Thanks for all the replies. The one in this link https://www.surplussales.com/Variables/Ceramic/CerCap3.html posted by Gary looks amazingly close. I'm going to see what else they have and make an

No issues to be expected at the frequencies involved. Any good-quality trimmer should do but you may prefer the looks and fit of an original...... As promised, I'll have a look on Tuesday but please,

I recently bought one of these assortments to get several different values for a project. I haven't used any of them, so

I was partly wrong. Tek retooled the front panel for BNC, but not until 1967. From 1963 through 1966, they used the UHF front panel with a square-flange BNC jack and plastic trim covering the

My 535A and G are Guernsey-built. The 535A is s/n 101936, and the G is s/n 101127. They both have BNCs which look like they were factory-fitted, though they are of the special Tek type with enlarged

Just realized yours is a 468. It's probably the same as the equivalent cap in a 465(B). I'll be in the lab coming Tuesday and have a look, possibly take a few pictures. I can't imagine the

According to the later manual Type G switched from UHF (131-012) to BNC (131-277) at S/N 9480. No idea in which year that was. Albert

Nick, I have a 2246A that I had to overhaul, which most likely has the identical power supply for your 2247A. I would do a search for the 2246A power supply also here. So I will refer to the

I run into the same problem many times when restoring radios. The original trimmers are simply not available So, I order new modern SMD trimmers from Mouser, and simply solder legs onto them. Works

I added a photo of the capacitor. Just in case. /g/TekScopes/photo/76822/0?p=Name,,,20,1,0,0

It is not critical.

Hi Nick, can't really give you other troubleshooting tips for a dead 2247A power supply, as I fortunately never had this problem with my own scope, but I hope in the end its something easy to fix.
