Cetron 811A/JAN
(TUT) 811A-JAN
Never before at this price, 811A/JAN Cetron. Buy these late date Cetron tubes made to the original RCA specifications because Cetron (US company!) bought RCA. Anyway, they are made to run horizontal or vertically. YES, you are correct!

This is the exact tube Collins installed in the thousands of 30L-1s they produced for 30 years! Enjoy higher duty cycle and will last many times longer than imported tubes.

Solid State Replacements
5U4 / 5R4, 5Y3, 5V4, 5Z4

(SDI) 1N1239
Plug in solid state replacement for vacuum tubes 5R4 & 5U4. Octal base. Rated @ 2800 vdc, 1 amp. 1-3/8" diameter x 1-1/8"H.

Solid State direct replacement modules are much more efficient than their vacuum tube predecessors. In some case, dropping resistors should be used if the higher output voltages often yielded with these diodes will create an unsafe condition. No heater current is required, saving watts there too.
