explination of circuit design

aardvarkash10 · 21st July 2010, 02:06 AM

RFI, or an offer?

I have tubes for this amp, I had a BP UltraPath made for me, but it got stolen. I have extra tubes and would like to build myself this time!
I would like to buy the transformers and other parts to do this. I remember looking under the hood and found the power supply to be the big design challenge. Any thoughts on this?

First requirement will be a schematic. Do you have one?

Was that the pre-amp by Welborne Labs? Battery powered?

They still are in business and list the manual so you might contact them. (Several sites claim they have been fraudulent in dealings in the past, along with showing complaints listed through the BBB).

I have never had any dealings with them.
