Quad 44 Pre Amplifier Sought After Late Charcoal Grey Model + 500 Upgrades. I purchased this, and as most people understand, due to the age of these pre amps, they generally need capacitors replacing and servicing. I went the full hog with this one and had the Red Hill Audio stage 3 upgrade done during the service. This cost 500. It totally transformed the pre amp. You will see from the pictures that it has an external power supply that is part of the upgrade. Just around lock down, I sent all my quad equipment to Amplabs electronics, and it came back with a clean bill of health. It required no work. He did some work on my other items. Excellent service! I have hung on to this as it sounds great, but I dont use it. I have decided to let someone else enjoy it and move it on. Its fully tested and in good working condition.

QUAD VA-ONE + (PLUS) All Tube Integrated Amp MINTComplete set of Gold Lion replacement tubes, about $500 retail worth You can own an all tube integrated amp that sounds amazing. The ONLY one like it.Ive had it about 3 years, bought from Crutchfield, and I am moving up to Quad separates. Im also providing a set of replacement Gold Lion tubes bought from Upscale Audio. See pics for details on what is included. NOTE: About a month ago, it gave me a lot of distortion. I powered down, and restarted and it was fine. I did some research but couldnt come up with a reason why this happened. No blemishes, sounds great, looks great, and this is a rare unit. All tube sound with BlueTooth, and three digital ins, and an analog in as well. 15W booms out of the speaker connects and drives a range of speakers. This is 15W of TUBE power, not wimpy solid state power.
