Hi, while listening and staring at the front of the 390a, I noticed that
the two meters on the front panel have somewhat different shape/size. The
first noticeable difference was that the line level meter window extended
further down and revealed the pivot point of the meter whereas the carrier
level meter on the right had a smaller window. I looked over at the 390 and
noted that both meters on it were similar in shape to the 390a carrier level
meter with the smaller window. The scales, etc seem to indicate these all
are original meters. The 390 meters are different in one other aspect.
They seem to have stamped metal housing with a sloped front transition
immediately below the window whereas the 390a meters are blockier with more
of a corner below the window.
Some measurements indicated that the 390a line level meter with the larger
window was 1.8 inches outside, which was the same outside size as the two
390 meters. The 390a carrier level meter was larger, slightly under 1.9
inches. Is this variation in meters typical of variations over the
production life of the 390a, and have others seen this variation on their
radios? Dan.
