Warped LP’s

 Has anyone found a reliable and safe way to flatten warped and dished LP’s? I have four albums that I would like to recover. I’m guessing that between two sheets of glass, but for how long and how much weight if any would be required MORE

FUNK / PINK TRIANGLE & BREUER – a few observations

  Howard – one of…no, the best turntable I ever heard was a special fully funked LP12. Sure it sat on a mountain of Mana, and was part of an awesome system…but it really out-shone the original modified (Ninja) LP12. So..if the Funk Firm could transform a Sondek like that, surely their own decks would […]

JBL: I have a pair of JBL L100 Century loudspeakers. They claim they are bookshelf size. 37Kg and big. Are they kidding?

Howard, I have a pair of JBL L100 Century speakers. They claim they are bookshelf size. 37Kg and big. Are they kidding? First – 37Kg per pair, not each! Well, sort of. Blame JBL’s over-enthusiastic marketing department in the 1970s and the studio environment from which these speakers, the domestic version of the JBL Studio […]

COLIN WONFOR: Accurate & cheap capacitance meters – are there any?

Dear Colin, Accurate & cheap capacitance meters – are there any? Have decided a capacitance meter will come in handy for taking some of the ‘guess work’ out of cartridge loading, in terms of being able to measure the real-world capacitance if my phono cable/head shell wires/connectors together. Only problem is one of budget :/ […]

COLIN WONFOR: When/why did capacitor value standards change?

Dear Colin, a question which has been nagging away for a few days now: why were capacitor value ‘standards’ changed around early 70s, and why such seemingly arbitrary numbers? In my Quad 33/303 there’s several electrolytic caps featuring values such as 2uF, 12uF, 25uF, 50uF, 100uF….. When (and why) were values changed to 10uF, 22uF, […]

COLIN WONFOR: Sanyo Oscon

Dear Colin, Solid organic polymer capacitors such as the Sanyo Oscon series have a very good reputation for digital decoupling and I’d like to use some when refurbishing an old CD player of mine as I’ve got plenty in my parts stash. Before I go fitting any I’ve got a couple of questions:  1)   A […]

COLIN WONFOR: 4-Pin DIN plugs to construct an interconnect for a Quad 33/303

Dear Colin, I’ve ordered a pair of 4-Pin DIN plugs to construct an interconnect for a Quad 33/303 system. Do both the channels need to be individually shielded, or is crosstalk not an issue here, and one could use something like this with just an overall shield? http://www.van-damme.com/14.html Failing that, can you recommend a really […]

MERIDIAN: Their ultra-rare 107 power amp and … a powerfully incontinent white dove

Q: Gentlemen, whatever happened to the Boothroyd-Stuart ‘Orpheus’ pre and power amp? Did they ever make into production? The preamp was a gorgeous looking precursor to the ‘rainbow’ Lecson pre. Very ’70s (should suit André) with a Nextel suede finish. Can’t find an image, but it had the sort of design aesthetics that would, I’m […]
