Good evening all,
Last evening I performed a long overdue cleaning on my L220A's Mid and High frequency level controls. It really needed to be done-the right mid control was causing the driver to cut in and out, and they all had many "dead" areas. I wasn't sure how effectively I could do it without opening up the control, but spraying De-ox-id into the area where the lead tabs protrude through the cases, and into some other small openings seemed to do the trick quite well. However, the left mid control still has an issue, not a showstopper but it seems that it may have some damaged windings inside, from the sound and feel of it. And, it does have one "dead" area remaining that I can't seem to revive. So, I'm pondering the idea of at some point replacing just this one control, since I seem to be in good shape with the other three. It's not an emergency.
Has anyone here had any experience with replacing the network controls on the N220 network? Are the parts available, and if so, how difficult is it to replace the control? From the looks of it, it may not be a job for the faint-hearted.
Thanks,
Peter
