CR-1604 THERMAL SHUTDOWN

Model:

1604, mainly ser#’s in the 35,000 to 55,000 range.

Symptom:

Gets hot, shuts off, especially with XLR-10.

Cause:

Voltage regulators not properly seated to chassis (heatsink).

Fix:

Reseat Regulators.

Notes:

Some may have TO-220 case regulators with totally plastic packages.
We recommend using the 7815 / 7915 with a metal tab for better thermal
conduction.  Remember to use mica insulators and heatsink compound.
