Been restoring a Pioneer SA-1000. Got to the main amp boards and after completing caps and transistors fired it up for a test under DBT and discovered R1 ( 330 ohm) on the power supply board started smoking. Before I start checking components on that board, what would my best/ logical approach be? The pioneer service manuals are excellent as far as details go , thinking maybe I'm missing something obvious??
EDIT: my bulb dimmed out on power up. Also the power supply board has been recapped already and re-transistored.... After completing that board I checked the unit with the dbt but just briefly to confirm no shorts...
