Reservoirs don't have stiffeners...
Regarding the conical compression spring, if memory serves, it's in the bellow that
also contains the accent (or crash) bellow. It's purpose, therefore, is to prevent the
bellow from closing too far. You might also notice that the tension of the 'V' springs
is different in the two reservoir bellows. According to the Standard service manual,
there are 7 lb. and 8 lb. springs. The heavier springs go in the bellow without the
While there are no explanations in any book or manual concerning any of the
springs in the reservoir bellows, logic dictates that there should be somewhat of
a balance in terms of the vacuum level required to collapse the bellows. So, as
the bellow with the lighter springs reaches full compression, the moveable board
runs into the conical spring.
Regarding the accent (or crash) bellow, it only reacts to sudden changes in the
vacuum level. That's why the spring that holds it open is very light weight. As long
as the vacuum level remains fairly constant, regardless of how low or high that level
is, the crash bellow (which is actually a valve) doesn't react.
Regarding the felt under and in front of the conical spring, it's only purpose is to
prevent noise. I would not suggest removing the conical spring unless it is loose.
As I recall, it's held in place with horseshoe nails, and any looseness will cause
rattling inside the bellow -which would be annoying. As for the felt that the spring
runs into when the bellow collapses, in the past I have replaced that with a piece of
thick flap valve leather. Here again, it's only function is to prevent tapping when
the spring makes contact with the moveable board.
Lastly, while I'm certain that I took pictures of the parts inside the reservoir bellow
in my early years, all of them were lost when one of my hard drives crashed about
ten years ago. So, I'd appreciate numerous pictures of the location and placement
of the various parts from different angles. Eventually, I'll create another webpage
about the springs and crash valve.

Since "Player-Care" is an internet business, I prefer that we correspond via E-Mail (click here to fill out the 'Request Form'). However, if I'm not in the middle of some other activity, you can reach me at 732-840-8787. But please understand that during the hours from 8AM-5PM EST (Mon-Sat), I'm generally quite busy. So, I probably won't answer the phone. If you get the answering machine, please leave a detailed message stating the reason for your call. Also, repeat your name and phone number clearly and distinctly. By necessity, I prioritize everything in my life. And, if you call and just leave your name and number, and ask me to call you back, it might be a day or two before I return your call. Why? Because I don't know why you want me to call and I might not be prepared to assist you in an effective and efficient manner. If you leave me an E-Mail address (which I prefer), spell it out phonetically. The more you do to help me, the more I can help you in return. Don't rush. You have four minutes to record your message.
