The tubes are out, next is a piece of plywood and some testing.

2 stage SE or adding a dualtriode for a LEAK style PP.

I was very spendy and went for EL36 with 6.3 heaters .

Back from an urgent organ amp repair.

The patient survived surgery and will now live another 40 year or so.

The cheapskate me have a couple of non tube irons on the bench right now.

Spec says 15w 30-20k within 3dB and costed 3.40 and they are a 8K PP in discuise.

Its cheapest amp challenge .
