As far as I can see you could do two things: First, place the bias circuit on a board so it seats low on the chassis and move it closer to the PT. BTW you have too big a cap there, it calls for a 100 mF @ 63 volts which is way smaller than the one you have there now. Secondly move V1, V2 and V3 to ...

So I decided to built a 50watt Hiwatt with a few twists.

On the way I changed my mind and I will follow the original version of that design (DR504) ...

I appreciate the help guys

Hi

I was wondering if anyone came across any schematic design software that has also analysis capabilities ( i.e. LT Spice ) that can run on Mac OS.

At the moment I have all the parts at hand beside the transformers and trying to design a layout from scratch in ord...
