It was about the time to make a decent preamplifier for this audio amp. It's a two channel op amp circuit with in a non-inverting mode, with simple 1st order RC filters. Opamps have fixed gain of 6dB (Av=2) each, and the level is adjusted by simple potentiometer.

Since the circuit is limited to 1.5A anyway, I would use a LM317 regulator which reduces the parts count, is good for 1.5A (with internal limiting at about 1.8A) and also includes internal overtemperature protection etc. The LM317 doesn't need a lot of overhead, maybe 1.5v to 2v overhead so...
