[Amps] Series C in amp output

[Martin Sole]

Amps from Acom and OM, maybe some others, have a large amount of 
capacitance in series with the output after the power/SWR bridge. In the 
case of the Acom 1000 this is 6 parallel 10nF/500v disc ceramic 
capacitors with a 1 megohm (static bleed?) across them.

Have not seen this configuration on older Alpha amps or others. Can 
anyone comment on the purpose?

Thanks
