Single vs Dual Power Transformers
The issue is power supply modulation, which can be very difficult to prevent! If the supply has noise (IOW, if the action of the amplifier has caused fluctuations in the power supply) the result can be intermodulations with the other channel runni... 
amp power & driver sensitivity in multiamp setup
Its probably that if the amp has only one output and no taps, that the 5 ohm load would result in less output than the 16 ohm load. If you use drivers that are 100 db 1 watt/1 meter (PHY?), then you have a chance with the 2A3 amp but I have my dou... 
Amplifier for Tannoy Turnberry GR
Atmasphere:Can you tell me where in Canada I can demo your amps? I live in BC but I also travel quite frequently to Calgary, AB. Well made amps.The closest dealer is in Toronto- address on our website. 
Tube Amp Maintenance Tip...
A good tube socket will have tin-plated pins and will last decades as in Wolf's Fender. These days we are seeing a lot of cheap sockets with silver plated pins- they will not last very long at all. Sounds counterintuitive, but in fact tin does not... 
Thought on OTL tube amps
If you want power, quite often "paralleling tubes is the only option" regardless of OTL or not.

No circuit boards :)https://www.youtube.com/watch?v=yodVDiEIpqI 
Mystery tube amp - name that amp
Looks like a very nicely done homebuilt to me. There is no conformal coating on the circuit boards so they are likely a very short run part. 
Tube Amp Maintenance Tip...
You really want to be careful about treating tube sockets with chemicals! If the chemical uses any sort of oil base the socket can be contaminated and problems (perhaps failure of the tube and requiring replacement of the socket) can ensue.For thi... 
Tube Amp for Avalon Ascendants
Actually the owners that speaker told us that our amps were the only game in town if you wanted bass out of the speaker. Different strokes... 
The new Tube Technology
I explored the Korg site when this announcement was made back at the beginning of the year. At that time it appeared to be a non-starter. It still looks that way...

What if it does?Even then it would not make sense. It contradicts itself. 
Thought on OTL tube amps
Futterman himself seemed to do a pretty good job at keeping the amps together according to one of our customers, although HP related an event in TAS that suggested that they could fail spectacularly.I heard rumors about the NYAL stuff being not as... 
Designer Hall of Fame
OV,who designed tube rectified OTL,using DHT tube as an OPT or any of the 7ac based tubes.Make it possible for kt66/88 or any 7ac based tube directly plugged into a 4 pin socket of a 6A3 single ended amp without amplifier mod. The comment does not... 
What do the different tube amp types mean?
Realdeal, there are no practical OTLs using 300bs, 211s or KT88s; just for the record. 
Dynamic speakers for OTL amps
?? Sorry- can't make sense of the last comment.
