[R-390] Rebuilding Service for R390A Mechanical Filters

[Paul Dulaff]

I am polling the R390 list community to see if there is interest in a rebuilding service for the R390A mechanical filters. This service would provide rebuilding of the R390A filter by cleaning the filter of all disintegrated foam material, rewinding all 4 coils with new wire, installing new foam material and reassembling the filter. The filter would then be checked with a network analyser, with both this data and the filter returned to the customer. The fee would be $125.00 each per filter. The customer supplies me a rebuildable core.

Basic steps:

Inspect filter
Disassemble and clean all internal parts and the bore inside the filter body
Rewind all 4 coils - new wire
Reassemble filter
Check with Network Analyser
Supply customer with filter and data

Please let me know if you folks have any interest.
