Description
This Collins 353A-31 & 353A-12 Plug In Mechanical Filter Adapter Set, is made for the National HRO-60 & Hammarlund SP-400 Receivers.
These Filter Adapters are for 3.1 KC and 1.2 KC bandwidths.
Both look to be in excellent shape and they simply plug into one of the IF tube sockets.
I have and will include the manual.
I am selling them as is, as described for the family of a silent key who was my friend.
