Does anyone try these in a PSU for a solid-state amp?
I am contemplating a CLC design with a single large inductor bank (88,000uf) followed by 4 channels R/L and +/- 24 vdc respectively each with a separate inductor and 33,000 uF cap feeding the output. Each channel should draw about 500mA. I've only built supplies for tube amps and am not too sure what the issues are with a design that doesn't include a 'huge' 4 H inductor and much less capacitance. I ran the simulation in PSU II and it looks great. This seems a great option at a cheap price. I was trying to find something similar at 2uH but this seems like it would work. I know with inductors I need to be concerned about saturation but this looks fine at this current at least if I understand the specs.

While the 4H inductor in a tube-amp psu serves to smooth the ripple, best this 150µH choke can do, is to filter out some HF noise.
I wouldn’t really call this a CLC design.
For a CLC supply I would look for something like this: https://www.hammfg.com/electronics/transformers/choke/153-159

Thanks I have used similar designs to the one you propose on tube amps with 4H+inductors and they work great.
This is for a solid-state design that proposes CRC with a 0.1 ohm resistor which seems different from a tube design. Also the voltage is 24VDC, not 400 VDC. The PSU examples I have seen for this amplifier are either a CRC design or have low inductance (2mH) air core inductor either is paired with high capacitance. My design I proposes using this lower-cost toroid inductor of a higher value. According to PSUII designer, this is an improvement but I don't know if I understand inductors well enough and if there is some reason this style inductor won't work for this application.
The original CRC design with the 0.1-ohm resistor is ~100 mA of ripple. The ripple of the CLC design with the proposed inductor is under 200 uA

At first you may learn to discern voltage from current and amps from volts. As a simple rule of thumb, the inductor for the ss-amps is as bulky as the inductor of a tube amp. The toroids you choose are way too tiny to form a significant CLC filter. Such inductors are massive, the bigger, the better.
