Radios4you has some of these up on eBay. Normally, I don't buy from eBay,
but this was a good deal. He has them advertised as the boards for the
HF-250 but when I e-mailed Lowe UK, Tony told me that there was only one
board made, the W225 preamp board. I think what fooled Frank and myself at
first was that the component layout is slightly different from the older
iteration.
I compared this board to the schematic in my HF-225 service manual, and
with the exception of the additional 22uF cap they are electrically the
same.
I installed it my my HF-225 last night and it works like a champ.

Hi Pete- excellent find. I saw them too.
With all the discussion on the group about active antennas, this would be a
good opportunity for the homebrewers out there to build up an active antenna
with these Hi Z in preamps as a basis.
