Stewart Palmen,Youtube

"Many thanks for this and your other excellent videos"

Ian Watkin, Youtube

"Thank you for an excellent description of the Mazurka. As a teenager i saved up for quite some time and bought a brand new mono Mazurka. After about 6 months i invested in the second channel and seperate matching speaker unit, what an improvement !! It was my pride and joy. I am retired now but those two units are still iin mint condition sealed up in my loft. I have recently considered restoring them electrically. So thank you again."

"Very good info and summary thank you "

"Brilliant. I have a stock of Quad II's that I am bringing back from the grave. 10 or 15 years ago they were the best I have ever heard. But now they need attention. These insights are pure gold!!!"

Mark Cornwell, Youtube

"Very interesting video and information. My dad had this equipment in the 60s including the decoder for stereo fm, also the am tuner which if my memory serves me right was available as either medium long short and medium short short waves and dad had the latter. Quad service was brilliant back then. There was a problem with one of the units out of warranty we turned up with it and the engineer said leave it with us and come back after lunch which we did and it was ready repaired and at no charge. Dad moved on to 33 303 fm2 which I still use along with my own 33 303 and 2x fm3 but wish he had also kept the valve set up too."

Barry Thompson, Youtube.

"Very good video Sir.. You explained the schematic of those beautiful amplifier's as well as one can. I had never heard of the brand before (maybe they weren't exported to the U.S. in great quantities?), but they are extremely well built, the company obviously took much pride in their products."

Bucyrus Erie 12, Youtube.

"Many thanks for the video, very interesting."
