    The Humble #53 Lamp

    Post by Peter W. on Thu Jan 31, 2019 8:43 am

    Guys and Gals:

    Once upon a time with a Radio Shack on every other corner and in every mall, the matter of indicator lamps for our beloved Dynaco products was never an issue. #47s for the 6.3 V applications, and #53 for the PAS in various of its incarnations. Well, guess what:

    Pep Boys was out of stock. The counterman stated that it could be 'ordered', and would take three days.
    Mouser no longer stocks the #53.
    1000 Bulbs lists it, but has none in stock.
    Digikey does not stock it.
    Several other suppliers list them as obsolete.

    Back in the day, I drove VWs, and remembered that the #53 was a common indicator lamp. So, off to Advance Auto, the local shop showing them in stock. They were not in the floor display, which went from #37 to #57. The counterman went 'into the back' and came out with two two-packs, carefully explaining that these were the last two in stock, and none were on-order, nor were they listed as 'active' part numbers. Of course, I bought both.

    What is special about the #53? It is a 14.4 V @ 1.7 watt round bulb.

    Now, not to be alarmist, as any number of automotive supply houses stock these beasts, typically in 10-packs. But, if you want one *right now*, I do suggest you call your nearest automotive supply and see if they have them, or can get them. And keep a spare as well (2-pack). As Dynaco stuff tends to accumulate like lint around me. I bought both at Advance.

    Ebay will list a number of bulbs and some of them will cross to the #53. The ones in the link below are for autos listing a 12 V rating. They should work but may not last as they look cheap. If they die early at least you have a quantity of them to try.

    Here is the problem:

    The lamps in the link are LED (DC-Only), which for automotive use is fine.
    The #53 in the PAS runs at (approximately) 11 V AC, directly off the bias winding from the transformer.
    I suspect that Hafler used the #53 as it would have a very nearly indefinite life at 11 V.

    Note that the #47 in the SCA also runs directly on AC.

    I always learn something here at the forum. Thank you - I appreciate it.

    The following link should work fine for the #47 type. I used these in my last SCA 35 rebuild. https://www.ebay.com/itm/47-Pinball-Arcade-Machine-Playfield-Light-Bulb-Lamps-6-3V-Set-of-50/222093793794?hash=item33b5d25a02:g:--AAAOSw2bFcOjbw:rk:2🇵🇫1&frcectupt=true

    As for the #53 these are not the LED type. Agreed? https://www.ebay.com/itm/10x-53-Light-Bulb-Miniature-Gauge-Cluster-Instrument-Panel-12v-T3-1-4-BA9S-Lot/262702752063?hash=item3d2a4de13f:g:oAMAAOSwcUBYGpgl:rk:1🇵🇫1&frcectupt=true

    Reasonable?

    For whatever it's worth....
    I found these on Amazon.
    https://www.amazon.com/gp/product/B07DK82GGC

    They're not really red. They're closer to tube heater color than anything I've found.
    They are plain old 120 AC.
    I put one in my st120 as well as the sp14. (I like things to match)

    I may go back later and put a resistor in to tone it down a notch.
    (holy reflections batman)
