A40 Part Substitutions

I was a senior in high school the year the A40 article was published. I had forgotten how wonderful recorded music can sound. Here are a few photos of my completed project. I incorporated a trim pot for R11 so that I could adjust the bias due to not using the original ouchput devices. I also incorporated CRC filtering in the power supply. It's biased to 40 watts and clips at about 82 due to the extra 10 volts on each rail. Thanks for all of your support and contributions to the DIY community. Regards,
