Fender London Reverb

[karl]

I was stacking my London Reverb on top of my 67 twin reverb 2 and it fell off busting the input jack. Naturally, it's made of plastic. Any idea where I can purchase another?
Thanks/Karl

Looking at gut shots of the Twin Reverb II the jacks look to have metal sleeves and nuts. Since they're PC mount type I'll assume the body is plastic. I don't know if you can still get that exact part to fit that board. An extensive search at Mouser might reveal something. Measure the jack PC pin locations relative to it's length and just look at all the PC mount pots you can. You will also want to be extra certain that the PC pads aren't damaged. A retrofit is always a possibility too. Sorry for you. It looks like you'll need to remove a whole bunch of stuff to get to that jack.

Unless you mean to say that the London Reverb jack is busted? In which case I have no idea what jack it could be. I'm not familiar with the London Reverb and I don't know how it's contructed.

Antique stocks the current style jacks, the London Reverb I think is from the '80s and may have the older style plastic jacks that are much harder to find. There are a couple of work arounds that can get the amp fixed.

If you post a photo of the jack we can help direct you in the right direction.

Looking at the layout, it looks like the old Switchcraft right angle series.

Look down to jacks of type F on the page, specifically the RN113BPC. That has a ring contact we don't need, but snip it off. Ideally I;d look for an RN112APC. Mouser doesn't list it on the page, but voila... they do seem to sell it:

In my twisted head, I think of those as "tombstone" jacks, because the little gray plastic cover is shaped like one. The cover snaps out for access to the innards, and should have the part number stamped on it.


Might that be what you have?

Enzo, you may be right, but I don't remember Fender using Switchcraft jacks on those amps. The ones that I remember are the low profile jacks like some of the ones that Marshall used in those small practice amps.

The mounting hole is very low to the board surface, so it's had to find a jack that will fit in there. A photo of the jack would help.

I'm looking at the board layout drawing. It has the right pc trace footprint, and the same tombstone outline.

Check it out.

Right again. The pc image helps a lot.

The correct input jack is the four pin. There are also 9 pins on the board.
Substituting is pretty silly since you can buy the exact one from several places.

HOWEVER, it takes a fair amount of skill to remove and replace the jack.
I have seen DIY destroy the tracks on the circuit board many times.
You need a soldering station, not a POS radio shack soldering iron.

So if you don't have the chops and the tools, get somebody to help you.

On these amps I replace ALL the jacks when the circuit board is removed.
The jacks contain switching contacts that fail from corrosion.
It makes plenty of sense to replace them all, when the board is removed.
Also when the board is removed, clean all the controls with Deoxit D-100 and Caig Fader Lube.
It's much easier to clean them when the board is removed.

When you reassemble, make sure to coat the heatsink and chassis mating surface with plenty of zinc compound, then tighten the bolts.

Those jacks you mentioned are wrong. The London reverb was an early 1980's amp. The 4 and 9 pin jacks you linked were not used by Fender til 1988. The London uses 4 different types of 1/4 inch jacks. The part number for the input jack is 018594, nothing like the 099-0912-000.
Enzo is correct, as usual. RN112APC Switchcraft.

RN112APC Switchcraft.

Available at Mouser... Who suggeted that in the first place??? (placing hand in air, like I don't care and saying "whoop whoop")

It does happen, often, that a manufacturer has a special part made for an amp line. Way more common now than then though. And even now it's usually possible to find an equivalent part in the standard stuff.

Outstanding!!! This place [and members] always come through!

Now, do you still have that layout PDF? I can't open the link [it may be too old like this thread]
