princeton speaker help?

[seavote]

hi,
i just repaired a blackface princeton that had been sitting in my brothers closet for about 15 years. cap canister had exploded so i recapped everything and replaced to burned up resistors. most voltages are good and amp is working. the speaker however is not. i get 0 ohms across the speaker terminals. continuity from tip and ground of the 1/4" input jack to the speaker terminals and to where the wires off the terminals enter through the cone. i pushed the cone in to checkthe speaker coil and there was no scratching. i'd like to attempt a repair where do i go next. i wanted to remone the dust cap to see the coil but it appears the cap is glued on these speakers. anyone care to venture a diagnosis?
thanks for any help

First off, you have to have the speaker plug unpluged from the amp to test the speaker for ohmage. The output transformer secondary is very very low resistance of less then a half of an ohm and that's what you'll actually be measuring.
Now, when you say 0 ohms do you actually mean that... in other words, I have $300 ohm meters that still read the resistance of their own test leads so it never says zero ohms unless I "zero/reference" the instrument.
What I am asking, is the meter actually reading a gazillion ohms (or infinity)?
If yes, the voice coil is open... so, don't mess with it because there is nothing special about those speakers, just buy a new speaker for the amp.
The another possibility is, if the meter is actually reading zero ohms, or close to it, one of the tinsel leads under the speaker lugs has broken loose and shorted to the other one.

thanks for the quick reply. i have a cheap radio shack meter. i dont believe it tead infinity but i dont have access to the amp until tommorrow. i'll check then. the speaker is an original from a 1966 amp so i thought it may have some collector value. i see eminence has some replacements for about $75
ps: speaker plug was unplugged when testing for speaker ohms

"is the meter actually reading a gazillion ohms (or infinity)?
If yes, the voice coil is open... "
this a little confusing. if it is reading infinity the voice coil may still be ok??
