Rob’s flip-top radio build

“I have now added a tone circuit to the amp, a switchable R3 resistor which gives a little more brightness and compression, and a negative feedback switch that goes from stock 22k to 100k. It’s looking and sounding great. I do wonder if a lower negative feedback amount say 56k might sound subjectively ‘better’ than 100k. Or maybe an even higher value would work better?!
“Thanks again for producing a great kit and fantastic instructions. It’s been a really enjoyable experience and so rewarding to play through an amp I’ve built. I can see a P1800 in my future. I fancy doing one of those in a 3×10 combo with the chassis mounted on the side of the enclosure, a bit like the toneking falcon, just with more speakers.”
