Default Prototype

The Prototype sounds very good. More information to come after testing. The design is by some very smart guys on the forum. Not me. I'm just helping build it. Thanks, Mike.

Looks nice. Insides look neat. I can never get them to look like that.

But what's it all about? FET, Bipolar?

Do the front and back ends have seperate transformers?

Very nice construction. I'm sure details of the design will follow sometime. Looks like it needs beefy power supplies. Class A? Why all the unused spots on the PCB, reworked design or future configurations? Again, clean build!

Sandy.

It can be class A or class AB. I built this one to prove out the board and didn't have enough outputs MOSFETs to put all ten in. The next one will be bigger.

I am going to change the output to +/- 18 volts and run it Class A.
