Acoustical Mfg Co The Quad II Amplifier in overall very good cosmetic condition, as shown. Upon initial power up, we noticed that the current draw was increasing substantially, so we shut down the unit and no further testing was performed. Assuming at least the PS caps will need replacing. NOTE: This is a vintage audio item that may need basic servicing before using it on a daily basis. 7x14x5, 20 lbs RC3
