Where Have All the 2A3 Amps Gone

Isochronism, no problem. I thought you were serious because it seems 45s are more available. But I did find a 2A3 in Virginia. I'll respond back with my findings.

We are working on a push-pull 2A3. Expected power is 16 watts.

It is a pity. I was hoping, that we will get more high efficient speakers in our modern time (with our technology it shouldn't be problem), but there is no change. Always the same 86dB-92dB Speaker Stuff.
Some years ago I listened to such an amp with a good 100dB System and it was very good. Some say, the truth is in the first watt...
But unfortunately it is a real task today to walk that road...

Atmasphere, That's good news!!! 16 watts is just right. Hopefully you'll offer 16 ohm output trannies too. Can you say approximately when it will be ready?

Atmasphere, forgive my ignorance (re trannies). I didn't know it you. Your current amplifiers are OTLs. Question for you. My speakers are Zu Presence which contain an onboard subwoofer amp. Are there any concerns connecting your OTLs to such a speaker?
