circuit sounds good but needs improvement.
I m very happy if u share ur experience for this circuit make good to better
Regarde GPS TURNA
PCB design or what?
The schematic
poor filters, poor drive, input without buffer.
This is the FC-28 Rev.2 Mono Tone Control
working at single Power supply 12-24VDC

Is this one side PCB?
Hey, that simple tone control basically works fine, just 2 details:PCB design or what?
1) remove the 471 capacitor across half treble tone control, it´s wrong, it kills treble and makes Treble pot action unsymmetrical.
2) yes, it needs to be driven from a relatively low impedance, but any Op Amp stage before it will do fine, a high impedance buffer is not necessary unless you want to build it inside its own cabinet, with its own power supply, as a "Universal" type tone control, to be used anywhere, no matter what.
But to integrate it into an existing Preamp, fine.
3) simple as it looks, tone control slopes are 6dB/oct ... exact same as on 99.999% of tone controls out there.
Simple is beautiful

yes one side only

Thanks JMFahey for tone control,
What is your suggestion for post #24 (100w ).

For high power I find it best to use a tried and true, built by many high power amplifier, rather than adding a ton of transistors to a smaller one.Thanks JMFahey for tone control,

Search among Apex´s designs, he has some very good ones.
Another point is that I would never build a protection less amp for public/portable duty such as PA or DJ , sooner or later you will blow it (by mistake of course, poor connection) and/or burn expensive speakers.
Home duty is different because you can use terminals, both at amp and speaker, wire them *once* and leave the installation fixed.

Hello JHFahey, Yes you are absolutely right Apex have so many good desiges. Mile slavkovic has big knowledge about amplifier, so I going to his famous amplifier AX-11 with simple tone controller.
