Paul, poster Paully, was down a couple of weekends ago.  We listened to Fleetwood Mac's Rumours.  It sounded slow to both of us.

I have a strobe disk but no light to produce the stroboscopic effect short of bringing a fluorescent lamp from my workshop.

Any suggestions for an easy strobe light for my TT?

Thanks in advance,

Just pick up a cheap neon bulb from RS.

Neon seems to be the preferred lamp for any table I've ever seen with a built-in strobe.

Somewhere I own a neon test lamp.  I don't know where.  Maybe I should get another and put a plug on it.  When I do the first one will reappear.

Any light will work, even an incandescent bulb has a 60hz flicker. Or try one of those new fangled CFL's...John

The CFLs seem to be running at a higher frequency to me, at least the ones I've got.  I haven't dissected one yet, but I get the impression that there is a little electronic "ballast" in the base, which tends to make noise somewhere in the several thousands of Hertz.

Of course, I doubt that they all are the same.

I have a high intensity lamp above the TT now.  I'll try an incandescent light bulb.

I brought around a desk lamp and checked with the VPI strobe disk.  It was about 1.5% slow.

Then I lugged the VPI PLC up from my work room and tweaked till it looked good.  

It sounds better now.  Strangely, with increased speed the bass seems tighter and more present.
