This small sampling seems to imply the early Pioneers did have the metal plate, while late model Pioneers did not have the metal plate.

As noted above, this is likely not related to the problem, but it does contribute one more useless little factoid about the differences within the Pioneer family.

Later in manufacturing or in design?

My units:

17BII - 1996 - has metal plate
20S - 1991 - doesn't have plate
21S - 1991 - doesn't have plate
22S - 1990 - has metal plate
27S - 1988 - has metal plate
32SII -1993 - doesn't have plate

In the begining I thought it was used only in the "high end" hardware (dot matrix, buzzer) but finding it in the 22S and not in the 32SII throws this...

So it is possible that, as you say, it was used in first units designed and removed later, but 20S and 21S are quite early models...

Actually the 20S and 21S are relatively late Pioneer models, arriving in Jan '89 with the 10B; only the 17BII and 32SII came later.

The 17BII seems to break the idea that later models dropped the metal bar; I just checked 2 17BIIs, a brown and a black version; both have the bar. Could be ralted to IR, but the 22S had no IR. Hmmm...
