Thanks for this Mr. Mile. I think I can make use of multiple TB3 PCBs to build TB7. Between, do u have the scheme of 10 band equalizer, may be TB10?

Thank you

My ax14

After many years, my ax14 alive. Sound very good. Deep bass and clear at high.. Picture just for testing only. Will build new board.

To what is the top-right GND connected to?

May be used for Returns from amp out and to speaker if required...

Also provided one extra return (GND) at DC Output for speaker ground so that from amp board need to take speaker (+) alone to protection board...

thank you mine is same too but bass is not good enough and if i dont connect volume pot 5k or 10k there is too much noise coming to output.

maybe i need check prassi sch with apex sch so i can see the what is different.

thank you again for answer..

I finally started my build. Initially wanted to build the FH9, but then changed to the NX14. Started populating it last night. Then found out I ran out of 220r 1/4 watt resistors. Got some at work today and going to finish it off now. When this build is done Im going to start the FH9, and then the much praised A40.


My AX14 so far

Anybody care to share the last working pcb layout of the P30 preamp?
