QuickSilver Tube Amplifiers; Excellent condition and sounding pair of QuickSilver Silver Series 90 watt KT88 mono blocks for sale. They are as beautiful sounding now if not better than when first purchased. I am the second owner, my older brother the first. These amps could not have been better cared for as both of us are fanatics when it comes to the care of our equipment! He sold them to me when he bought traded up his MGIIIa’s for a pair of MG20s, and found them not powerful enough to drive the 20s. I first used them with a pair Advent 2 way spks. I eventually bought his MGIIIa’s (which also are for sale) and used them as the mid, treble amps in a bi-amp system for the Maggie’s. I am now purchasing a par of MG20.0’s (yes from my brother, he’s upgrading to the MG20.7’s) and need larger amplifiers. I’m not allowed to keep everything so they two have to go, you know the wife. I truly hate to see them go as they have brought me and my family many, many hours of sonic enjoyment. They have always been kept covered when not in use and are in beautiful cosmetic condition. They along with the rest of my system were always powered from a power conditioner and physically disconnected from house power via a 30 amp industrial grade mtr. disconnect switch when not in use. This is to prevent damage from lighting strikes and power interruptions. Other than tube replacement these have always been tried and true performers without any need of attention other than the factory recommended bias adjustment.
Included are the bias meters held in place by ‘blue tack” so no alteration or damage was done to chassis. Original packaging and paperwork also included. The power switches have been bypassed and the original 110 power lamp cord and plugs replaced with hospital grade plugs and Professional Audio 7Layers Triple Screen Power Cable. I have contacted Mike Sanders, QuickSilver Co. owner a few times over the years regarding available maint or upgrades and there are none.
