TV7 Tube Data

[Dan Bal]

Hi. I just bought a TV7 A/U from a guy on ebay who, now that the sale has completed, will no longer respond to my emails.
The data book included has almost every tube that I need to test so far except one. I have a World Audio Design HD83 headphone amp. It takes ECL83 tubes. I can not find it in the data book. Where would I look to find test data that is not in the book?

This is a direct pdf download for European tubes, but doesn't include the ecl83 so hopefully someone can help you.

This is a great resource Shawnnn, Thank You. The ECL80, ECL82, and ECL84 are all included. So strange there is no ECL83.

I appears to be quite a unique tube and I don't remember ever seeing on before. Listed for audio service, it is somewhat similar to the 6GH8 or 6U8 etc. It also doesn't seem to have a "drop in" replacement. The best bet is to study the https://frank.pocnet.net/sheets/129/e/ECL83.pdf data and see if you can come up with a setting.

Looking at the datasheet it is similar to ECL80 albeit with different cathode connections. However, the pentode section is more akin to EL95. Triode is ECC83-ish.
