Raulinruegas, I'm not insulting you, but your description of our product just happened to be something that has not been documented in nearly thirty years of business. I had to call you on it plain and simple.
Like anyone else in the business, sure we've had failures. But not 'blowing up' on account of a tube failure! which is the context of your statement. As an OTL manufacturer, we had to face the prior legacy of Futterman et.al. who had convinced the world at that time that OTLs were unreliable. We had created a way to make them pretty well bulletproof, so that a tube failure, speaker short, open input or total overload could not damage the amp.
I'm well-known for doing stunts with the amps at shows- pulling power tubes while the amps are playing, shorting out the output while the volume control is turned up to the limit and other things- things you would expect to damage an amp if you did them.
One time I had a tube arc when I had the speaker terminals shorted during just such a demonstration. No big deal- the amp was playing as if nothing happened when I removed the quarters I was using to short out the speaker terminals.
So you chose to describe the the one thing our amps *don't* do. So of course I had to call you on the carpet. In order for these forums to work you have to stick avoiding misleading comments.
