[MAMS] Back On 222mhz with Amp

[David DeVos]

Glad to hear you got it fixed Mark.  I'd love to get a new fan, but I went to 
the Fair Radio site and did not see them listed.  I did buy a new set of bearing 
for the fan from a Canadian fellow on the web, and I will swap those out and see 
if that quiets my 2m amp blower.  


Happy New Year from KF8QL in EN72fu!

I purchased an AM 6155 to fix my AMP. It was not modified so for last couple 
days I exchanged modules and proceeded to do Modes to Different sections and 
exchanged them with what I had. Took 8930 that came with purchased amp and I'm 
seeing 450W most I've seen on band. I'm also operating off of 220VAC which why I 
wrecked the AMP. 


I purchased a Bias module and fan from Fair Radio but they don't look the same. 
I'm thinking that a newer bias circuit was made and manufacture added a small 
board on top of the one I modified. The blower had a board attached to it close 
to the square cage blower. I didn't use them but they maybe good for parts. 73 , 
See in contest Mark, K8MD
