Parks Audio Step Up Transformer for Moving Coils.

Shannon Parks does some awesome stuff. His Dynaco circuit board setups have always been the best overall designs when you want to keep the power supply close to original. They can also be messaged fairly easily when you want to go the distance......

Where is the thread or information about this SUT?

Dave is that a circuit board with some type of finish on the top?

Yes, its the first time I have seen this technique.

I am impressed with the simplicity of the design.

Shannon did that with his Budgie SE amp design. A PC board is the top of the amp chassis. Very clever idea.You'll notice this is a build by forum member Justin Weber...

Dave,

From one of Shannon's posts on the Budgie amp:

"... the top plate is completely done with all the cutouts and
silkscreening. Instead of aluminum, it is actually a PCB fabrication
around .100" thick, so it is very sturdy and looks great. It makes for a
very simple and fast build."

I see what you mean, I thought you were saying the top plate of the Budge amp was the printed circuit. It is in a sense, it serves as the ground path.

Here is the point to point SUT I have been working on, not quite as fancy as Shannons, but sure does sound good.

I have it mounted to a piece of Red Oak.

I need to change out the lowsy RCA jack, waiting for them to arrive.

The blue label I believe is the lower distortion version of the copper wound transformer. The ones I have are the same transformer Bob uses in his $850 unit.

Thanks, Dave

Here is the Parks version along side my point to point.

The one thing I don't like about the Parks is the micro switches.

Other than that, it great, and simple to build.
