Can anyone tell me in which magazines these modifications appeared? (For that matter, does anyone remember that far back?) I would also appreciate any information on the effectiveness of these modifications. I have a modification for the Stereo 80 amplifier to makes its driver stage a little more durable if anyone is interested. Please use the mail. Gil houxo!bristol
