Yes, I'll let it dry for a day or two. The smoothing caps each have sort of blister (safety valve) with some crusted electrolyte round it. I think I'll have to replace them.

I tested the CRT and the heater is OK and the cathode is emissive. I don't have a proper tester, but at least there is emission. From what I've heard these tubes are usually OK.

Sadly I have just noticed a bit of damage in the phosphor right in the centre of the screen. Its a short (looks black) vertical line about 2-3mm long. Could have been caused by un-suppressed switch off burn, or debris falling of the electron gun during storage/transport in the face down position.

So I'm in the market for a good A59-11W or A59-23W. What do you all think my chances of finding one are? I'll post a request in the "items wanted" here of course.
