I'm waiting for this to be released, especially with the Lundall transformer upgrades. I have a TU-8200 I built years ago and it just doesn't have quite enough oomph for my liking. This looks much like a TU-8200 on steroids.


@vkung - Is there a list I can get on to order one as soon as they're available?
 
Error on label?

Victor,

I think there might be an error on the tube label, see attached. The 7591 (circled in red) is not pin compatible with the other tubes. Shouldn't this be 7581?

Regards, Steve

With all due respect

to you and especially Mr. Fujita, the 7591 has a different pin-out than almost all other power tubes. Plugging a 7591 into an amp that's stet up for 6V6, 6L6, EL34 etc. could do damage. See the attached basing diagrams.

With regards, Steve
