[R-390] question on "dogbone" ceramic caps

[Steve Toth]

I'm troubleshooting the BFO circuit in my R388 - plate and screen voltages and resistances are off - and it uses ceramic dogbone caps as bypass capacitors for the plate and screen circuits.  Do these stay fairly stable or are they prone to go leaky?  I'm trying to figure out what parts I need to possibly replace in addition to the plate and screen resistors.  Thanks.
