[Boatanchors] DX-100 Voltage and resistance chart !

[Jim Wilhite]

They didn't supply much but here are some resistance measurements.  All are 
to ground.

Low Voltage Supply        Low voltage Filter       32K
High Voltage Supply        High Voltage Filter     30K ohms
Bias Supply    Pin 2 or 7 of 6AL5    5.6K ohms
Final Grid Circuit    6146 Grid Buss    6.7K ohms
Oscillator Screen     Pin 8 of 12BY7    60K ohms
Modulator Screen     Pin 3 of 1625    15K ohms
Final Amplifier Screen    Pin3 of 6146 tubes    52K ohms

Be sure that low voltage supply filter cap is good.  That is a cap input 
circuit and the first section gets a lot of abuse.  I have always found them 
leaky which causes all sorts of grief.

Happy New Year Anchorits , My DX-100 suffered a catastrophic failure after 
attempting to tune into a no load (coax switch in  wrong position) arcs, 
sparks, smoke et. was the result. Does anyone have volt/res. tube chart that 
has been developed as Heathkit did not provide one. Tnx 73 Bill KE7KK
