Build a simple MONO first. Then use the lessons learned in doing it correctly to advance to a two channel build.
for MONO I will need only one separate CRC filter? where I have to get ground from PSU?

An externally hosted image should be here but it was not working when we last tested it.
Ground is where we say it is.
If the center of the PSU has GND in the middle, the amplifier can push the speaker from 0v to +25, and the amplifier can pull the speaker from 0 to -25v, giving a total swing of 50v. The neutral point is GND.

no, 6L6 ......... that's simply wrong ..... meaning - irrelevant
just ask him (6767) what he prefer ........ besides having (hopefully!) left and right leg .... to also have one middle leg ............. or to have another right (or left) one ?
Tautology is a thing - I'm not smart enough to change by myself , so I must obey what it means . Same thing with power supply .
maybe I'm picky these days (almost feeling jet lag all the time , even if I'm not meteopath nor I flew lately ) but there is avalanche of Neotechnology kids these days

anyway I realise that I am noobest noob so i am very thankful for education. really.
and should learn about push pull amps I guess

I have a F5T with the the Toecutter V.3 boards. I am planning a dual mono power supply within a Deluxe 5U aluminum chassis from the diyAudio store. I am using two Antek AN-5225 transformers and the diyAudio PSU boards to build left and right complementary +/- 32VDC supplies. Question - to avoid interference with the heatsinks and the circuit boards, what is the best arrangement for the toroids and the PSU boards ? Can I stack the toroids without causing magnetic field problems ? Should the PSU boards be mounted on the front plate ? I am using four IXYS VBE 55-06N07 FRED bridges.
When replacing the jfets on jims audio boards with not fakes, remember to turn the 174 180 degres.
Where did you buy your Jfets? Jims 174 is fake it is 2sj103 And he admitted it to me.
the j174 has the same pin out as the 2sj103.
Both have the Gate in the middle. j174 states that D & S are interchangeable.
But I bought new fets from diyaudio turned the 174 and now it sounds perfect. Also I was told to do that from another member here.

Really ? Are they PNP or NPN ? I always thought that all semiconductors were "left or right handed" like diodes.
Well, fellas, I just opened up the box holding the 5U chassis parts. Holy Cats - this thing is big enough to put out as a doghouse for one of my Scotties ! I don't think I'll have any problems fitting the power supplies into this case and clearing the case.....plenty of real estate.
i just finishing building a Pass / Sony VFET amp in a 4U chassis and it was tighter than I though it would be, even with a 400VA transformer. For some reason I thought the 5U chassis was just taller, not 4" deeper.
Anyway, what is the consensus on where to mount the capacitor boards ? Mounted flat to the front face plate or stacked vertically ?
I think for air circulation around the filtering resistors, mounting to the front face plate makes more sense....might work better with the IXYS bridges also, since these want to mount to the perforated base plate.

I do not know if I shall understand this as, it does not matter if D and S change position, as long as gate is in the middle?
