Post Subject: Anthony DSET Power Supply SchematicPosted by anthony on: 1/16/2017
To keep with Romy's spirit of sharing his work, I have attached a file of VER 1.0 of the DSET Power Supply.  There are quite a few differences to Romy's published schematics but it is basically the same beast.  You will notice a lot of power transformers in each supply, 10 in all including 4 separate filament transformers, the services toroid and five EI's for Bias, DHT, drivers and power stages.  The relays got a bit complicated after I ordered the wrong coil voltage for the time delay relays and then had to go with it.

The biggest difference to Romy's schematic is that I have added a dedicated DHT power supply.  This is a double choke LCLCR with 8,000uF final filtering cap. 

Power transformer ratings have been re-worked to suit the new supply arrangement and chokes are all sized and properly gapped for those currents.
