Yes. Vcc=24V - 120k, Vcc=12V - 47k. Accordingly, a relay with a coil for 24V or 12V.

Thanks again, Yes seems like good idea. But for me in this case might not workout as Am planning to use this for subwoofer plateamp,So don't have the terminals and such.

Sreekanth, your layout looks very nice and compact. Did not check for correctness etc - will
leave that to the experts.
However, I am wondering how you would plan to mount the R33s - would they float a bit ?
In your layout, the R33s pass over the pads of the output transistors.

If you could check that'd be great too as no expert has stepped in to do it till now.

As with the resistors, They are given little oversized footprint just to make sure I can accommodate the big resistors (some of the local ones are) so shouldn't matter much but in case if it does then yes lift it a bit and solder.

Thanks again to you, yurik, and others who bothered to take time to respond.

Hello friends!
I need the gerber file of the power supply board for APEX PREAMP P30ZF
I have one for the preamplifier, but I don't have one for its power supply.
Please help urgently.
