All, I have a model 600A Tube tester from the estate that I was looking at. I haven't bought it yet. But was allowed to take it and look it over..

Looks good from outside.. But as I was checking some parts on inside I ran into something..

5 Resistors on a board.. Does any one know what values these are? Hard to follow schematic as it not clear..

This is what I get .. From left to right

Bottom to tap 958 Ohms Bottom to top 6644 Ohms

bottom to middle 25.5 Ohms bottom to top .58 Ohms Top to middle 25.6 Ohms..

That one makes no since at all I checked it 5 Times..

Next Bottom to top 1831 Ohms ( its marked 1800 Ohms)
1296 Ohms Should be 1200 Ohms..

Last 155.9 Ohms and .3MH

There is corrosion all over under chassis .. A fine white powder

Anyone restored this model??
