I came upon a London Audio show entry ticket from 1958. It's in stellar shape. On the back Peter Walker drew a phase splitter schematic and printed his name on it. I scanned it and sent it to a shop who rebuilds the speakers and he thinks it's legit. All the links I could find point to this one for QUAD - bit it doesn't work.

Can anyone tell me how I can reach the company or the QUAD family?

Hey everybody! I just joined. Need some advice for this turntable i bought. National Panasonic SL-18. The problem is, it's playing too slow. The pitch of the music is half a step lower (half a tone) than it should be. It's not my only turntable, i grabbed it cheap so i could play vinyl in both rooms. Apparently this turntable was unused when i bought it and it looks it. But yeh, i have a speed problem with it. So, is this model adjustable at all? I know of some local turntable specialists which i am going to visit soon but i thought in the meantime, i would ask for some advice online.

As I recall, you were very fond of the Tivoli PAL - the Henry Kloss designed AM/FM portable. Any particular reason you didn't do a comparison of that radio with the Music Hall RDR-1?

Regarding personal FM transmitters, I certainly agree that one needs to find a spot in the band with no strong adjacent stations. Whether one is, "..certain to find a nice empty spot on the FM dial.." without strong adjacent stations depends on location. In metropolitan Chicago, it's next to impossible.

Well, "Gnarls Barkley" was the last straw. A brilliant bit of work IMHO, but compressed to death, to the point where I can't turn it up to near where I'd like to; it's just too unpleasant.

So: Gnarls is available on vinyl. I own 600+ slabs of vinyl, but haven't bought new vinyl in many years. Is there more dynamic range on vinyl, or is it compressed also? Or does it vary from record to record?
