Philco 50 (Nathan's)
#10

Speaking of resistors, last night I went through and checked them against measured values:

No.   Expected    Actual        Verdict
9     32K         103K          bad!
11    10K         11.2K         good
13    240K        346K          bad
14    490K        593K          a bit off
20    490K        (infinity)    really bad!
21    160K        214K          bad
23    15K         16.1K         good
26    25K         23.5K         good
29    99K         140K          bad
27    99K         148K          bad

So most are pretty far out of tolerance.
Time to break out the repro resistor production line!
