[Amps] amp reading

[Alek Petkovic]

I use 5 Watt wire wound resistors of 0.1 and 0.22 Ohms and 
series/parallel a heap of them up to get the desired resistance/power 
dissipation level.

You gotta overkill on the power rating because you don't want them 
getting hot and you often can't mount them in a cooling air stream.

I learned a whole lot by finding www.somis.org (AG6K Richard Measures site including kits for suppressors on various amps) and www.w8ji.com Charles T. Rauch Jr. sites (what a station!). I put one of Rich's suppressor kits in my Dentron MLA-2500 "basket case" amp trying to improve it. I'm not proud of my 'construction' technique (read the whole instructions before starting) but I'm sure it helped. One of the things I wonder about is how you add a resistor to the filament lead since it seems it is going to have to be about 0.2/0.4 ohms or so at high current. Maybe a wire but that can add inductance so I was never clear on that. I suspect my Dentron could use that mod but I haven't done it yet.
