Thanks @Bigun - my apologies for my ignorance but : which design you are speaking about and who's Tim Mello ? 🤔

Here’s a link.

All this OTL stuff is quite new to me, eager to learn.

Ah, OK - I see - thanks !
Why not ? I would be worry though by the proximity of the 6C33C vs. the other parts, about temperature, and rather choose a larger chassis and/or a much more serious cooling (i.e. chimney effect around these power tubes, like I do on my U-OTL). In fact, those big 6C33C not only heat the air, but also generates much infra-red !
To give an idea, here's the temperature I took on the top of one of the 6080 on my U-OTL : 190°C at 5mn after starting :

Hi Tubelectron,
The thread popped up again, nice! I read a lot through it when you were building the amp, also a lot of proposed modifications and so on, so my question: can you post the latest schematics? Maybe even better if you could post it in the first post of the thread (ask a moderator)?
many thanks, Erik

Got any real test data to shew us? Like THD & watts at clipping into a resistive load.
'It sounds OK' isn't much information for people a World away. with different speakers & on & on.👎
