Good evening.
As promised in my BAF presentation, here is my revised power supply filter / thump suppression switch.

Quick note: I replaced the pdf file with a corrected one a minute ago, so if you downloaded that earlier, do it again...
He who begs he shall receive. 🤓 Long awaited solution for my V-Fet amps, which powers sensitive horn speakers.
After sim, for quick turn off, the relay should have rated working voltage close to V+. By changing D2 or R10 to make the relay work at 75% of the rated voltage(70% is must on). In the worst case, the relay will release at 10% rated voltage. By doing so, It can short the turn off time.
My reply would belong in the Lounge section.
I speak English, but no muff joy here either.luckily, I'm lost there, English not being my native

Trying my math & intuition here. For a 36V supply and a 24V relay, R10 needs to drop at least 10.8V (36V - 24V - (0.6V*2) = 10.8V) and pass 8.3mA through the coil, so R10 = 130R?
Assuming the 10.8V and 8.3mA are the right numbers.....
10.8V/8.3mA is 1.301 K Ohms
10.8V/0.0083A is 1,301 Ohms
Off by factor of 10. Tighten-up your slide-rule, it is leaking zeros.
