Joule vzn 80 or 100 for merlins?

Do those Dehavilland monos use OTL tubes like Stargates or VZN80?

They use a large and strange SET tube, the name of which I can't think of. They are SETs, not P/P or OTLs.

The Dehavilland monos that output 30 watts employs the commonly used 845 triode output tube. The Joules use 6336C tubes. There's no such thing as a "OTL tube" .... it depends on the how the output tube is applied in the circuit.

FWIW, I use about 25 watts of SET power (Art Audio Jota monoblocks) on my Merlins, and I love how they perform. It should be noted SET sounds lot more powerful then its wattage rating suggests (relative to SS, PP, or OTL circuits). The Jota monoblocks are high current animals. For the same reason, I believe the VZN100 is a lot better then the VZN80 because of its better current delivery (monos versus stereo).

I have a Joule VZN 80 and don't want for more in terms of power. My room is 24'x13'.

By "not an OTL" I meant they were transformer coupled, not OTL. Hmmm...Does anyone know of an SET ciruit OTL? Also, I thought the DeHavillands had switched from 845s to a more obscure output tube. Am I wrong about this? My memory is that they went to this different tube in the latest version - too bad I'm lazy too look it up myself!
