I bring up the voltage gradually on the variac and watch for excessive or anomalous current draw on the meters and keep an eye out for red plating on the tubes. The slow start up is mainly for the lytic caps in the power supply. If they don’t get powered up in a while they dry out. They can sometimes be reformed if you bring them up slow.

Output of source into pin 1&2 of “preamp” octal socket for the input with volume control. For 8 ohm load, plug pin 1&4 into speaker, and jumper pin 1&5 and 3&4 of “output” octal.

For 16 ohm connect pin 1&6 and jumper pin 2&5. Pin 1 is on the right side of the keyway and the pins go in order with pin 8 on the left side of the keyway
