Re: Hum issues on transformer output preamp

It could be hum on the signal line Andy which would be there floating output or not.
Quad 405-2 had a curious variety of earthing arrangements due I think to Quad changing ranges in the mid 80's and...

Re: JR149 speakers

Re: Feedback

Morning Greg, Yes it's difficult to remember sounds across a period of days. There will also have been a volume/sensitivity change and anticipation/expectations involved.

Your friend may well be...

Re: Crossover components rolling ?

The (now) Vishay 1813 range of axial polyesters is good for many speakers. They have other ranges of higher voltages but the 63V is pretty much enough for many speakers. Polyester and polypropylene...

Hi Greg, totally on-topic :). I can't remember anyone posting about lowering fb in Kit6550 so good to hear how it went. Yes the Sowter's are very good and perhaps need less fb than other TXs due to...

Re: Swapping out valves

The logic would have been to break a hum loop in a particular system where the system was being earthed more than once causing hum.

The important thing in every system is to ensure all units are...

Re: Feedback

Hi Andy, it's a recent Quad power amp, son of 909, grandson of 707, gt grandson of 606 Mk2 lol, it's the same amp made in China.

Only guessing it might stand for (if it is an acronym) Quad Stereo...

Re: Feedback

Hi Stuart, QSP is very nice, I've had a 606 mk2 and 34 preamp the last 3 or 4 years in the main system. The 33/405 was my first serious amp too, back in the late 70's. I got another a few years ago...

Re: JR149 speakers

Well these are back together again and I've had several good listens over the weekend.

I re-capped them with Vishay polyesters which I've used for coupling before and they sound very nice to me.

Re: JR149 speakers

Hi Bob and Phil,

Yes they are what they are but it's been a long time since I heard them so it will still be fun.

They're for a vintage system, backs against the wall in a smaller room, so no...

JR149 speakers

Hi all, anyone had these? I chanced upon a pair going locally the other day. Not cheap or in particularly good condition but one owner and looked like they'd spent the last 40 years in the dry which...

Re: PLZ pre-preamp

Hi Andy,

That little circuit looks easy to build. Have you heard one? One of my earliest projects was a single transistor (BC109?) head amp circuit in one of the hifi mags of the day powered by a...

Re: PLZ pre-preamp

Yes it's a MC head amp, designed to provide the correct cart loading and increase MC output to MM level, and then be plugged into a MM RIAA phono input.

Re: PLZ pre-preamp

Hi Stuart,

Just replace the caps and batteries then and give it a listen. Without a circuit diagram and set-up info there's not a lot more you can do.

If it looks fairly simple you could try...

Re: WDVA88 XL What speakers are you using?

Hi Lee, yes, I'd get the TT set up and also listen to the other speakers and try different positioning. You'll see the MA's don't actually specify frequency response to any tolerance limits or...

Re: WDVA88 XL What speakers are you using?

Hi Lee, there are many here who have or had your amp, me included, but I doubt many will have heard it with your speakers. What is it you feel doesn't quite work?
