Philips/ISP IS 5021 sound enhancer info

Hello all,

I've got this I.S.P. IS 5021 "Sound Enhancer" in for service. It's a
stereo digital processor from Philips, though its only marked as being a
Philips product on the rear panel. Anyway, I'm trying to find a
schematic and fuse values for the power supply, and Philips is of no
help at all. Does anyone have any service info on this model? I've got
a sales flyer and owner's handbook, but they do not have the info I
need. (The unit and its external power supply are made in Belgium, if
that's of any help.)

Regards,

I have one --- power supply went dead few years ago --- called Phillips and the tech sent me a new one. This one went (cracked circuit board) and I was going to call this week. Am curious if you got a hold of a power supply.
