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" high.

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.
