wiki: Neon

particularly annoying

I can't remember it being available from our central spares either, (otherwise I would remember liberating a tin or two), perhaps we got it with petty cash.

A random thought has just crossed my mind, we used to go through gallons of Granada branded Joynes Waxless Polish for cabinets. Unbelievably, a quick Google shows the stuff is still available, but now in sensible shaped plastic bottles. In the '70s it came in a flat medicine style glass bottle and I must have spilt more than I actually used.

We had a French Polisher called Ted that used to come round all the depots in the area. Quite a character, and what he couldn't do with wood.

Thanks for the reminder (!) I don't remember the neon for squelching the line osc, but this exchange would be incomplete without mention of the EHT shunt regulator, PD500. I suppose they glowed like a neon in operation; not that anyone with half a brain would be looking of course.

Ah the days of valves..!

I never forget seeing some turkey's valve amp's anodes lighting up like a Christmas tree when he hit a power chord on his Farfisa..

As I recall the neon stabiliser valves (such as the 150B2 mentioned elsewhe= re in this thread) could pass several milliamps, in some cases some 10s of = milliamps; the regulated power supply I still have somewhere uses them as a= voltage reference controlling a series pass 12E1 for higher current output= , but that's definitely a piece of bench testgear and not something that wo= uld be designed into consumer electronics.

Derfintely milliamps for the bigger ones.

Mullard 90C1 rated at something like 100V 40 mA. So a 4W device,.

FRENCH POLISHER!

You had a better class of customer than we at Rumbelows then.

We did have one engineer who would thouroughly clean the vomit, chip grease and other crud from half the set.

We did have some foaming stuff for sets that hit the workshop though. It had a soectacular effect on the tobacco tar on the CRT.

Just a little befoe my time. I saw the odd one or two "towers". I imagine they were all used in dual standards.

The day's of lead underpants, degauss coils and daylight references.

Happy times!

Sorry, I should have been a little more clear. The indicator lamps are microamps and therefore of little use as a stabiliser.

Neons were and probably still are used for oscillator stabilisation and those I am familiar with will sink around 10mA or so.
