just can't do that. Way cool. I never tried it with cannabis, but probably even better. Other than that memory, and certain trade-offs at big Rf power, I'll say I no longer encourage the glowing bulbs for most things.

Way, way back I was listening in the background to an old Teak amp one day when I thought that it sounded a bit distorted. Went over to look at the chassis and saw one of the valves in the output stage with it's anode glowing red! Hmmm, seems it was conducting just a little more than it was supposed to do due to a biasing component failure. A couple of minutes later and some work with a soldering iron and the sound was fine again. That chassis went on forever on that same valve. > Solid state amps just can't do that. Way cool.

They soon go legs up if you apply too much voltage or current which valves would just shrug off. > Other than that memory, and certain trade-offs at big Rf power, I'll say I > no longer encourage the glowing bulbs for most things. They certainly still held their own in high power RF stages but I wouldn't go out of my way to build something out of them now. As for conductive surfaces for benches and the like, RS Components used to sell a static conducting matting by the square yard that you could order. It was a yellow and about 1/8" thick flexible dense rubberized material. We covered our benches and floor around our workplaces and had the press-stud fittings riveted to them so you could clip your earthing strap to it. It was very hard waring and coped well with molten solder dripping onto it. I believe I still have a sheet of it somewhere in the garage. 73 Steve -- Steve Rooke - ZL3TUV & G8KVD A man with one clock knows what time it is; A man with two clocks is never quite sure.

It's a single 3W white led, at the end of a 55cm long (that's 20" for the imperialists amongst us) "swan-neck". I use one for my small CNC-mill: http://ing.dk/uploads/society/content/232.png It's called "JAN SJÖ" here, not sure if they use that name in other geographies. Highly recommended. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.

ful little LED lamp for the worktable. > > It's a single 3W white led, at the end of a 55cm long (that's 20" for > the imperialists amongst us) "swan-neck". LED lamps... the one thing I keep being annoyed about is the aspect of having three peaks of relative narrow spectrums rather than the normal continuous spectrum mainly being that of the temperature signature. Anyone out there looking at the frequency spectrum of these low-energy lamps? Colour response from few-spike lamps is not really the same than from continuous spectrums. > I use one for my small CNC-mill: > > http://ing.dk/uploads/society/content/232.png > > It's called "JAN SJÖ" here, not sure if they use that name in other > geographies. IKEA has a habit of giving all their products Swedish names for their products... worldwide. It's part of their trademark so to speak. Cheers, Magnus
