Carl:
I found that even with one of those filters and an ICE BCB filter both in
line that I still had Arc Fault problems with my Orion II. It turns out it
took two things to finally fix it. First, I sent the radio back to Ten Tec
where they discovered there was a bad bias pot in the final. That fixed
most of the problems, but the circuit in the ACOM 2000A, which I believe is
the same as in the 1000, was way too sensitive and had to be modified. I
shunted R132 on the Interface board (100k Ohms) with a 47 k Ohm resistor.
R132 is found on Sheet 7 of the schematics in Appendix A of the Technical
Supplement of the 2000A. It may be in a different location for the 1000.
No problems since, unless there really is an arc, in which case the circuit
still works as it should.

Subject: [TenTec] Looking for special filter for Orion and Acom amp
I now again have an Orion and I also have an Acom 1000 amp. The Orion
sometimes causes a false arc fault on the amp. Tentec used to have filters
that they gave away to fix this problem.
Does anyone happen to still have one of these filters that they are willing
to sell to me?
