Tube Complement: 12BE6 converter, 12BA6 cw osc/if amp, 12AV6 2nd det/af1/avc, 50C5 af out, 35Z5 rectifier. generic descriptions like “two-tube series arrangement…sometimes useful as a power amplifier”4 or “totem-pole amplifier”5. Doesn't pick up any stations. The remaining tube is a 12AX7, probably the most common preamplifier tube in the world. I know the 12FX8 may sub for the ECH42, since it is a 9-pin and designed for 12-volt usage, and is a triode-heptode. Warning: Tubes are not always 100% equal! 50C5 HL94 30A5 HM04. For the valve, I decided on a 6CS6. This is done in case of equal tube type numbers for different tubes. On the left, 12AT7s from the 1950's, made by Mullard in England. The 6AV6 can be wired to run as a single triode (amplifying tube), or as a dual diode tube (diodes are not amplifying tubes - they are used to control the direction of electrical flow). Doesn't pick up any stations. 6 volt transformer (Mouser 41FG010 $6). 00, now $90. The 50C5 is a beam tetrode audio power valve designed to operate in equipment with a series heater chain and no mains transformer. As with the octal tubes, there were 6 volt counterparts to the 12 (for example 6BA6, 6BE6, 6AV6). This list was expanded from a list here (thanks to Jim Cross!). Originally, the 12AX7 / ECC83 vacuum tube was introduced to be a superior option for lower noise and microphonics over the 6SL7 tube that was commonly used in the 1940s. Receiving and amplifying tubes (catalog) U. A few special-quality tubes did not have a standard equivalent, e. 6ak5 tube equivalent. 4SH 16015 4T1 15834 4THA 14756 4-THA 14770 4X140D 14771 4X150A 14772 4X150G 14773 4X450B 14774 4XP 14901 506BU 14902 50BM8. 175 ohms is fine, and will probably be an advantage for higher line voltages. Depending on the tube type, variations of 10 to 20% can be expected to be seen, even for unused tubes,generally the higher the Ik or gm, the wider the variation that one can expect.
