Just a cap will do.
I don't know which schematic you have but changing the .22uf cap that feeds the 300b to a .022uf cap will increase the frequency of the high pass filter from 2.2Hz to 22Hz
That might do it.

- Don't you think that 0.22uf and 330,000 ohms and driving a 300b hard is a pretty obvious problem? - Chip647 12:26:24 05/22/15 (3)
