RE: high frequency AC

I purchased two of the 105 watt versions.

I have added two turns to the output transformer and hopefully will start testing tomorrow. There are 12 turns giving 12 volts. Hopefully the additional 2 turns will make 14 and with the cap (560uf 200v) multiplying by 1.4 I should get 19.6 v which is close enough.

It was easy to add two turns, but three would be tight.

I don't have access to a true RMS meter that can handle the AC frequency but I have an idea for another method to measure the voltage.

I am building the amp right now and it is designed to be light weight (12 pounds).
