Repetition: The archives are useful sometimes, but I am not so sure this time. Although I have never seen one I would be interested in a wiring diagram of a Kafoh speed tester. All I know about them is this:
https://kyp.hauslendale.com/classics/forum/messages/6899/6005.html
Can anybody with more knowledge please help?
There are Kahfo shutter testers with different tubes sets (this one probably built around 1960: ECC82, ECC85, EF80, 85A2, name of photomultiplier not known, probably 931A). Wiring diagram wanted/ needed. If anyone reading this has more info, please help, W. |

... well, ok, so I am alone with this problem. Meanwhile I have got the tester back to working condition after replacing a 0.05Mfd condenser which turned out to be shut, but in order to get down to the nitty-gritty I need the wiring diagram. I do have a manual, but it does not say anything about the internals, an overhaul without a schematic outline would be tough. |

Thank you for the tip, John, in my younger years I was hooked on vintage tube radios and stuff, and just for the fun of it I restored tube-operated darkroom equipment (auto exposure cassette for photographic paper, "Howaldt B 18". 150C2, E92CC, P569.1GR.V/VI). Every now and that old feeling for tube gadgets comes back and faces me with new problems.
While poking around for the wiring diagram I was offered access to a forum in this country http://www.jogis-roehrenbude.de/ but decided not to get registered because I know what being addicted to that sort of activity may lead to ...
(trouble&strife, more things in her way, etc.).
I'll have to ponder it over, thanks again for your encouragement, maybe in return you find the above link useful, W. |

Thanks, Wernerjb. Interesting stuff. And it will help me bring my "A-Level" Deutsch up to scratch! |
