For some reason I did not receive notification there was a new response to this thread!
As always you provide a wealth of good information. Thanks!
I do occasionally check the accuracy of the Eico. It's pretty good. I also check on the different ranges, when the value is near either end of the range. I then check the leakage with the Mica Test and applying the internal voltage. In this case it also checked very good.
I liked the comparison in size that you made. So with this and all the other information, I don't think 110pf should be used, but rather 0.0011mf (Sorry, I'm still not into the nf values!)
I know that the schematics do have errors in them, and I guess we don't know for sure, unless we would have information from other sets of this Model to see what values were used in them.
I won't be able to confirm operation yet, as I'm trying to find a replacement 2nd IF transformer.
Good Luck on checking the thousand's of caps you have!
