It¡¯s very unusual.? A lot of these are wack-a-doodle.? Bizarre readings, all over the road.? A few, however, are just fine.? Never seen this many bad ones in any one radio.

Wow, that is interesting.? I am going through an SX-100 and it did not even cross my mind to check the old micas.? Typically once they are placed under voltage for some time, their ever so slightly skewed value does not shift around. To replace any out of tolerance ones with new ones may mean let the new ones cook under voltage for some amount of time before aligning the radio.
Seeing something in the restoring of the S-40 here that I don¡¯t see very often ¨C some VERY significantly drifted micas.? Found a few that were crazy out of spec.? I¡¯m replacing them with modern silver micas where needed, but I¡¯m curious if Hallicrafters is known for some wacky micas.?
