Hello,
it took me again to make myself a new amplifier. This time I took a PCC88 (TESLA) for the input triode and phase shifter. As the final tube, I used 6E5P in triode connection. The result is very encouraging.
Another interesting thing, I used a cheap Chinese switcher (approx. 35€) for the power supply.
Not bad at all...

Nice. It's been on my list of things to do to make a 6e5P push pull amp. It seems like such an obvious amp to make, but I have only seen a handful out there.
How much power are you getting out of the PP 6E5P?
I have a ton of them to play with, if I ever get some time...

Very interesting! Nicely built. What are the specs of the required output transformer? What did you actually use?
Output transformer:
home made from one my friend a lot years ago. EI78, With 3.5K primary and 4 and 8Ohm output. RDC about 90 Ohm. 4 sections primare and 3 secondary.

Great! I have a good but unused pair of PP transformers with 3.4k primaries that I could use when I try your amplifier.
Apart from power, is there any difference in sound with the 6 x 6e5p PSE you have. On another forum you say you have 2 better sounding amplifiers, which one?
6 x 6e5p PSE has around 9W-10W. So the sam power. PP has much better bass, mids and it is no so "sterile" as PSE. This is probably because PSE is one stage and PP is two stage amp.
My bests soundig amp is SE GU50 in penthode with driver E180F in pethode with shade feedback. G2 of GU50 (300V) and G2 of E180F (150V) are regulated. OT is 5.2K. My second best amp is 6C4C in PP - https://www.diyaudio.com/community/threads/6c4c-in-pp-loftin-white.331167/
