[UK-CONTEST] Dressler D 200 s VHF Linear Amp

It's not particularly easy to alter the gain of the valve, which I think is
a 4CX350. So you need to adjust the power from the transceiver that you are
driving it with. Yes, you can "underdrive" it, any amount you like.

Hi All

I have just got a Dressler D200S VHF Amp for contesting and general chat 
on 2
However I'm wondering if I can underdrive it or turn it down somehow to 
give out 150W

There is a attenuator pot on the back as well as a high/low switch to 
turn the attenuator on.

The input power for full power is 10-12w drive for anything from 400 to 
1KW out on SSB

Thanks
Will M0GYZ
