    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.

    Cheers Scudie

    But… Don’t the #19 bulbs run on 12 volts AC?

    I put a my voltmeter a cross one of mine and got 6.8v on all three of the instruction window lamps.

    Oh… I haven’t tested voltages across those. Look forward to hearing how they work out for you. I haven’t heard of bi-polar LEDs before.  Are they supposed to work on AC current too?

    I believe the two that light up the program pages are in series each getting about 12 volts.

    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.

    I suppose it would be simple enough to add a diode and capacitor in front of each LED to convert the AC to DC.

    Just had an email from the LED people they tell me that they are OK for A/C power supply’s .

    Cheers Scudie
