[R-390] Line Level VU Meter

[Leigh]

Hello,

I am in the process of refurbishing an R390A.  The carrier 
and line level meters are original and work fine.  However, 
I have a NOS carrier meter (with the correct internal 
resistance) that I would prefer to use and I am looking for 
a replacement line lever VU meter of proper physical and 
electrical characteristics to match this carrier meter.  
If you have such a meter, I would be interested in 
purchasing it out-right or I would trade the 2 original 
meters for it.

I have posted some photographs of the original and 
replacement meters on my Web site.  The carrier meter is 
in very good condition but the glass on the line level VU 
meter is "foggy".  They are both made by Internationl.  
Note that the open viewing area of the NOS carrier meter 
is larger than that on the 2 original meters, but all other
dimensions are the same.

The literature I have looked at references a meter resistance for
the
line level VU meter of around 3360 ohms but mine measures 15.3k
ohms
on a Fluke 77.  The carrier meter measures 18.1 ohms as it
should.  
So let me know if anyone is interested in an exchange or sale of 
a replacement line level meter that matches the NOS carrier meter
that I have.

I guess the other question is if someone knows if these meters
can
be safely opened to clean the glass?  They appear to be sealed.

Thanks to all...
