Who Rebuilds Triplett 630 Type 4

[lego4040]

I was given an old Triplett 630 type 4 and It needs service. I found two blown resistor but the rest tested ok. Outside it is in great condition and It would be a great addition to my bench along side of my other equipment. I also would need probes since the ones that were with it aren't even correct for it . Anyone have a service place recommendation? I am on the east coast
