OL-1 substitute

Has anyone tried the currently-available CM7370 in an 8/I or RK05? This bulb is suggested as a substitute for the OL-1 on Vince's web page. The suggested substitute for the OL-2, the CM7371, works wonderfully in an 8/E. They are plenty bright, and they will last longer running at undervoltage. An 8/E that I received in working condition arrived with a full complement of CM7371 installed by its previous owner (a machine shop). I suppose the big issue is matching the brighness. You probably don't want to substitute the bulbs piecemeal, and repeatedly unsoldering/soldering soldered-in bulbs is damaging for the circuit board. Best to replace them all at once, or install socket pins (scavenged from machined-pin IC sockets) as found in the 8/E. Some technical information regarding operating incandescent lamps at other than their nominal ratings can be found here: http://www.wamcoinc.com/Oshino/Oshino_lamps-Overview.htm --Bill
