When restoring the old tube equipment (tube receivers ) does it make any
difference if the old paper capacitors are replaced iwth the ceramic
disk or should another type be used ?

I know for RF one needs to use capacitors that are rated for rf but in
the audio stages does it really matter what kind of capacitor is used as
long as it is the correct value ?

Reason for asking is that I bought an old receiver that someone has
replaced many of the capacitors. The book says pape capacitors for some
but they have been replaced by the ceramic disk type.

The author use a 5 digit "Gen Rad" LCR meter to demonstrate differences in various types tempcos.
