I'm just not electronics savvy enough to do it. So I'm reaching out to forum members to help me with this. I have the chips from Mouser and I will happily compensate for the time and effort needed to install the chips in the amplifier.
Thanks in advance to anyone who can help me out with this.

Joe-
If your 112 is the older version with the snapped-in chips, it's not difficult to do the swap yourself. I have almost zero electronic expertise and I did it on my 112, but that was at least a decade ago, so I don't have the instructions anymore. I'm sure, though, that someone here knows what chip goes where. You might have to pull your 112's chassis to see whether the factory chips are soldered or snapped, but it's fairly light and comes out easily.  |

Just to be clear for my edumacation: What is involved in doing the Fox mod?
Replacing only chips/ICs?
Any capacitors, resistors, etc?
Anything else?
Also for the OP: If you can briefly pull the chassis out to see the circuit board, and snap a photo, that would help.
Even with minimal electronic skills, there is a possibility that you may be able to do this yourself. |

Hi Dave and ajm--
My 112 is the older version with the snapped-in chips. I can identify which chips need replacing.
The problem is (at least with the new chips) is the contacts are splayed too wide to go into the sockets. They require what is known as "spanking" to get the contacts on the chip(s) to align properly with the socket(s). This is where you hold the chip in both hands and press it against a hard surface to get the contacts to align correctly. It is during this step where
the contacts get bent (at least when I do it) and I must be using too much pressure or something because I'm not getting the desired result.
Hence, my original request that someone who knows what they're doing perform the mod.

Both. The Fox "intense mod" was a major upgrade. You sent your chassis to Ken. He upgraded the op-amps and several other components, including filter caps. You would get a little baggie back with the parts he removed.
After he stopped doing the intense mod [on the NV400) , he sold kits that were just the chips. The chips can be purchased from several online electronic parts stores.
I don't remember if he performed intense mods on the 112 or just sold chip kits.
