I'm searching for any information you may have on a 6M-E5 'Magic Eye'
tube manufactured by 'Nippon Electric' and apparently only used in
Heathkit AJ-11S AM/FM Tuners circa 1962. Numerous Internet, phone
calls and e-mails have come up empty.

One of the very few Internet articles I did come across indicated that
the 6M-E5 'Eye Tube' was used in the AJ-11S for economy rather than
using then expensive meters. These tuners used two of these tubes, one
for AM and one for FM.

My 1970 NEC handbook has a 6M-E10, but no 6M-E5. It does list an EM5,
which is a dual section unit.

Have you got the pinout from the manual?

It should not be TOO hard to replace these with a 6E5, or whatever
magic eye the guys at AES have on sale today, but it may take some
repinning and change of resistor values.

I think heath may have had several tuners that used the 6M-E5. Two 6E5s
might not even fit in the Heath tuner I am thinking of, and you would have
to cut up the front panel to make them work, as well as building new
mounting brackets. The 6E5 is quite a bit larger than the 6M-E5.
