It's a octal base, pentode RF amp. The suggested replacement is a 1N5GT.
Any idea who made it? My RCA data books cover the era when it must have been
made, but have no listing.

I got the tube info from my old Sylvania tube manual. It was up-to-date
through mid-55. The tube was listed in the condensed section, so it was
obsolete at the time it was printed. Don't know who all made it.

The 1N5GT was fully documented, so it was somewhat modern at the time.

My RCA books have the 1N5GT well documented, as you say, but nothing on the
1SA6. They must not have thought it worth stealing. What do you suppose is
the 6th element in the 1SA6?

There's no "sixth" element - it is a pentode. I have no idea why it's a
"6"...

Try:
1. Antique Electronics Supply in Phoenix, AZ
2. Triode Electronics in Chicago
3. ESRC in Florida


I can't even find a datasheet on the thing... but it looks
like a
pentode designed for a battery-powered radio.... 1.5V
filament, 90V plate.

I am thinking a 1LD5 or 1LC5 might be a reasonable sub,
with a base
adaptor.

There is condensed data in old editions of the _ARRL
Radio Amateur's Handbook_, I found it in the 1947 edition.

Often, the extra element is a shield. So I suppose that could be the
answer.

Many thanks everyone - plenty to go on now!



I have it listed in an old GE Manual if you need any information
on it. Base connections are 6BD, filament 1.4v DC @ 50ma, Ep 90V,
Esg 75V Its an RF Pentode. I found no sub info. Hope this helps.

It's a bit of a puzzle. Pin 1 is marked "S" meaning "metal shell, but that
wouldn't apply to the GT version. Also it wouldn't be considered an
element. If the tube had an internal shield it would be designated IS. No
other elements are shown.
