Default Soft start + switch on PCB

I'm just completing a high quality double sided, silk screen PCB which contains a soft start circuit plus a power on circuit. The power on circuit enables any switch to be used (doesn't have to be mains) to power up your amp - broadens selection of switches available for front panel. The soft start simply limits the inrush current when power is applied. If anyone is interested I could make these available as just PCB or with all components.

I've got no intention to ruin your enthusiasm, but while you're at it you might check out the soft start circuits from www.lcaudio.com and, particularly, www.hypex.nl. I've just bought two of the soft starts from Hypex, one for each of my power amps, it allows both 115 and 230 V mains, LEDís for standby and power up, pushbutton or switch and a PTC ęthermal fuseĽ/overheat protection. The only complaint I have about the Hypex thing, is that it should have a regulated AUX power supply output for other switching purposes for example (it has a small 12V 2VA transformer).

best regards

KJ

Thanks for the links. I prefer to build all my own stuff - so, yes I could buy ones ready made, but it's not as much fun!
My board is a little larger than the hypex, but contains essentially the same functionality - soft-start (not with triac), remote power on (ie push button or other switch), individual LEDs showing standby and power on + the ability to adjust the intensity of the LEDs - I like to be able to do this to suit the room.
The one thing I don't like about the hypex is the exposed terminals for the mains voltage. Even though they say to use insulated faston connectors, I prefer enclosed terminal blocks.
An image of the PCB layout is attached. The boards are in production now.When I have built and tested them I will be able to offer bare PCBs for anyone wishing to build their own. Likely cost around US$20 per PCB (double sided, plated through, solder mask and silkscreen)

Boards complete and tested. I've attached a pic of the finished board. I have only designed it for 220-240V operation. If there is any interest I can provide bare boards, boards & parts or complete units. Board size is 168x97mm
