Toshiba XR-9219

Hi folks


Does anyone have the service manual for this CDP?

I bought one of these in fully working condition for just 10ukp, it looks to be a well built unit with plenty of space inside for upgrades.


DAC: Toshiba TC9219F 1-bit
Mechanism: SONY KSS-150A / KSS-210A

I bought this player in order to practice upgrading - I already have a pile of parts to use, so just needed a suitable player to work on.

I figured these upgrades would make a worthwhile 'phase 1':

• Replacement of transformer with dual output torroidal.
• Replacement of PSU circuitry with discrete capacitance multiplier type
• Addition of secondary PSU running off second winding of transformer
• Clock upgrade using Chinese circuit board I already have, running off secondary PSU
• Replacement of electrolytics in signal path with polypropylene, possibly replace resistors in signal path if they are carbon types.

Then as phase II:

• bypass onboard DAC and install upsampler and DAC boards (already have these)
• install analogue output stage (buffer)

Thoughts, comments?
