Cobra 2
That is heavy, 200lbs, The first amp I built was only 95lbs, I thought that was heavy! There is a 100watt monoblock which only uses 2 EL34's in the book by E. Rodenhuis called Valves for Audio Frequency Amplifiers printed by Audio Amateur Press. It also gives you the wiring diagrams for the power transformers chokes and output transformers also all the measurements. I have the book.Should make a good powerful amp. Regards.

Weight...make good amps / iron really expensive to ship...to where I'm living. Unless someone can tow them trafos behind a freightship...

The good thing; they are (almost) theft-proof.

BTW, I have decided to make a long story shorter, and bought a restored & updated Dynaco ST70 here:

If I get the taste of it...I will jump into over my head again.

What's the voltage in Norway? If it's 240 you will have to lower it to 120. Are you having the ultralinear switch? I hope you get many hours of pleasure. Regards.

Good iron might still be cheaply availble from those Eastern Europe boys. After all its almost current technology over there. Postage is usually reasonable from that area.
A road trip might even be in order.

The Dynaco looks like a good cheap purchase.

The Dyna is ordered with a new "PA-521" transformer (has double primary).
