As Roy, and others, have said: when you need a GR, you need a GR.
Before I bought a 1606, I was once loaned the 900 something predecessor
to the 1606. This instrument is inside of a small, copper lined
suitcase and the particular instrument had been used by the military
since about WW2. The outside showed use. It was spot on with my
standards and, when I opened up the case, the insides were still bright
and shinny. GR made quality instruments.

Hi Mac,

The predecessor to the GR-1606A was the GR-916A, which was the cadillac of
professional bridges prior to the GR-1606A, which came out in 1955. I used the
916A to adjust the tower resistance of WCEN, 1150 kHz, the station I engineered
and built in 1948. The National HRO receiver was used as the detector.
