SERVICE MANUAL P O W E R AMPLIFIER C-800/1200 http://www.inter-m.com MADE IN KOREA NO: 9007979650 ELECTRICAL ADJUSTMENT PROCEDURE IDLE CURRENT A. Setting Set the master volume minimum. B. Connection TP1 R146 R246 R149 R249 TP2 VOLT METER SVR101 AMP B D SVR201 C. Adjustment ­ Adjust SVR101, SVR201 so that the current through the R146, R149, R246, R249 become 10 milliampere. ­ When that voltage across the Positive "TP" to Negative "TP" becomes 10 millivolt, the current becomes 21 milliampere.
