C. 50 + 50 uF in B6CA38A (Techniek Radio/TV)

Do keep in mind
That an electrolytic capacitor usually degrades when it has not been in use for a long time.
Which means that the vèrry thin layer of aluminium oxide that serves as diëlectricum needs to be "reformatted"
This degrading of the diëlectricum makes the insulation value of the capacitor poor;
measuring the microfarads value gives the (wrong) impression that this increased
But anyway, from 50 uF to 70 uF is not critical; rectifier tube may have problems when you increase to more than 100 uF
