Interesting.

Heard a pair of mono ones once - boy did they run hot with a very direct sound. However the idea of OTL freaked me out so I didn't go there.

yes no need for extra heating in a well insulated room , I'm a big OTL fan
and I find well designed and constructed amps are as stable as anything in fact more so than some valve amps as no output trannys to damage
mind you the 26v dc my Graaf was putting out of its right output the other day due to a faulty driver valve was a bit scarey:eek:

Looking at that, you'd hope they were cheap as chips.

I think he's built a few before:D
