4 diodes, not a GB bridge (soft recovery, schottky, smd, etc) - shorten tracks by Input one end of pcb & o/p the other end - snubber is applied directly across sec winding = 0.01uF in // to a 0.15uF + 1/2 watt resistor to suit (Haggerman type) - add option to use 2 resistors in '+ rail' and 2 resistors in '- rail' for the C-R-C filter - add option for extra resistors for R-C-R-C filters - Single layer, NO ground plane - maybe R + led indicator - optional power load resistor on o/p - etc

3.
snubber is applied directly across sec winding = 0.01uF in // to a 0.15uF + 1/2 watt resistor to suit (Haggerman type)

4. add option to use 2 resistors in '+ rail' and 2 resistors in '- rail' for the C-R-C filter

5.
add option for extra resistors for R-C-R-C filters

6.
Single layer, NO ground plane

7.
maybe R + led indicator

8.
optional power load resistor on o/p -c

1. board is so small, 5x5 cm, no room for disrete diodes, complicates layout, but OK maybe

2. no room for conectors on sides

3. OK

4. dont understand, this board is for one rail not for both (you need two), it has CRC (pi) filter

5. maybe

6. no ground plane OK, but needs 2 layer

7. I'll try to find room

8. bleeder, OK

So same traces on both sides? For less resistance? This makes it very hard to de-solder and remove components without braking one side traces?

No, last version is without that.

OK! Well, I'm devoted to SMPS (+ C mult) so I will pass this one. Still, a welcome contribution I'm sure.

Best to keep line carried noise, charging current pulses, etc concentrated in area of raw supply and as the cct on post #790 requires +/- rail volts with the single 0 volt connection, use single pcb for both rails, despite the larger size and feed maybe 2 CMx (for 2 channel signals) - look outside the square a bit

Single layer only maybe - simplify tracking and avoid capacitor 2 layer thru hole soldering - maybe larger smd power resistors underneath - is central 0 volt point connection at input, output of CMx board(s) or another point in the circuit (following regulator, active circuit, etc)?

Some suggestions only ...

* added faston terminals
* added input snubber, cap two footprint, 1206 smd + 0.2" through hole
* added output resistor (bleeder)
