Bypassing Bugera broken input jack?

[joshual]

Hi there,

I own a bugera 333 and the input jack broke some times ago. Now it's all dead.

I wanted to know if it was possible to bypass the input jack (that is on soldered the pcb)?

There is a connector with two little cable next to it that goes to the other main pcb. But can't find any info if it's actually wired to the input jack.

This way i could just bypass the broken input jack and solder a normal input jack.

I joined photos of the cable.

Thanks a lot for the help!

Why not just replace the input jack?

And your ohm meter will tell you if the little cable connector is wired to the jack.

But I agree, I'd just replace the bad jack. For this amp that IS the a normal jack.

Is it the jack or the solder joints to the jack? The repetitive force of plugging/unplugging can wear at the solder joints.

The repetitive force of plugging/unplugging can wear at the solder joints.

In my experience (not with this unit, but with "stuff" in general) the repetitive force of plugging/unplugging can also crack the PCB at the jack's land. If you don't care about looks, sometimes installing a panel mounted jack with a cable to the PCB can be easier and more reliable than patching the PCB. You would need to, um, trace the traces from the jack pads to find a suitable place to land the cable. (Not to be a pusshead, but I can't even see the traces in the poorly-lit photos you attached.)

Because this kind of input jack is hard to find and made of plastic. i am a touring musician and don't want to have that kind of problems any more. :-)

It is plastic to isolate the jack from the chassis as part of the overall grounding scheme. By switching to a metal bushing, in some causes that causes hum.

I replace those with common Switchcraft jacks of the same sort. Seems to me I have to burr out the panel hole just a hair, as the original is ever so lightly narrower.
