Radiometer BKF6bc Distortion Meter Audio 1964 repair teardown

Radiometer design from 1964-65 my model is the bc model,
this means i did not find the correct version of manual or schematics,
For Radiometer docs go to peel.dk
A little bit of clean up, caps change, meter glass glue, and it is now almost super nice,
the only last detail to fix will be the 3 high voltage caps.

I use auto generated subs, i am sorry there are a few spelling errors,
maybe one day they can do it better..

In good shape. Nice that it is -almost- working. Always useful to have a distortion meter when doing audio amps.
Thanks for the upload.

Comparing measurement procedure to the hp334a: Did you try to further minimize distortion reading using the balance after adjusting filter frequency?
Your impedance meter setup is excellent. Frequency sweeps and graphical output make the characterization coherent. I could afford a hp4192, but I don't want to make the space for it!
