what are the most commonly used tubes in vintage radios
I'm writing a program for my intro to embeded systems class, to replace the instruction manual for my B&K Dyna Jet 606 tube tester. I need to have it finished by wednesday and don't have time to coppy all of the tubes in the settings part of the manual. I'm Intend to include AA5 tubes as I know they were the most common however the only AA5 radios in my collection that I have access to are the octal type, and I can't remember the numbers for the types. I'm going to try to include the apporximately 50 most common types from radio, TV, and HiFi. The oldest types the Dyna Jet tests are octals and loctals, so I can't use anything that pre dates them. See my similar posts in other parts of this forum.
Thanks, Tom C. |

In most "normal" Europanen radios manufactured from the mid '50's to the '60's I've seen:
- For audio: EL 84 (6BQ5) (6Π14Π/6P14P) - for more powerfoul speakers (some use the EL 84) and EL 95, ECL 82, ECL 86 for less powrefoul speakers; ECC 83 was a preamplification tube. - For radiofrequency: EABC 80, EBF 89, ECH 81, EF 80, EF 89, ECL 85 (for F.M. tuning) There are some with more exotic tubes and I do hate the exotic tubes, like the bloody ELL 80 (sometimes you have a socket for 2 x EL 95)or that disaster called ECLL 800 (this it was used in the '60's at some West-German radios for minituarization). The rimlock series tube are hard to find in Europe. Sometimes is easyer to find tubes from the '40 and '50's. |
