Hi all,
in 1989/90 I bought a Landwehr Electronics preamp for 70 cm band and all
was OK till now.A few weeks ago,for some reason,( may be an electrical shock
during a storm ) the GaAsfet decided to die.
Unfortunately it is impossible to read the name of the GaAsfet to be replaced
and on Landwehr technical sheet for 70 cm preamp,the GaAsfet is listed as IC
with no particular specification.
No useful answer to my e-mails about the type of GaAsfet used from Landwehr
El. in Germany.
So,I hope someone can help me to find the name of that GaAsfet, I would
appreciate.
Thanks.

Hi,
Take a look here http://www.radiodan.com/ted_stuff/landwehr.htm which may be
useful. "Radio Dan" used to sell recondition units, and the GASFETS for $19
USD. You may be able to get one, or find out what a suitable replacement
is. Good luck! They are great units.
73s,
