Nice amp JC/Glenn, I'll probably get an OTL in '14 as well. But the next revision of course ;)


I think to really make these work for high impedance we would have to have custom OPTs wound with a high impedance secondary tap.  Electra-Print could do it, you could have an 8 ohm tap and a 120 ohm tap for example but it costs a lot more.  Then you just do an impedance selector like Woo and a dozen other makers use.

On the subject of C3g:  the ones marked POST were the batch runs made for Deutsch Telecom as a final buyout so they would have inventory available to run their obsolete equipment.  The ones without the POST marking were made for the German military.  According to Jac there is no difference between the two.  People prefer the POST ones because the very high run volumes supposedly help ensure good build consistency from tube to tube, but really I doubt it matters at all.  I have some of each, the non-POST ones are what is in my amp right now.

Your correct, Glenn says its the gain issue. I was thinking on a 300b amp that would be my last tube amp. At least for a long long time. Still plenty of time to figure this out since I'm still greatly enjoying my otl amp.

opps wrong quote.

300B is really nice, was listening to WA5LE before the game, it pairs HD800 very very well.

Can't wait how Glenn's offer with 5U4G/C3g/300B will sounds like.

Its been too long since I heard a 300b amp. last time was like 8 years ago. Some 300b amp running a Lowther speakers that was made in India I think. Forgot how it sounded back then. Can anyone describe it sound let say compared to the Glenn otl running 6as7?

Maybe Clayton? He probably the only one have both from Glenn.

My OTL is a headphone amp and my 300B is a speaker amp. So I can't really compare the sound using one type of headphone. However, the OTL is incredibly bold, vibrantly reproducing sound and the 300B seems to be much more transparent in the reproduction of sound. At least coming out of my Zu Audio Omen speakers. The 300B, compared to the OTL, sounds lighter to the heavier sounding OTL. Both have their niche and both are enjoyable.

^ YES! Welcome aboard, sir. We shall sail the seven seas on the USS Glenn Amp. You know, Sanraku is only a few blocks from my apartment. :)

It's like the OTL makes the air around the instruments feel heavier somehow, right?  It's easy to see why people love the HD800 with the OTL.
