Can you chuck me an email over PM later (throwaway fine), I have a copy somewhere, too big to attach here.

Was sourced from a few lads at a diy audio forum, make sure to create a post in the repair section on eevblog if you do any repair/mods, these units are quite rare but still reasonably capable today.  :P

Bought one myself, mine is off needs a new 3.6v battery and caps are bad. I'm going to do a full recap so I OCRed the service manual and copied/corrected the capacitors values into an excel. This might be useful to others as well. Any suggestions or changes on capacitor values are welcome!

Kind regards,
Alexander

Thank you for sharing!!
Are you done with the recap and calibration? What did you use for the 3.6v battery?

I have a VP-7722a, and some of the front panel push switches tend to stick and not function
properly until about 1/2 dozen or more times pressing and releasing.

any ideas on how to  clean/fix these before I attempt it?
Cheers,
