Hi Peranders,
I sent you an email but not sure if you got it. I'd like to buy 2 boards plus inductors. Can you email me at tuyettiATyahoo.com.

thank you,
Having trouble finding a source for JP1 and JP5. Looking for help finding them, even if outside USA. Would also like to source the specified heat sink, but that isn't a must. I have one I can mod to fit.
Thanks for any help.
Greg

JP1 is " standard " connector for flat cable, Greg.... I hope it will be not problem to find it.... JP5 are WAGO terminals, but you can use some " screw " one, not only WAGO...
Pavel, Thanks very much!
I'll search my catalogs for connectors of the proper spacing and see what I can come up with.
Regards, Greg

Completed 6ch Amp
Just wanted to share my implementation of 3 boards.
It's 700VA Toroid with 6 Secondaries at 27 Volts. (special) Softstart from Per-Anders.
Balanced XLR-Inputs
Hifi2000 chassis from Audiokit.it
Hot Stand-By with Signal sensor.
40 cm Fischer heat-sinks.
It's used in a 3-way active XOver setup.
I like the sound very much, it's crisp and clear, but still a solid bottom.

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

Looks good but a possible objection would be your 230 VAC wiring. Remember that all wires from my softstart is "hot", including the switch input. I would advise you to have "lampsladd" (lamp cable) for internal wiring. You should also tie them together better.
Personally I would have chosen shielded input wire.

OKI, I get it around the "lampsladd" 🙂 Will fix, it's.
"Shielded input wire" ... do you mean the connects from XLR --> Board input? ... Currently it's twisted with grounded wires so it should be OK shielded anyway.
It's very silent without signal, not the slightest hum or noise.

The case is a Hifi2000 "pesante" with extra thick 10 mm Alu frontplate. I bought it from Audiokit.it.
The sound is very clear and crisp. First impression is thin, but it's after a while you realize that it's quite powerful and has a great deal of punch in the bass as well. I'm using it in a tri-amp setup i.e. each amp stage drives one single driver directly.

Pavel,
I read about your intention to build an active crossover (Linkwitz-Riley?) and saw those pictures of a "sub"-board on the PA03 made by a friend of yours. Looks very interesting!
Could you tell more about this?
Best regards,
Menno

It is project of " CompromisLessCrossover " - CLC1 - with variable configuration ( 2 - 2,5 - 3 - 3,5 - 4 way ), analog - 24 dB/oct, with many setups ( switchable frequencies, phase correction, speaker correction, baffle step, subsonic filter etc... ). Project is still in developement, but I hope it will be ready this year... All is made by small modules, which are usable also in other equipment ... This is all in short... 😎
Holy crap!! 
Another work of art..
At one time I tried to design a simple LM3875 chipamp PCB up to Pavel's standards.. Needless to say I failed miserably and decided to continue to focus my efforts on my day job and let the experts do the circuit design.. 😀

Sort of off topic, sorry, but....
Combined with an input selector, passive pot or relay attenuator could these units be used as the heart of a pre-amp?

Yes Troy, it is possible... gain of this unit is 0 or +6 dB ( but you can set it to different gain ). Input impedance is cca 10 kOhm, output impedance is setupable 5 - 25 - 50 Ohm ( at both outputs )... You can use it as line driver or headphone amp...
