Simon,
I always keep my junked electronics for parts, or if I don't have the
heart to part it out, I sell it on Ebay. :)
I took it apart today. Luckily, I was able to fix the CD player simply
by cleaning the lens real good. I did the same to the MD recorder, hope
that fixes it. I discovered the XR-H66MD is fairly new, since it uses a
CXD2652AR ATRAC chip which is at least ATRAC 4. All calibration
parameters are also stored in EEPROM, so all adjustments will have to be
performed via a secret service mode. Anyone happen to know what the
procedure is? If it still skips during recording, I believe the problem
could easily be corrected by increasing recording laser power just a
little bit. AFAIK, it doesn't skip at all during playback (of discs
recorded on other recorders).
