Connector ID
« on: December 24, 2018, 10:53:34 pm »
I am new to this forum but have looked around quite a bit and it looks like a great place to hang out. 

In this particular post, I am looking for help on ID'ing a connector.  It is an auxiliary power input for a General Radio 1551-C sound level meter.

Dimensions are 1" x 3/4", 6 blade.

I am looking for the male counterpart.

Thanks, looks like a match.   Much easier to find now knowing the name. 

I would like to power the 1551C externally.  It is normally battery operated but, it requires a 67.5 NEDA 200 (Everready 467) battery. 

GenRad made an external supply (1262B) but they do not show up very often.

I wonder what model is that microphone?
It is some vintage Shure model.  The trademark is from the 1930s.

Interesting.  It is labeled as a  GR 1560-P3 as well as having the Shure logo.  The 1560-P5 and P6 microphones were introduced in 1967 and replaced the P3/P4 in applications like this.  GenRad did use different suppliers through the years.  The P3/P4 used Rochelle salts as the element.  The P5/P6 utilizes lead zirconate-titanate for the piezoelectric element.

The second 1551-C (newer, light gray paint) I have has a type 1971-9605 microphone.  This replaced the P5/P6.  It is also a ceramic element.

I have a P6 that pairs with a 1564 Sound and Vibration analyzer.
