Re: Grundig TK 819 Any Useful Info
After some chasing my tail, found R40 and associated R19 were physically on the other side of the chassis, nowhere near the ECC 81 valve. Found missing anode 2 voltage on the ECC 81 was due to broken wire at the valve pin (this wire connects back to R19).
Wire probably got broken yesterday during very awkward capacitor replacements at the ECC 81.
Even though I have tried to thoroughly clean the snubber leakage sticky tar like material from the ECC 81 valve base socket pins, found that each time valve is removed that the valve pins come out coated with tar, so have been replacing/removing the valve several times, each time cleaning the valve pins, slowly it is improving.
Plan to drill hole in rear of chassis to fit a double pole on/off toggle mains switch and wire accordingly.
Will go quiet for a few days as going to visit family.
