Since someone asked about filters, I am reposting this list, and once
again asking for any more information you may have to fill in the gaps:
Ten-Tec IF filter data
Model Number / Stock Code / Bandwidth Hz / Center frequency MHz / Poles
Following the number of poles are other numbers that have been reported
seen on these filters. They may be date codes or PCB design numbers.
