Thank's!PSE=Parallel Single Ended. In other words, both 845's connected in parallel to achieve higher power.
You answered my question though. Thanks!
On this time I go to build 300B PSE.
Hi! What do you mind PSE? Push-pull SE? No,just 845 driver push 845 output tube.. Pout=24W
Must be wonderful amp but very expensive.
I made my 845 with a sowter output and drive it with 5881 screen driven with 12HG7 pentode {peter Millet} . Only 750 volts for 15 watts, my speakers are 105db so don't need more power.

Solidworks is expensive, I made the model beacuse i needed files for CNC machines when making parts.
SW is not easy to start with and with the price I would recomend other solutions, I have license from my employer.
Tranny in the midle is a chocke on high voltage, it is on 10H and rated for 300mA. Voltage is 485Vdc.
A pair of VTA st70's for audio. For guitar I swap between my version of a Fender Champ and a Tweed Deluxe. The Deluxe is soooo sweet, but I fear the neighbors will complain! The Champ is my baby. I've messed with caps, speakers, cabinets, OPT's, grounding schemes, and tubes. Still haven't found what I'm looking for but in each step I learn and hear more.
Here is mine. Been my daily system for about five years. Can't add much to the conversation, because the circuits aren't my design. I did build them, and that's worth a photo.
On top is mostly tubelab se.
Middle is an aikido style preamp.
Bottom is the phono amp, also aikido topology and point to point.
Big thanks to Tubelab and Tubecad!

2A3 Tube Amp
An externally hosted image should be here but it was not working when we last tested it.
It takes two to bi-amp
GU-50, more power than KT-88, true pentode design. Preamp my own proprietary design, a mix of solid state and tube. Stunning clarity and powerful enough to drive 15-inch active-passive bass module. The other is 6L6GC running midrange and treble.
