UTC H-22 New
« on: August 12, 2017, 02:27:41 PM »
I was told that the A-25 would be a good upgrade for the output transformers on this single ended vari mu compressor I have. I came across this H-22. What are the major differences in this from the A-25? Would this H-22 be something to consider? Pretty clueless aside from the recommendation I was given from the builder. Right now the compressor just has some tiny transformers  as the output transformers and it rolls off from 300HZ down....

Thanks!

Would work perfectly fine.  H series are pretty much identical to A series but in a round, hermetically sealed case.  But don't tell everyone else  ;)
