The earliest guitar amp I worked on was a small Ace Tone, back in the 1970s. My neighbor bought it, not working and asked me to get it running. This was apparently from a foreign country, probably Mexico because at was rated for 230 VAC. It had two tubes, a 12AX7 and a 12AU7, that had been swapped around which caused them to not work. Once I fixed that I had to get it to work on 120VAC. I made a voltage booster by connecting two Radio Shack transformers, each having a secondary of 18VAC, back to back and boosting the 120VAC to 240VAC. It worked okay!
But I have never heard of the Ace Tone name since that time way back in the ’70s.

It’s loud a few blocks away where people live.

The TA7642 (AKA ZN414) is a crippled IC. Because it has only 3 leads it can’t act like a normal IC that has an input, output, power and ground. The output has to come out of the power supply pin. It’s limited to only 2 or so volts. As a result this IC can’t have much gain because the output is on the power to the input amplifier! How stupid can you get?? If the output was not inverted then the output would cause the input to oscillate. If the output was inverted, then it cancels the input signal and the output is weak.
So instead of using this IC you just use 1 or more transistors to do the job properly and make a real radio.
