[R-390] R-390a mechanical filters at Fair

[Anthony Casorso]

Roger (AI4NI) was kind enough to confirm for me that FairRadio has mechanical filters for R-390a even though they don't show up on their web site. He suggested that I email them and find out.
Here is the reply from FairRadio:
"Yes we have mechanical filters for R390A
, 2 khz is $85.00 plus shipping
4 khz is $80.00
8 khz is $65.00

Just in case anyone was wondering.
