Another thing you need to know...the voltages given in the original circuit were made using equipment o the time...meters typically were 1000 ohms to 20,000 ohms per volt...it will usually say which meter was used. Unless you have a similar vintage meter it is likely you will be using a much more modern digital meter which has a much higher impedance (or internal resistance if you prefer). Therefore expect voltages to be different, sometimes by significant amount. This doesn't indicate a fault, it simply means the meter presents a much lower load on the circuit making some voltages read significantly higher.

Back in 'the day' using meters of the time, we expected voltages to be around 10% - 15% within published figures...experience also told us if there was anything really wrong. Digital meters will tend to read higher voltages in high impedance circuits....the anode voltage of the UABC80 for example may be quoted on the circuit as 80V but your digital meter may indicate 120V. No it's not a fault, your meter is just loading the circuit less and reading a higher voltage. However measure the main HT rail which is a much lower impedance and you'll probably find it measures close to the published voltage (assuming the rectifier is up to scratch).

If in doubt....ASK!!
