Input snubber
Sorry, newbie question coming:
I am thinking about using the Toroidy Audio Grade 400VA 2 x 18V. Does someone know the values for the input snubber (or can me help to interpret what I have found)?
500VA is said to be Cx: 10nF, Cs: 150nF, Rs: 7Ω / 7Ω. (On this list.) I can't use that for the 400VA, correct?
Someone measured it in this discussion, but I'm struggling to understand which value to use practically.

1)
2) The input snubber is something worth doing. (Ignore the output snubber. ) Because you are using the AS-4218, I know that the values of 0.01uF+12ohm and 0.15uF work well.

On the First Watt PS drawing, could the capacitor in parallel to the 240VAC line, be something like that ?

For a class AB amp, do you think dual mono is better than 2x capacitance shared? Or does it depend on the magnitude of the capacitance being doubled?
For example, on a 150W @ 8 Ohms amplifier, would you rather have 20mF per rail per channel or 40mF per rail shared by both channels?

6L6Just saw this.
No. Don't do that. One thermistor in series with the AC primary only.
The other CL-60 goes on the output of GND at the power supply.
The wires that run to and from the PS board appear to be a fairly large gauge, what gauge is best for that application?
1. Utility Knife
2. Steel Ruler
3. Patience

That is exactly what I did !

Exactly! I ordered power supply boards twice over the past year-and-a-half and both times they were snapped apart, courtesy of the US Postal Service. I hope the diyAudio store has found a better way of packaging other than in lightly padded envelopes which are easily folded to stuff into a mailbox.

Anyone can tell me if I missed anything here (beside the led ) ?
