[GreenKeys] TU filters for 170hz shift...

[Kenneth Gartland]

Hi all!

My thanks to Jack, Ralph and all, for the info and
suggestions for the filter issue(s) of the older
slug tuned filters used in the early vacuum tube
T.U.s...

Are there "Off the shelf" type fixed audio filters
available for the two frequencies used for 170hz?

I remember years back, I had a set of factory tuned
filters from a 43A carrier set which I am sure were
tuned for 2125 and 2975hz respectively used
back in the 850hz days...

They worked great and were rock solid, it was
so long ago, I am sure no one has any of these
filter units anymore...

If anyone knows if pre-tuned filters are available
from a supplier, wud appreciate the info!

Many thanks!
