sc Phase Tech CT-1 CT1) better than VAM1254, CDpro2LF ?

JVC cd mechanism "EXU-901a" (KRELL KPS-25sc Phase Tech CT-1 (CT1) - better than VAM1254 (CD-pro2M + CDpro2LF) ?

Who know more about the JVC cd transport mechanism "EXU901a" (EXU901 EXU-901).
I don't find datasheets, information about optical pick up (laser unit) and order sources for spare parts so as the complete JVC device.
I know about only two cd player brands, where this mechanism is inside:
1) Krell KPS25SC
2) Phase Tech CT-1

After ask combak.net regarding companies for repair and part service for CDP-777, I get this reply:
Dear Mr. Kirschner, CDP-777 had been sold out long time ago.
Actually CDP-777 is very old model. Therefore we did not have any information
COMBAK
Maybe someone here knows which companies currently offer a service for parts, repair and maintenance for this model.
Thank you very much.

according Vasiltech CD Pro 2M (VAU 1254/31), which is according Vasiltech also in use in the CDT-777
Are there CDT-777 (transport only) variants from first series, where is in use JVC's EXU-901a ?
