I have just purchased the latest Sound Lab M1

Yo Ralph.
Dave did say something like that but what was meant was that the least this amp is, is an OTL, the least it is! So that people can get a little grasp, because it's not output transformer coupled, so then what is it???

Having a transformer that does not operate at audio frequency or anywhere near it, is not a audio output transformer, as Dave has pointed out above it would compare to your power transformer, then if that's the case neither of our amps are OTL's !

After all, this technology is to over come all of the OTL's troubles, as noted in your posting, with the Futterman as well as with many other OTL's but with keeping all of the positive sonic attributes of an OTL.

You have to remember Futterman came out with the OTL in 1954 and his primary reason was for cost savings, he eliminated the audio output transformer because they were costly and he had access to tubes so he could load up the thing with a zillion hot tubes, now Dave's invention does away with both the audio output transformer and the Zillion smoking hot power hungry tubes, just because this is so radical, does not make it an output transformer coupled amp, or anything else other than an invention of tube amp technology with responsibility suitable for modern times.

So that people can get a little grasp, because it's not output transformer coupled, so then what is it???

Why don't you call it what it is? An amplifier coupled by an RF transformer, bypassing traditional output transformer problems? Instead of making up stories about how a transformer isn't a transformer- sounds a little like the Emperor's New Clothes after a while.

That children's story is not just for amusement- it was devise to teach to children how a story can be made up merely for purposes of looking good, or failing that, not looking bad. And what happens when you see through the story.

Oh Ralph.

We're not making up stories, we're telling it like it is, our patent is available for all to see on our website.

There are those that understand it and those that don't, simple.

You'll have to sort out which side of that understanding you are on then. So- by you: a transformer is not a transformer and semiconductors are not semiconductors.

A transformer is a transformer, a audio output transformer is something else, As I said before Ralph, there are over 2 dozen transformers in these amps and not one even comes close to being a audio output transformer, if you can't understand that, what else can I say man.
