Hickok 600A tube tester
#14

Ok,, My 2nd goof.. Meter is Good.. I didn't disconnect the leads from it. After I did meter was OK.

But still will not read when P7 is pushed for the line adjust..

I tried to check backwards .. Checked the Switch, Pots in line Cleaned all pots .. I did notice that the Bias Fuse they call it should be a # 49 Lamp.. Mine has a #44 lamp in it..

The 49 lamp is a 2 volt .06A the #44 is a 6.3 Volt .25A The # 44 lamp is Good..

Would that cause the meter not to Read?? I would not think so... but cannot find anything else that would cause it not to read... Maybe I am missing something??

Only other thing I found was this..

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




Anyone have a layout of inside of this showing part layout??
