Nice catch! Did you get any sort of documentation with it?
I have a bunch of those counters but only one amplifier, like the in the second auction, and a bunch of different probes plus a bunch of different shields/holders for the probe above the sample being tested, made from aluminum and lead mostly. The most common failures have been the 6BG6A tubes being poor after long usage and a few transistors that have been blown. The plastic window in front of the mechanical counter tends to come loose and drop inside the case and that means that dust enters the mechanical counter which makes it count poorly. Apart from that all of mine are working flawlessly. /Martin On Wednesday, 19 April 2023 at 19:02:04 UTC+2 Mac Doktor wrote: > I just received this: > > https://www.ebay.com/itm/234956144440 > > > Appears to be working.
