For anything else... Well, the problem is - I likely could recommend some stuff but the information you give is quite scarce. You just state that it should be about 10 - 20 watts and pristine clean (not an easy equation by the way). That's not a very informative description. Do you only need a power amp or do you need a preamp as well? What about features? Tone controls (if yes, what kind), loops, limiters, feedback suppression etc? Overrall simplicity? Can you work from a schematic or do you need PCB layouts as well? Give us something to work on...
Thanks for the response.
I was thinking of a fairly simple amp involving preamp, poweramp and passive tone controls. I don't think I need any loops or limiters and hadn't even thought of feedback supression. Overall something fairly simple. I can read schematics, and studies engineering 20 years ago, but am just a hobbiest. Yes, I can work from a schematic (at least the less complicated ones) and prefer that for simple point to point wiring.
The .5 and 1 watt amps I have built don't have enough power. On the other hand years ago I bought a big old 100 watt Fender (thinking I needed that to emulate some people's sound) and that was WAY too loud. I was thinking that sincle wattage is logarithmic something in the middle (~10 watts) might be suitable. I just want to avoid the fender situation where you are trying to find a nice volume level somewhere between 0 and 1!
Teemuk, you mentioned the LM3886. Are there any good fairly simple schematics out there for a preamp, poweramp, tone control amp using this chip?
Thanks,
Craig
