There is a voltage chart for the Heath DX-100, that was supplied, to me, from Heath in 1961.  This was basically an "in house" document and was not widely distributed.
I grew up about 35-miles from the Heath plant in St. Joseph, Michigan.  The mailing address was Benton Harbor but the actual plant was on Hilltop Road in St. Joseph.  After getting my driver's license, I would occasionally drive up to St. Joseph to "drool over" the kits.  There was a show / sales room, just to the left after entering the front door, where one could look at and even purchase kits.  If one had a question about any Heath item, the showroom representative would call back into the actual plant and, in a few moments, someone would come out and answer the question.  This person was often the lead engineer on the product.
Often, the engineer would make some suggestions on modifying the equipment and draw a schematic on a piece of paper.  Then, the engineer would go back into the plant and return, a few minutes later, with a paper bag with all the parts needed to make the modification(s).  No charge for the parts! Glen, K9STH

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.
