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.

RT1 ~ RT3
�
A high-frequency compensation capacitor must be connected between RT1 and RT2. A low-frequency compensation capacitor must be connected between RT2 and RT3.

Tone control output. Super bass input. Must be driven at a low impedance. Connected to GND. Not connected. For the connection of RCH super bass compensation capacitors. Fader input. Must be driven at a low impedance. Fader output. The front and rear sides can be attenuated independently. GND. Serial data and clock input for control. Chip enable. Data is written in the internal latch when the chip enable signal goes "L" from "H", and each analog switch is activated. Data transfer is enabled at "H". Generates a 1/2VDD power source. A capacitor must be connected between VREF and GND as a troubleshooting against power ripples. Fader output. The front and rear sides can be attenuated independently. Fader input. Must be driven at a low impedance. For the connection of LCH super bass compensation capacitors. Not connected. Connected to GND. Super bass input. Must be driven at a low impedance. Tone control output. For the connection of capacitors that compensate for bass and treble in the tone control circuit.
