I was missing one on my Creech. In the end I just got a standard mini bulb holder from somewhere (Andy or Phil I think) and then soldered on two bits of wire snipped from a resistor at right angles to make it fit perfectly. It’s indistinguishable from the real thing unless you look really closely. Cost almost nothing.
If you want a pic when I am back in the U.K. next week let me know!
We got some..!!!..(used of course as these have been unobtainable for yonks)...are yours brown or black?.......I will check how many....and edit when I find them!....k
