Craig.. Try a new IC. I just had a Symphonic..VCC voltages on IC were low and supplies showed low every where, replacing IC and set worked.

Nearby fusible resistor is ok. I wasn't even looking for this voltage I was only looking for 25V but now i notice related 12V voltages missing everywhere. IC202 (TO-220 with snap on heat sink has 17.5 volts in nothing out. Pin 2 is gnd. No diode or resistance measurements between the input and output. L7-M08 or ECG 964 Don't have a print but I think I'll try a new IC Craig n a message dated 9/29/03 9:49:23 AM Eastern Daylight Time, peggs@xxxxxxxxxxxxx writes: << May be a B+ missing to the Jungle IC's Vertical Osc./Drive circuuitry. I seem to remember these having solder problems on the TO220 regulators.
