I got used to multi-channel sound, made aleph 3 x 5 channels, did not apply filters at first, but I'm going to reorganize the power supply, the question is whether it is appropriate to make a CRC filter where the last RC go to each channel separately, distributing the load from the total C 2x100KuF => 5x (2x0.5ohm+2x33KuF=> amp.))? or it is still better to combine them .

and so it seems to work. The world's first wall-mounted amplifier.. maybe

it is always better if you can arrange better isolation between channels
so with separate RC cell for each channel, better isolation

thank you for your answer, I will try, the power is now + - 32 volts, there is a reserve

You are powering 5 unit of aleph 3 (mono) with that toroid ? Looks like 650VA at best on the picture....
EDIT: Just checked again (without DIY overkill thinking etc.) and I found 150VA per mono channel in the aleph3 documentation, so all my apologies.... I just seemed weird at first glance!

I bought it in a local radio parts store, it was not new , the description indicated 2x25v 2x15a, judging by the only inscription on it, I thought that this was fate

I would be grateful for the answer to the question: what is the mutual influence of two or more amplifier channels between each other, and whether I correctly understood that when the amplifier is operating, the load can be of a pulse nature, if so, what frequency / d-band. This I mean - is it not superfluous in the CRC chain to have a choke of small inductance and high Q-factor, say less than 0.5 mH? not for the purpose of reducing ripple from the network, but for better separation of influence.
in general, so-so idea, with small inductors, I stopped at RC in the amplifier block, but in the power supply I plan to arrange CLC, in the end I get CLC+(RCx5), after L cap at 220kmf, L=0.5 ohms 4mH, but here's the bad luck - what capacity should be in front of L and how important is it at all ? the catch is that there is not enough space. and in general, what is the profit from the throttle in the sound, because even so absolute silence even starts and turns off without a clap, and in general it sounds very good. I read a lot of the forum, and somewhere it was mentioned about the lack of a grunge effect in the sound. I didn't understand how. I'm glad that I made a bet on aleph pass 3, but I want to get the most out of the system. I would be grateful for clarification
I tried to listen to the work of the amplifier with the transformer disconnected, that is, at work from capacitors, banks of 220,000 mk.F, it works for about 1.5 seconds, on different saturated sound fragments, I did not feel the difference, then I will not build a garden with throttles. But what else to come up with? I picked up the transistors, removed the conder from the feedback, set the middle point, by the way, I changed the input resistance resistor and the type of capacitor 1nf, and obviously with 110k ohms and polystyrene shows the best taste of high frequencies and the depth of the scene, I changed it back and forth 10 times
