[Milsurplus] Japanese 94-5 Corrosion (Hubert Miller)

[robinson at tuberadio.com]

Hi Hue,

The valve bases are European 4 pin base
same as English 4 pin.
I took some dead UK tubes
removed the base,
fitted an octal socket to it,
and wired them for the appropriate valves.
The Japanese valves are GT envelope
so the USA G envelope tubes
still fit in the same space/height.

The radio I am working on is a 94-3C
but the valves are the same height.
Some Japanese valves have other bases of course.

I will take some pics and send them to you.

Regards
Ray
