Very good quality, prompt response. This website has reasonable prices and wide range of manuals that are hard to find.

The document was usefull, and it was exactly what I was looking for.

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.

Separation Corona
Optimum Adjusting Values: AC 57.0 ± 2.0 µA (D1) DC -8.0 ± 1.0 µA (leading edge: D1) DC -2.5 ± 1.0 µA (normal: D1 & D2) 1. Reinstall the TC/SC corona unit, and position the drum shoe at the center of the shaft so that the axis of the current sensing plate [A] is aligned with the separation corona wires [B] as shown.
AC current: D1 2. Select the ac 200 µA range on the digital multimeter. 3. Turn on the DIP switch on the switching PCB corresponding to �D1� on the TC/SC power pack PCB to turn on the separation corona. (The silk screen printed on the TC/SC power pack PCB is correct.) Adjust the corona current by turning VR �DAC� [C] on the TC/SC power pack. (Wait 30 seconds for the current to stabilize.)
4.
Leading edge dc: D1 5. Turn off the main switch, and select the dc 200 µA range on the digital multimeter. 6. Turn on the main switch, and adjust the corona current by turning VR �DC1� [D] on the TC/SC power pack. (Wait 30 seconds for the current to stabilize.) Normal dc 7. Turn on the DIP switches on the switching PCB corresponding to �D1 & D2� on the TC/SC power pack PCB to turn on the separation corona. (The silk screen printed on the TC/SC power pack PCB is correct.) 8. Adjust the corona current by turning VR �DC2� [E] on the TC/SC power pack. (Wait 30 seconds for the current to stabilize.) 9. Remove the drum shoe, and reassemble. 10. Check copy quality.
