This is my second set of "Twins".
I Acquired these as a complete set with both power supplies from a friend who was passing them along from SK's estate.
They are in pretty nice condition.
...and I'll be keeping these. Don't know why I sold my first pair, they worked well.
These will fit right in with the other sets of twins I have.
There were no cables or connectors...
... so I made up a set, and found an old TV cheater cord on the bay for the transmitter's power supply.
This is how the power suply was mounted.
I presume there was a corresponding "rack" in the vehicle.
It also came with documentation, a real plus.
This is the first set of Twins I owned. I used them for quite a while and then for some strange reason, I sold them about 6 or 7 years ago.
