Hello friends?
Am I crazy?
What would be the issue of driving speakers with an OTL parallel SET of 6s33s?
Thinking about it needs great cooling, a super refined PSU, and the excessive current output...
Found on the web either parallel OR OTL...
What's your take, you tubes experts ?
Let's see if something manageable comes out!

Well, I guess it can be done.
I once built an SE OTL with 4* PL504 (27GB5?) per channel, running at something like 120V 100-110mA each for a whopping 0,75W/ch.
The cathode load was an EI78 transformer core with 500 turns of 0,5mm wire and a 0,4mm airgap, IIRC.
Sounded quite good with the right speakers but the power consumption and heat was a bit over the top, something like 250W at idle.
If I whhere to do something similar with 6S33S I would put a fan right under each socket, those things have a reputation of running hot enough to destroy soler joints and sockets over time.
