[ICOM] PBT information- Thanks

Thanks for the great explanation on Icom PBT history, if anyone would know, someone on this list would have the answer.
PBT and a good notch is what makes Icom receivers perform so well.
Gary, what kind of electrical switch contact cleaner should I buy to clean a scratchy volume pot and on/off switch? Rat Shack?
Adam, you know Icom, thanks for adding information about the different radios things I did not know. 
Frank, I can get this mod done for $90 and am told it works just like the original did. About $30 of the mod is for the ceramic filter, the rest labor.  The more I consider it, the more I am inclined to send the radio and get it done. I am hesitant to try it myself and have no business inside my 275H, sure sounds simple though. Also need to install the CW filter in the 275H, sounds simple but I am hesitant to get in there.
