On
the left there is Telefunken RS 384 used in
Wehrmacht radios since 1939. On the right there is Soviet tube GU-80
known since 1955, apparently an exact replica of RS 384
including same base design.
In
between the RS 384 and GU-80, there is Telefunken RS 383
at the back wall. No Soviet analogue of that tube was
known.
To
the left of RS 384 there are three tiny Telefunken tubes on
display - SA 1 and SA 100
VHF diodes and SD 1A triode which could
be used up to 60 MHz.
Further
right there are pretty rare Wehrmacht tubes displayed - LG 76 gas filled
tube (Nullode) featuring two copper disks which
was used at the input terminals of radar receivers, RD 2 Md2 magnetron
delivering 0.5 W at 2 GHz and another magnetron,
RD 4 Ma delivering 14 W in
1,150...1,700 MHz band.
