Transmissions stopped/ WE NEED HELP!

Bericht door Caroline »

Last night during transmissions on 48mtrs
our linear amplifier became broken.
It had been any Italian small linear amplifier
with any mosfets and maximum output of
175watts output (not PEP!).

If anyone can offer us any different linear amplifier
with mosfets and any power between 100-200watts
output, please let us know!
Otherwise also any amplifier for 48mtrs with any tubes
and input of maximum 10watts is interesting.
Please let us know!
Many thanks!

Why would you take just any amplifier with any tubes, and not a good one with a specific type of tube?

We need only any new linear amplifier, it rerally doesnt matter, if with mosfets, tubes or specific tubes! :hypo
Only important is that input of such amplifier shouldnt be more than 10watts.

Did you know that this kind off lineairs are suffering and quick failure with long AM transmissions , they are made for Hams with short transmissions and not for AM progams .

Hi Westcoast and Cor,

we had been using nearly the same linear amplifier (but any from Italy) for more than 2 years and it didnt
be any big problem to transmit with it for any hours.
Only problem of cause was too cool it very good
(we had been using any small cooler at the top of it and any very big cooler in front of it ).
Interesting is such price, seems to be much cheaper than such Italian (like KL types) ones.
But we will see what will happen! :r
