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).
Cool! That's good to know!
I'm not aware yet of anyone actually having tried the CM7370
instead of the OL-1.
I did some replacement lights PC boards for the 8/i, since
they seem to get crapped up when you solder and desolder on
them (bad adhesion on the traces). The replacements have a
provision for optional sockets and series resistors, so you
can substitute OL-2 or whatever 15V-or-less bulb you happen
to have on hand. (Even LEDs, if you really must.) I have
several more of the PCBs, if folks need them. I also have
a couple of switches PCBs, if yours has been trashed. (You'll
need to salvage the switches from somewhere though, as they
are unobtainium.)
I do have one working 8/i panel that I completely rebuilt with
the replacement PCBs and OL-2 bulbs + resistors instead of the
original OL-1.

lamps at other than their nominal ratings can be found here:

That's a nice write-up. It used to be available on the
Oshino site, and I have it saved from there.
