Yup start at the STK's
Almost all brands have the same set-up. Look for cold joints
then the low watt resistors. The voltage to run them comes off the FBT
and often is both plus & minus supply. They are typically fused
by apx 1 ohm resistors. Use flameproofs NOT old carbons. An open
resistor will point to a shorted STK or rectifier diode.
