[ForSale-Swap] Reduction Tuning?

[Keith Densmore]

Greetings to All,
Does anyone have, or know a source of a reduction tuning unit? This is a device that fits over the tuning shaft of a receiver, or whatever, and  provides about  a 4 to 1 reduction in tuning. I know there is something made for Collins 75A series receivers to allow SSB reception.  I actually have a unit here but it's action is a bit rough--I'm looking for something silky-smooth. (for an RCA AR-88). Any help would be appreciated.

73 to all,
Keith, ve3gem
