Default Griffin Transformer for Philips Spectral Lamps

Hi all

I don't really know what this is, though a bit of a google gives some idea. I had thought the case was rather nice, but if someone here has a use for it then I won't break it. £5 for Christian Aid plus (expensive - this is heavy) post at cost? And if anyone can enlighten (boom boom) me about it, that would be interesting too.

cheers
Mark

It would be a good box for a power supply for military receivers like the R1155 and HRO.

Hi Mark, the transformer inside will be a special type used to both start and control lamp current. Similar in many ways to the ones used with sodium and other street lamps.

What are the case dimensions, Mark? Perhaps would be useful for an isolation Tx I acquired a while ago. Thanks, Graham

School lab equipment for firing up a small low pressure sodium lamp for example for optical experiments/demonstrations like Young's slits or resolving the two-line spectrum.

Later became Griffin & George

Thank you Ed and David. I thought it might be something like that - I don't have a lamp to try it with, but there it is.

I have a small lamp type device which could be a Philips 4348.

As in this type http://lampes-et-tubes.info/dlsp/dl077.php

But the coating is black and not silver and there is no additional wrapping so may not be original etc. it would suggest a 50Volt supply at 83mA so your transformer may be for a bigger device.

You are welcome to try the lamp if wanted.

Thanks Adrian...but I need to move some things on or I'll get shot. Are you sure you wouldn't like to try it?

I am trying to get cracking with the last pile of things I was given to sell for charity when our lab was moved a while ago. My wife has been forbearing, but I think has run out of patience with me, which is fair enough. I'm also hoping not to wear out my welcome here, where folks have been very generous in supporting these efforts over the years!

cheers
Mark

Isn't that panel-mounted mains jack in the photo with the bottle of Banks's worth a small fortune?

looks like a belling-lee connector, they also used them on the motor connector on Griffin van de graaf generator speed controllers

OK, dimensions look good, thanks Mark, so I'll place a bid for the case only, please. Will definitely stand aside for anyone who wants it complete with the transformer, so please let it run as long as you dare. Also wouldn't need the connector that Kevin has highlighted, so happy for that to be removed and sold separately.
(Might be passing through Manchester just before Easter, but would be on a train, thus postage most likely required.)
Cheers, Graham

OK Graham - the case is yours unless someone wants the whole thing. Just the case won't weigh much, if you want to collect it as you are coming through, but I don't suppose it'll cost so very much to post either. I'll leave it a bit more to see if anyone wants it whole.

Julian - that connector is not what you think it is (I am sure Kevin has it right) - but I do have some 3 pin 22mm Bulgin mains plugs and sockets if anyone wants to give a load of money to a good cause instead of into an online dealer's pocket
