Loctal-Metal
a metal equivalent of a Loctal tube. These were mainly made during the time
when Sylvania and Philco were attempting to gain acceptance for the Loctal
design at the same time as GE and RCA were promoting the metal design. |
|
| EC81 |
6R4 |
|
M |
Rogers
tube with an Octal Base, and a spray shield - Characteristics otherwise
simalar, for example a 6A7M is an Octal version of a 6A7, with a Conductive
spray coating |
|
| EC84 |
6AJ4 |
|
M-R |
Maintenance
and Repair - Tubes produced for civilian use during the Second World War.
Almost all tube production was restricted to military needs, but some
civilian production was approved strictly to keep civilian sets running. The
MR marking on these tubes was to ensure that they were not used for new radio
production. |
|
| EC86 |
6CM4 |
|
S |
Spray
Shield - often a Rogers or Majestic Brand tube, with a coating on the
envelope to eliminate the need for an external tube shield |
|
| EC88 |
6DL4 |
|
X |
Ceramic
base. Early tube bases made of Bakelite sometimes cased electrical losses in
high frequency, high power or airborne applications. Ceramic has a better
dielectric constant and so ceramic was used for some tubes. This may also be
a Mica Filled Plastic base in some cases |
|
| EC91 |
6AQ4 |
|
Y |
Low
Loss Base. This is often Mica filed bakelite or some other sort of plastic.
Ceramic does not work well for Octal tubes as the keyway can be damaged
easily. The base on a Y tube is often a mottled brown or red in appearance. |
|
| EC92 |
6AB4 |
|
W |
War?
Tubes made to Military Requirements. May be more rugged, higher ratings, have
a low loss base, or other variations. Civilian version may be a numbered
industrial type. For example, a 6AQ5W is also sometimes known outside the
Military as a 6005. Some W types draw slightly more heater power than the
related civilan version |
