Welcome to the forums!

You should be able to get a new repair tip/end. If you post a picture maybe we can help you find one.

Part 1. Getting the remains of the tip out of the Input #1 jack. Suggest at first getting a screw with a thin tip (perhaps a drywall screw) and seeing if that will catch in the broken end allowing you to pull it out. If that fails you may have to disassemble the amp so you can poke a thin screwdriver in from the internals side and push the broken piece out.

Part 2. Putting a new plug on the cord. I think Radio Shack still sells replacement plugs Do you have similar cords (or check the other end of the damaged cord) to see whether the plug is three conductor (extreme end (called the tip) with a small section (called the ring) immediately behind it and then the main part of the shank (called the sleeve) versus two conductor (just one separate small section at the extreme end and then the main part of the shank. If enough of the plug remains attached to the cord, you need to figure out which conductor goes to the tip and which conductor goes to the ring for a 3 conductor plug, before you tear the remains off of the cord. The jacket of fine wires goes to the "sleeve" terminal which is usually a strip of metal. You will need to do soldering. You need to be careful so the plastic core of the cable does not melt while you are attaching the wires to the plug. (Or if the cord is not too long, buy a new one and throw out the old one.)

Thanks - I tried the screw method, but couldn't make it work. Will I have to take the amp completely apart to get to the input? (that's how it looks to me).

Take the amp apart and push the tip in. If it won't push in...... you can push it out with a small screwdriver.

Thanks. That's what I was afraid I'd hear...

Not too hard. I think there are four screws that hold that black piece of wood in place on the back and four screws that go down from the top into the control plate.

You should be able to push the remains of the plug through the back of the jack with a thin long screwdriver. unplug the power first of course. the plug remains should fall to the bottom of the amp floor as the floor of the electronis base is mounted upside down on the old twin as I recall. (Used to lug one around to shows back in the eighties...).

On second thought, based on the looks of The jack pictured above, you might leave the amp sitting upright and push the broken off piece further in and that piece would drop free ... but ...

Use moderate force only for an additional quarter of an inch. Then very gently continue to push the piece, stopping if the piece seems to be stuck.

1. Your jack might be shaped differently, with a J or U shaped piece in back where the broken piece might catch on and deform,

2. There might be other possibly fragile parts close behind so the piece does go all the way in.

If the piece does drop free inside, don't forget to remove it before turning the amp on again.

Needle nose pliers can usually grab the shaft of the center pin enough to pull it out. If not, as PJ said, you'll have to take out the chassis. After you remove the four long screws from the top (held on with nuts below the chassis) the chassis should slide out toward the back. You may have to remove the connectors to the reverb pan and the speakers. Take a photo so you can put them back in the right jacks.

This video shows the proper way to discharge the caps. If you're not comfortable doing this, take the amp to a pro. Why?

THERE ARE LETHAL VOLTAGES INSIDE!!!!! The capacitors can hold lethal charges for days. Talking hundreds of volts and enough current to kill.

Even after you think you've discharged all the caps, treat the amp as if it you didn't. Wear safety glasses. If you've ever seen a capacitor blow up you'll know why, and all it takes is a quick touch to short it to ground. Put one hand in your pocket while you're poking around inside the chassis. Use the wooden handle of a small artist's paint brush to persuade the broken piece to exit the amp.
