PCB's ordered. I want to try out of just out sheer nostalgia, because I had begun my amp DIYA journey through APEX LM3886.
If anyone wants to book PCB, contact me through PM. I will have total 10 available, 8 can be spared. Pl note it will be shipped as soon as received and not after testing. After all its DIYA, so better to have fun while it lasts!.

All 8 PCB's interest booked by people (in less than 1.5 hours!). D@mn, I could have ordered some extras if i had known before , but hats off to Mr. Mile for a design thats so much appreciated, that people would like to try even untested.
Mr. Mile, dont know how you are able to produce these designs !!

Are the voltage regulators to power the opamps?
Which opamps are you planning to use?
What voltages can they accept?
The chipamps do not need any voltage regulators.

Apex, Prasi,

Great work once again. I have an LM3875 premium kit and an LM4780 classic kit from audiosector I bought quite some time ago. This means I have 2 chips of each, parts, and the pcb's.

My question is: Can these chips be used with your super gainclone pcb with some minor changes or are we talking about completely different animals. My gut tells me no, it is not that easy, and to go build the stock kits, enjoy them, and then modify, or build something else in the future.

Just inquiring in case.......

Myles

yes you could but supply voltage should be less than or equal to 30V.
