Also, another reason is that two small ceramic HV caps are usually much
cheaper than one high current ceramic cap as used in the past. Today, it's
very difficult for amplifier's manufacturers to find brand-new high current
RF caps at competitive prices. The size is also an issue for the RF deck in
small cabinets. Anyway, by a reliability point of view, the small ceramic
disc HV caps used today in most industrial manufactured amps for DC blocking
or decoupling, are quite on the edge.

Subject: [Amps] Why do commercial makers parallel up small value caps in pi
circuits?

In many commercial high power tube amps the ceramic caps in the tune
and load circuits are small value, paralleled up to create a bigger
value. Is this because smaller values drift less? Thanks.
