ampeg 2x12 AV loose jack socket

[Sunnampeg]

hi guys, I start this post because of the following problem: my Ampeg 212AV since new have had very loose jack socket, I've always used other cabs because of this problem, but nowis worsened, I ve to fix it, we are at the point where the jack falls as soon as I play, even at low volume, i ve open it and the jack quality and all the rest around seems very poor material and quality so if I buy and original replacement it is going to be same quality like this one, and my question is, are there any replacement that can fit without modification that is sturdy tuff durable and good quality, in terms of durability and signal quality?
thanks

The plug falls out of the jack, or the jack falls out of the cabinet?

Ok, can you provide a picture? Is the nut missing or is the jack broken?

Nut is there, but it gets loose, the jack socket is internally wobbly when you plug something in

It may have taken an impact before you owned it. Hard to say what exactly how it’s broken.

I believe the entire jack plate assembly is available as a service part.

I just pulled up a picture of that cabinet....if it was the correct picture it looks like the jack has a metal sleeve that is surrounded by
plastic threads. If that is like yours chances are the plastic threads have stripped.
Post a close up picture.

Or it's possible that it's cracked at the base of the bushing. Either way, the jack needs to be replaced, and I'm pretty sure it's PCB mounted.

Here is the part, and yes, it is PCB mounted with a lot of white stuff around the jack, which makes it also difficult to change the jack only

A qualified service tech with access to Ampeg factory parts should have no problem repairing it. The jack has to match and fit 100%, half-baked attempts won’t work.

Next week I will see my tech again, poor him, me, and my pockets also

Hindsight now, but your original post says you've had this problem since getting it new...probably would have been free warranty work if brought up early on. It's a pain to lug a 2x12 around, I know...but at least it could have been free

true in fact. You are right, but it was still working badly, and I've always said tomorrow, next week, and now 6 years have passed. And there is no point in thinking what I could have done .. it's gone

So everything was repaired with my trusty tech, he soldered two brand new jack sockets, they seem very tough and sturdy, very good quality, they hold the jack, with a very good grip.

Have your tech replace the volume pot on your V4B with the correct part as well...

Did not replace the pot I'm asking in advance to avoid problems

Right, I am suggesting that he might be a viable option and he SHOULD be able to determine the correct part without having to resort to guessing or internet folklore (both of which are often wrong)..

in fact, the amp is with me at home. This was research i was doing, hoping to arrive there already with the right part .. but apparently I can not. That's it

It can be a lot more complicated than it looks, especially for older gear. Some parts and mechanical styles have been discontinued, so a pro tech will often need to do some research based on what they know to determine suitable replacements.
