WANTED: Kenwood AT-250 Antenna Tuner - UK Vintage Radio Repair and Restoration Discussion Forum

A long shot, but does anybody have a Kenwood AT-250
they no longer want and would be willing to Sell ?

Plenty of AT-230's about, so plentiful, I have one already.
But would like to get my hands on an AT-250 for proper integration
with my TS-430.

Would also be interested in an AT-130.
I fell asleep at the Wheel tonight and missed the one I had be
watching for a week.
Typical!

In case you're not aware of their limitations...

Before splashing out a lot of brass. Consider your antennae. This may be automatic and a beautiful complement to a Kenwood transceiver, but it resembles its earlier and lesser brethren in that it's somewhat limited in the range of impedances it can handle. They can be flashed-over at 100W quite easily, and they don't work well with balanced antennae/feeders, oh, and 160m is usually a stretch too far.

The same goes for Yaesu equivalents and the built-in auto ATUs of current transceivers of almost all makes.
