[R-390] HSN 35 Issue

[Perry Sandeen]

List,
Many thanks to all who sent me a copy.
In this circuit Dallas Langford use a $15 ceramic filter instead of the Collins torsion filter that costs $125 in small quantities.
He also found an easier way of attaching in the "A".
I also think it will be adaptable to the SP 600 as well.
With the decreased cost more may want to try it.
When I get a round-to-it I'm planning ti reproduce article as a stand alone doc.
Regards,
Perrier
