Re: tektronix 7S14 batteries and time base question

It is a shame that the original spacing for the batteries was so tight. I
realize the need to keep the leads short, but it makes it difficult to
replace the Mercury cells in such a tight spot. It would be nice if
someone could come up with a tiny hybrid fix that could be dropped into the
small footprint.

Efficiency as measured by voltage transfer, it would be interesting to
compare power transfer efficiency. With 20mA on the driven LED is it
possible to get even a few microamps of output current?
