** especially considering that the ferrite VHF-attn beads are there to
protect the hv-rf choke's self resonances from getting burned by the VHF
energy that sometimes pops up in the SB-230's anode resonant circuit.

** say the word and I will send you a low vhf-Q suppressor kit for an
SB-230. If it does not evict the squirrels, it's free. If it works, it
is $13 plus postage.
