Tube 50C5 or Röhre 50C5 ID1071, Beam Power Tube, Miniatur-7-Pin-Base B7G, USA 1940 and Power/Output shown. Radio tubes are valves.

The 50C5 is a beam tetrode audio power valve designed to operate in equipment with a series heater chain and no mains transformer. It is an American design and consequently the typical voltages employed are 110 Volts. With an anode load of 2,500Ω the 50C5 will generate 1.9 Watts at 9% total harmonic distortion.

2022年11月21日 · I recently picked up a 60’s Panasonic “Matsushita” RE-784 tube radio that uses a 50C5 output tube. The radio worked, but the sound was distorted when it was…

2020年5月26日 · The 50C5 is electrically identical to the 50B5, but the insurance underwriters of the day instituted "creepage rules" for the new PC board based radios requiring a change of pinout. The 50C5 was first seen in 1948. The 6 volt version is the 6CU5 which appeared in 1956. The 6EH5 has the new pinout, so it came after the 50C5.

2024年9月7日 · The 50C5 is derived from the 6W6 and has the same characteristics except for the heater and plate dissipation ratings. Both have a 7.5 watt heater that has far greater emission than the 6AQ5. The 6AQ5 is based on the 6V6GT.

The transmitter consists of a 50C5 crystal oscillator, which operates on either 40 or 80 meters. Since the 50C5 has a 50-V filament, it uses a 400 ohm 20 watt dropping resistor instead of a filament transformer. The power supply for the plate and screen voltages is a doubler which provides about 350 VDC.

2015年6月25日 · 50C5 is a audio output Beam Pentode good for 1.9W output. Looks like you have the remnants of a radio. You can't arbitrarily substitute tubes. You need to look up the tube datasheets and understand what they were designed for and their pin-outs before swapping them.

Name: 50C5 Use: Miniature tube type used in output stage of compact ac/dc radio receivers. Notes: Requires a miniature 7-pin socket.

The 50C5 is an American audio output beam tetrode. It was designed for operation with anode voltages of 110 Volts and would be found in broadcast radio receivers with series heater chains. Rather than dropper resistors in the cabinet the USA market tended to use 'line cord'.
