Hi Colin,

I thought it was odd because earlier on I had seen a post where you pointed someone to the Electra-Print site.

There's no pwr. supply for that 45 DRD posted. I'm interested in a 2A3 DRD myself, with SS rectifier, just like the Welbourne Labs.

Do you know how to alter the 300B one shown on the Electra-Print site? Is that possible, or just a good idea to start from scratch? It seems the B+ of the 300B is much higher and also as I recall the heater voltage supplied too is higher. So, perhaps a different transformer is in order?

I don't feel I know enough to design my own yet. I'm not very expert at electronics, just a rookie.

Mark
