[R-390] R392 Problem

[Cecil Acuff]

Yeah the 1051 was no fun to tune.  Three of the tuning knobs were tied to several modules through a system of gears and chains.  A beast to work on in several ways...

One of the tuning knobs was right above one of the screws that hold the radio in its cabinet and it usually had a burr on it and would catch your finger while tuning.  I left skin on many of those.  Later radios had little nylon cups over the screws to protect your fingers while tuning...must have been a complaint of many operators during its military service.

Some years ago, I tried lessening the tension on one and learned the hard way that the detent springs are brittle and will snap in two.  Someone on the list (I think it was Roy Acuff) came to the rescue with a replacement, a kind gesture I appreciate to this day.
