Nothing changed only the mosfets.

Now all 4 regs with Zobel MKT+R because have less ripple.

Again, do a proper test on the mosfet you removed to be sure it was not damaged.

Was it replaced from the same bunch? Or bought at a different time?

Without bipolar BG 100uF 50V connected at the output sense + & sense- I have the same ripple, it's OK?

I have to change also the IRF610 to decrease ripple?

P.S. I'm like a boy playing with a new toy (scope)
This does not look like ripple. Looks random. As it is set, turn off the reg, to see what is residual pick up or isn't.

I can't see any difference at the scope with or without lytic turning off the reg.

Its probe's and scope's environmental pickup and its own residual then. If it was from the device under test only, it should have changed much when you powered it down.

It's a good news, I changed all Vref for MKT 10uF, now I just connected the real load (NP D1 I/V stage) waiting the regs warm up to adjust voltages (Salas your regs seems a F1 race), I try to listen tonight the I/V.

In CCS I had used thick film Caddock as better to MOX and metal film 1% on other positions, no special.
