Does anyone have a data sheet or manual on this item? Palomar advises they no longer have any files on this device.

Are you asking about an Impedance Matching Balun Transformer, model PB-X (where X is a number between 1 and 16)?
If so I have a 1991 catalog that has some data on it.

Clint,

It appears to be a matching transformer built into a 2" PVC Schedule 40 cap. I has 5 SO-239's and an apparent input of 50 ohms with output combinations from 32 to 5 ohms based on jack mateup combinations shown on the face plate.

I vaguely remember those but it is not listed in my 1991 or 1993 catalog -

Sorry -

I just picked one up at the Findlay Hamfest.  This appears to be the same as a multi-ratio unun in Cebiks books.
