Ken That is one of the things a previous owner had done probably in 60s or 70s . He probably added the 2 Si diodes then. The genuine pots are very small and the one that should be there is missing replaced with that one , presumably the smallest he could find but too large to fit in place. He must have given up when the carrying strap broke and CRT cracked. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

Ken Error. The original is still in place but has a broken tag, but enough remains to measure resistance. The Al cased one is wired in , instead but is too big to replace the original. |
