Hello, A short while ago I sold an adaptor kit, marked B1921 and made by Osram. It had the adaptor for an A1/193 bulb plus two A1/215 lamps and a loading tool for fitting these small lamps. At the time I didn't realise what this was for ........! Some time later I discovered it was for an Eumig P8 projector - one of several that I had inherited - and I could have used it! I carefully measured the height of the lamp filament and noted the orientation of that filament to the base pins. I took the old 193 lamp, wrapped it in layers of paper and very carefully crushed the glass. I then had a lamp base with two wires protruding from it. I took an almost circular base that was also in the inherited items, sleeved the wires with heat resisting tube, twice over, and then used a resin cement -something like Araldite - to fix it all together. I left the base to cure for 48 hours. I was apprehensive when I fitted this adaptor into the projector - it fitted perfectly! I used a cardboard sleeve and tweezers (spring loaded ones that only open when squeezed hard) to fit the lamp. Lamp filament fitted correctly at right height and orientation. I powered up the projector, left it running for a while - without film - to see how hot things got. No apparent problems on that front. Finally, I took a short reel of scrap 8mm film and ran it through the projector. It worked fine and obviously was running cooler than the original lamp. I am pleased with the finished item - it cost about 30 minutes of time to make. I'm over 80 but fairly confident with the old 'Weller' soldering iron that I use ...... . Have a go yourself - lamp bases are readily available in the market. Phyllis
