Great American Sound Ampzilla 500 with Rack Handles and LED Output Meters. 250 watts/ch into 8ohms and 500 watts/ch into 4 ohms. What you are viewing here is the Ampzilla 500 second generation prototype amplifier. The LED meters work perfectly and are quite neat. I confirmed the authenticity of this amplifier with the last owner of GAS, Great American Sound. This amp was to be the next generation Ampzilla 500 and before this amp went to production, they closed the doors to Great American Sound forever. This amp was also featured in a Playboy Electronics Edition, which I will also be including in this sale(and is also in great condition... especially for a magazine from 1981). I too confirmed with the owner of GAS that this very amp is the amp featured in the Playboy. The amp has been completely rebuilt by Mike B of Gasaudio.net. The stock circuitry has remained unchanged to keep its purity. I will include a receipt of all work done to this amplifier and it will also include a one year warranty on the work done. This amp sounds fantastic. I find this amplifier to a be a piece of Great American Sound history. Feel free to contact me if you have any questions. Please add 3% for paypal.
