Having restored a few Seeburg Sc1 wallbox’s now, I am only to aware of how costly & difficult to buy (here in the UK) the #19 lamps that are used. Have normally had to order them from the Netherlands.
After having a chat with an acquaintance I decided to look into the possibility of substituting the # 19 lamps With LED’s.
http://www.pinball-led.co.uk specialise in LED’s There #555 range of led’s are both Bi polarity and also designed to work on 6.3 volts & according to them will work on any voltage between 3.5 – 8 volts. They come in a range of colours two types of white, warm & cool, and even colour changing and cost from about 30 pence each.
So I have ordered a few of these to give them a try, when I get chance I will see how they look and if they work well I will post a photo.
When I saw the led’s I wondered how the anode & cathode were identified, as they don’t have the unequal pair of legs like normal led’s
In fact they look very similar to a #501 automotive lamp, so I emailed the company and asked, they assured me that they were bi polarity. As to weather they can be used for AC voltages or not I did not ask. I suppose I should have.
I will fire off an email to them, hopefully they will have been delivered by the time I get home.
