OK?..manual is complet and helpfull... for repairing such a old and rare boombox like JVC PCM it is necessary...
;
Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt

Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial

ERRORS:
RSA 440:
On all four IC's @PC 1298V), pin 15 and 16 locations are interchanged (rnismarked) on the schematic. On two of the pPC 1298V IC's, (channels one and two only), pins 13 and 11 are connected. Q3,Q28,Q53 and 478 are not the 2N4401 transistor as the schematic im lies, they are an M P S A12 (an NPN Darlington). A static test should show a di e junction from Base to Collector, " + " probe on Base. The input IC U2 on the schematic is labeled LM 833 when actually it is the LM 837N.

Some versions R164 is not used; @ms 2 & 3 on IC 151 are connected by C152). Some versions ZD152 is not used. Some versions R152 is 36KQ (instead of 33K on the schematic). The positive lead for R195 is not connected directly to the positive lead of the as the schematic depicts; instead it is connected to the junction of k%D151.
NOTE: These output transistors are k. equivalent:
