Peek into the Workshop : Preamp Power Supplies Assembly


I have been a bit lazy with posts recently. I'll try to show more in the next weeks. Here a peek into the workshop.

A phono stage and a line stage are in the process of being finished. Started with the power supplies.

The top plates with tube sockets and resistors mounted.

Next the power transformers and oil capacitors.

The heater and filament transformers are mounted on the bottom side:

Wiring up the transformers:

Adding the chokes:

Adding the caps for the heater and filament supplies.

Proper operation gets tested before the preamps go into the enclosure and front and back plates are mounted.

Finished PSUs:

Back sides:

Next the signal sections will be built.

Best regards
