Very nice work! Did you build your speakers yourself? They're really something.

I am a bit glad speakers came up, for as much info on SET amps there is very little info on this site for modest high efficiency speakers, what are people without cad assisted machines doing for speakers. Are something like econo waveguides a good route to take for and amp this small powered. I have a pair of BR Fostex 127E but they just don't have any bass, I don't know where to look for info on modest budget horn setups.

For those interested in simulating their designs with SPICE, I developed a slightly refined DHT composite model using my own set of curves. A model is available for PSE as well.
Difference is on KP parameter which drives linearity of the model. With Dmitry's model you get a slightly worse THD response when swinging the 4P1L to its limits.

4P1L triode SPICE model | Bartola Valves

Hope this helps
Ale

Thanks Ale. As I mentioned before, if you ever find the time to trace the 26 would be great. Dmitry's model of the 26 I think is based on the datasheet, not a working sample.
