@still4given,
Hi Terry,
I have 4 of the original P30ZF that alex mm designed and I believe you built. A quick question: "Do I need 1 pcb per channel or 1 pcb will cover 2 channel stereo. Need to know because I am going to sell some pcbs that are gathering dust.
Thanks for the help,
Myles

Hi Mister Mile, as usual one more nice amplifire. How many volts should we put in positve and negative rail, in order to work with 4R.

I don't understand. The P30 is a preamp. It's not meant to drive a speaker.
yes but it was just for testing. its now working with a40 and its fantastic. thanks for help.😀😀

Mr Mile, thanks for the reply, I made a new PCB. The old PCB took off tracks from the heat with excessive component changes. I will assemble it and make the change according to your orientation, soon I will post the result.Replace 4k7 with 3k3...

but in stereo PCB R680k dont connected to pin number4 of ne555.

about ne555 protection i have problem?!I have connected as in the drawing😕
now it's too late to make changes
It remains like DC and thermal protection
your drawing is correct or must add a overload detector too?
