Dear workhorse
I'm talking about post no. 140 & 141
can you please share SCHEMATIC WITH PART VALUES for front preamp and display mgmt
& power supply board (ac-ps-fanreg-protect_board)

Those pcbs are separate from the project and currently not associated with it, therefore no help in that case.
Dear workhorse
Please if you don't mind, can you give details of where this information can be found, about post no. 140 & 141 (related) or can email me.please

sorry, i already built it & very nice output but did not fit in the cabinet because I have not found yet front management PCB.
Thanks for sharing one of the best Amp PCB.

Workhorse, If I double the transistor output and raise the voltage to 75vdc 150vdc 3KV rms will I get?
Yes, but then you cannot use 2sc5200/2sa1943 pairs, because its breakdown voltage is 230V only and with 75V step the total voltage reflected would be 225V gives very little margin better go for 250V rated transistors if you want to increase the rail.
Thanks workhorse!
work with 18 "speaker 8 ohms each in parallel 800wrms. 2homs Total 3600w rms. I really enjoyed your amplifier. What tension and how many transistors in the output to work? The transistor output can be separated from the card drive? Sorry my inglish. Greetings!

KAYLAN,
Where are the pics?
Try MJL21196/21195 ONSEMI pairs with +/- 80 and 160VDC steps.
9 pairs are sufficient including driver stage and MJE15032/33 for pre drivers

I am looking very powerful amplifier. After several attempts. I decided to try to build 1K5 Workhorse.
First difficulty is the double-sided PCB. I resolved this by building two separate PCBs and then unilateral.

An externally hosted image should be here but it was not working when we last tested it.
