Probably a gassy tube. Nearly all amplifier problems BLAMED on
parasitics are simply gassy tubes.
Replace the bad tube and repair the damage. Anything you do to the
suppressor won't make a bit of difference, except add $29.95
to the California economy. :-)
Don't let Rich know his voo doo nonsense about VHF parasitics
doesn't cure arcing tubes.
