[Nuvistor]

The voltages are not that far out, I have not taken note of the voltages across the resistors and capacitors only the ones from the manual.
Check C6 and C7, those being faulty can cause damage, the other slight differences in the voltages will be small changes in the value of some resistors and degraded emission in the valves but they are not that bad.

Has John asked do the amplifiers work and if so how well?

If C6 and C7 are good and the amplifier works well I would leave it as it is.

See what other opinions are.
