Glenn,
Looks as if these amps will go as soon as you turn them out.

So far I had no interest in this amp only jelt2359 wanted it.
And I think this is the best sounding amp I made so far.

Your amps always have my interest.

Glenn,
Amp should sound even better going from 4 to 2 tube design?

A Loewe Radio AZ12 arrived today. I assume it is 1930's vintage based on the globe-shaped bottle and mesh plates.
 
Again, not suitable in a Glenn OTL running 6AS7G but more than adequate with a quad of 6BL7. And this would be fine in a Glenn EL3N too.
 

 
Lights up pretty nice too!

The "one-stage" setting I'm referring to in my posts is the 2 tube version. Anyway a buddy of mine- speaker fella- heard my GEL3N and was transfixed. He immediately asked if he could get one as a preamp. Waiting for Glenn to get back to me now

Nice looking tube!!!!
With it's 200ma plate current you might get away with using 6AS7s

Yea but

To bad these tubes didn't have a normal octal base.

You guys have any recommendations on which amp with what upgrades pairs well with Senns? Mostly use my 580/650/800 these days, though I wouldn't object to being able to power some efficient orthos and low Z headphones in addition to the Senns.

My Dac will either be the Bimby or gumby.

If the low-Z headphones are efficient, such as the TH-X00, the Glenn OTL will work well. If you wish to use inefficient low-Z headphones, such as HE-6, then a transformer-coupled amp, such as the Glenn EL3N or 300B would be preferable.
 
As Glenn voices his OTL with Senns, that is a match made in heaven.

OTL it is then, my Senns are my main headphones and will likely remain that way for some number of years.

Any recommendations for the upgrades? I was thinking of getting the Lundahl transformer upgrade, trying to look up impressions for it now.
