Info Requested 6M-E5 "Magic Eye" tube |
|
|
Hello Group
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.
I have available a 37K scan of our sole survivor.
Any info or advice would be greatly appreciated.
Thank You
Kip

Its very common in Japanese domestic radios and other electronic gear. |
They used them well into the 60s'. You can find plenty of info on the
Japanese sites on the web, just run them thru a translator like Altavista.
Here's a German site thats self-explanatory.

Does this have a red dot in the center? There was a special ^E5 used in
Japan called 6E5R but have never seen one here,.

I may be mistaken, but I believe the 6EM5 is the miniature version of
the 6E5, and was also designated the 6E5M by some manufacturers. That
would be consistent with the 6E5R nomenclature, the "R" indicating a
red dot. |

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.

Yes, but do you have the relevant part of the schematic?

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.

Yep, that's one fine site for tube lovers: over 1 GB of hiQ photo's &

It's top view just like a full size 6E5, I don't remember if the base was
a 9-pin mini, or something slightly special, I seem to remember something
odd about the base.

I don't know about that, but now that I think about it, the base must have
fit a standard 9-pin mini socket because I didn't have any problems
pluging it into my tube tester. IIRC even though the tubes had pins like
a 9-pin mini they had a black bakelite base like most octal or older
tubes.

Looks like it's a 7-pin miniature pinout, but on a big fat plastic base
so you may actually be able to shoehorn an octal magic eye tube in there.
Call AES and see what kinds of magic eye tubes they have in stock that
will physically fit into place and have 6V filaments.
The electronic stuff is easy. The schematic on that web site basically tells
you all you need to know; where the plate, filament, grid and deflection pins
are and what voltages they need to see. With this you can adapt just about
any magic eye tube if you can make it physically fit.

It is a standard 7 pin miniature pin spacing on the base. I have
posted a scan of a 6M-E10 (same size) alongside a 1629 for comparison.
The 1629 is pretty much the same size as the standard 6Volt heater
Eye-tubes.
The picture is on alt.binaries.pictures.radio
