Is your original MR2 still present in the radio? If so does it have 5 connections?
I have reconnected the original MR2 in the Honey coloured R66 and it seems to be working just as good as the pair of 1N4007 I had replace it with. I have left MR1 in place but have replaced it electrically with 1N4007. The three LT smoothing are also in place. I have done some testing and managed to get 2 to give satisfactory performance with only one now being electrically replaced.
Does anyone have a solution for removing a sawn off pot shaft embedded in the volume knob which also has the grub screw stuck as well!
