Hi,
Has anybody asked you what you used to make your measurements? Modern
meters - DMMs - present almost no load at all to the circuit under test.
The readings listed in manuals for old gear were probably obtained with
old style V-O-Ms. Resistance readings shouldn't vary much but voltage
readings in energized gear certainly will. Add that difference to the
normal variations of tubes, caps and resistors with all of the
accumulated tolerances.
Good luck with your project. You can always learn from projects like
this andafter al the work you will have a working radio:)
73,
Bill KU8H
