Does anyone know where I can obtain 3 of these tubes?
I have tried the web with no result.
Any help will be greatly appreciated.
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.

I think it might be one of them furrin tubes from before the
standardized letter/number numbering system.

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.
