Steve,

I had some extra time last night so I opened up the PCY65S sooner than I
thought I would. I have posted several pictures in the 'inside the dtxpress"
album.

Some noted differences:

1. The narrow leads to the FSR on the top have been shortened.
2. The Rim FSR has just been lowered, I guess to prevent accidental striking
of the rim switch surface compared to the PCY80S with the raised top ridge.
3. The raised rubber surface that makes contact with the rim FSR seems to be
slightly wider than in the PCY80S.
4. The piezo on the PCY80S make full rigid contact with the plastic frame.
The piezo on the PCY65S has a half round 1/32" foam insert between the piezo
and the plastic frame and only half of the piezo is in contact with the
frame!!
5. The PCB on the PCY80S is directly screwed to the plastic frame. On the
PCY65S the PCB has a 1-1/2"x1/2"x1/8" foam cushion that has double sided
tape that attaches it to the main plastic frame and two screws that attaches
it to the outer protective housing on the bottom of the cymbal.


One interesting note: On aTP65 there are spaces and predrilled holes with
preprinted labelling on the PCB for the extra sockets/resistors that are
only present on the TP65S. There are not any extra printing or holes on the
PCB on the TP65S.

When you look at the PCB on the PCY65S, not only does it have the additional
sockets/resistors that are not present on the PCY65, BUT THERE IS ARE
"FUTURE" EXTRA HOLES FOR  A DIFFERENT CONNECTOR!!!!!!! Look at pic 4855.jpg
and you will see a space for a connector CN2 below the connector for the FSR
ribben. Providing  extra holes on what is already a top of the line (PCY65S
compared to a PCY65) cymbals pad doesn't seem logical. The extra holes do
not appear in the "top of the line" TP65S, so what are they
for...........the future three zone cymbal??????? By moving the FSR ribben
down farther on the top it would make more logistical to run a FSR up to the
bell surface for that magical three zone cymbal??
