I have a mirror imaged pair but the serial number is not visible.? Where would it be placed?

I can add that my original pair (which I bought while in high school) were not mirror imaged?because i remember the instructions they mailed out to do it yourself. This was in winter of 1975. They had the yellow Mexico caps .

This is what I recall about the early DQ-10's...

The first that I knew about were not mirrored and did not have the Mylar capacitors (the bright yellow ones).? The first I ever saw had the Advent woofers.? I do not recall ever seeing non-Advent woofers except where someone intentionally swapped them out (for whatever reason).
After that they upgraded to the Mylar caps but were still not mirrored.? This went on for about 3 or 4 years.
Finally you could get them from the factory mirror imaged.
Mine are numbers 24091 and 24093, originally purchased in late 1977 or very early 1978.? At this time they had recently switched over to the Mylar capacitors but were not mirror imaged.

I hope that helps.

I was thinking in an earlier mail of what is now in

Look in the DQ-10 section, perhaps match the rev info to what selected components your DQ-10s have
