[Elecraft] KPA500 & Drake TR7

[Marcel Jorba]

 Thanks to all of for your prompt answers
On CW it works great thanks to the carrier adjustment control

On SSB: it goes to 150W out very easy
Yes it is just for fun.
The K3 is great but the TR7 is funny and special.


One last question: Someone suggested to use a 9V battery  with a pot to inject a constant negative voltage in to the TR7. But any idea about the maximum voltage?

 Greetings from Barcelona
I have here a K3-KPA500 setup that runs great
I also have a TR7 and I am thinking about using it together with the KPA500 The obvious problem: The TR7 delivers a lot of watts (200 pep).
Is it an idea to discard? Or is there any reasonable approach to? ALC control is not a good idea I think
As an alternative (500-1000 W), is there any small (in size) linear to consider? I don't want to go back to the big tube linears. The KPA500 is great for what I want to have here.
