Thanks,

yes those are carbon resistors, and I ordered everything from Mouser yesterday. All 5 of them.
Plus, what bugs me (I am sure it does not matter) - the mica cap bypassing the detector's (24) anode, which is supposed to be 250pF, when disconnected and measured, was 400pF.

I thought mica caps were long-term stable. I am sure this does not matter much in this case, but ordered another mica cap for the 250pF just in case.

I want to have all resistors right, so to compare the DC voltage values with the chart first, otherwise it becomes a guessing game. My non-tube troubleshooting experience tells me "get all values right, then troubleshoot". Usually makes all that much easier.

The last thing I will check is those potted caps and the two caps in metal boxes (so far I measured two of the potted caps I could easily unsolder, and their values were right where they are supposed to be). Hopefully the rest is like this also.
