Dave strikes again!
I needed meter lamps for my SA-7700/TX-6700 combo. The 8v, 50ma lamps are no longer available. But, Dave worked with me to come up with a combination that produces very close to the original amount of light (6.3v, 100mA). While these must be wired in series rather than parallel, they work well enough to go up against the originals and compare nicely. Dave tried the lamps, and compared their light output to other meters he had available, then sent me several, at a nice price.
since these lamps are being operated at several percent lower voltage than their ratings, they should last for a very long time.
Thanks Dave...
