Damned if I know what a 25 pin DIN plug looks like, but a DB-25 looks like this:  http://image.made-in-china.com/2f0j00oMUEHKnRhykt/DIDC-25pin-Male-Connector.jpg  DIN plugs are round.

There are pin extraction tools that look like this:  http://www.allwaytech.com/catalog/images/large/28-7013-HT-101.jpg

If you don't need surgical precision, a pair of needlenose pliers will allow you to snap off a male pin. Just be sure you snap the correct pin...

If you need to remove it (as in the socket is keyed for NO pin at that pin location), you can use the removal tool PROVIDING the DB-25 isn't potted and non-accessible. If you just need to disable that pin, you can just cut the wire to that pin on the cable and leave the pin in place in case you need to re-use it.

Curious but what kind of amplifier hookup uses a DB-25? While I may not have had hands and eyes on every amp ever built, I have seen alot of them and none required a DB-25. Most only require a phon jack for keying, a coax in and out and perhaps a molex or DB-9 to radio for control lines. If you're using a DB-9, don't be mistaken thinking it is a serial port and try to hook it up that way. If it's a DB-9, it could just be a simialr 9 pin as used ina serial but wired totally different. Be careful.

Yes, the industry standards are readily available for those that read for their continuing education.

D-Subminature connectors -- used on computers since late 1960s and 1970s.

Never cared for the "pull pin" with a pliers Neanderthal method.
The extraction tool is sold at many Radio Shack stores (parts drawers) and
virtually every personal computer store on the planet,
so access to proper (and cheap) tool is no excuse.
