If this is the right area for this:

1) Design/kit for a powered subwoofer

2) Project for an Isotek style mains purifier for my turntable and CD player

Design for powered subwoofer is on our list for World Designs. Needless to say it won't quite follow the standard commercial pathway for design. (No questions at this stage - wait for the article!)

David,

I used a 3 amp two stage Schafner filter type FN2080 from RS, 219-2971. Not cheap and I have no alternatives to compare it to but definitely an improvement for my transport/dac. I've also seen something on John Risch's site at http://www.geocities.com/jonrisch/surge.htm but have not tried it.

Sounds interesting. Me, I'd like to see some bipole push-push subs, or even dipoles with built-in active EQ but I suspect I'm in the minority there. Either that or, for fun, some TL types. A reduced version of Nelson Pass' El Pipe-O would be amusing, and dead-easy to build, even if it is a bit of a compromise compared to a 'proper' TL / QWR (whatever that might be!)

'Fraid the foregoing is beyond me. What surprises me, however, is that there has yet to be a mention of remotely controlled amps - volume only would be sufficient.

WAD did offer a motorised pot but nothing to drive it. A remote control could be a standard offering to fit any model of amplifier and I'm sure would prove a popular option. I'll certainly take one if they become available.
