manual or Sams will show the break down of values. If
not there WAS a page out there that listed them all.
Do not confuse them with 3 legged caps that Zenith used.
They were blue or brown & had a 22- part number.
Odds are the crystal is the wrong freq. so DONT go tweaking.
Pull one out of a junker must be a 3.58###.

DTMF touchtone phones have always used the same 3.58XXX reference crystal as NTSC color TV's. I think Ma Bell did that for a reason, touch tone phones came of age at the same period color tv's did.
Shango's page has the integrator values listed.
