Interesting. I was on the wrong track then. So, it’s a parallel single ended amp with KT88 tubes in triode mode? Or yet another type of circuit? I’m curious.
Hi Jan, here is the reply from the person who restored the amp.;
Hallo Leon,
Ik heb helaas geen info over deze versterker, ook geen schema.
De eindtrap staat in classe A, dwz het pos en neg deel van het signaal gaat door èèn buis.
De tweede buis staat parallel om meer vermogen te verkrijgen.
In tegenstelling tot classe B/C, daar gaat het pos deel door èèn buis en het neg deel door een tweede buis. Ook heb je hier een inverter buis nodig om een pos en een neg signaal te generen.

Hello Leon,
Unfortunately, I don't have any information about this amplifier, nor do I have a schematic.
The output stage operates in class A, meaning the positive and negative parts of the signal pass through a single tube. The second tube is in parallel to achieve more power.
In contrast to class B/C, where the positive part goes through one tube and the negative part goes through a second tube. Additionally, you need an inverter tube here to generate a positive and a negative signal.
Hope this is the right information to understand what this amp really is.
Thanks. Definitely single ended triode. Pity there is no further information about the amp. The Blueglow KT88 SE that I built and that has been mentioned a few times on the Skunkie Youtube channel is switchable between ultralinear and triode. Triode sounds better.
This are the pictures from the seller. I have the amplifier at home now. The sound is just " live ". After a few hours listening i went back to my Sansui AU-719. I thought that amp has broken down. It was fine but that is how good this tube amp is.
hi
AE-Europe in Schagen, Holland? Is this one of Triode Dick’s designs?
