37-690 rectifier flash / arc
#6

My personal preference of power-up:

1. Without any tubes, check the transformer for the proper output.
2. After full recap, repeat.
3. With all tubes in and speaker connected power from Variac via isolation xfmr and see the DC, a reasonable level.
4. With no Variac, power up and see the DC rise fully over 10 seconds or so, and then droop a little.
5. Wait with your finger on Off switch. If in a minute nothing bad happens, proceed with full check.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
