Loudspeaker Protector

power thermistors

Yep, may be an option I'll investigate if I ever make a Mk2.

For now, I'm happy with the 100mS curves.

Thanks for comment and suggestions.

Any interest in PCBs and PICs ?

Guys, have had a few enquires regarding supply of PCBs and PICs for the Protector/Softstart recently.
Is there any interest out there ?
Is cheaper per PCB the more PCBs that are made in the batch.

I also made a multi-channel expander card as well for this project so please advise if any interest in multi channel amps (the std PCB is for stereo).

As usual, I will pass these on at cost.

Please advise.
Thanks and Regards.

Part Substitution

Hi Muzza
Got my pcb's built up but not yet tested. I am unable to get hold of R180's for Soft Start section. I am planning to substitute with
3 x R220's is this likely to be O.K. or would 4 x R220's be better?
You may remember that I will need to double up on the above quantities as I am running 2 x 500VA toroids/soft start.
Your advise appreciated.
