Morning Folks, Just wanted to give everyone an update on the cleaning of my Moto 1500 series dup.s. I have to very respectfully now Skipp ;-) . disagree on cleaning of the cans. I know a lot of the Moto techs don't worry about it but I had the fun of working with several cans now that either was cleaned but not properly (by me none the less!), some that were not cleaned and a set that was cleaned to the hilt. All of these cans were on line within the past couple of weeks. Also all of these were put dead on the money with the proper equipment before being put into play. I just really wonder since it is a type of inductor / capacitor. We do live and learn and this was my experience J
Easy way to clean these cans and the result was about 80db in separation with no desense. Running about 110 watts into the cans. Works wonderful now. Even with the repeater in a "hole" 300mw on an ht is not bad. I used Tarn-X and a GARDEN HOSE! In the main part of the cans, pour it in, hold your hand over the open end and "slosh" it around. Be aware, it will leak out the holes. The more you "slosh" the more crud will come off. Be sure and use rubber gloves by the way ;-) Also after a 2nd try in cleaning with Tarn-X, I will say follow the directions. DO NOT LET ANY PART BE WET WITH ANY TARN-X FOR EVEN A MINUTE. Also, don't re-use the Tarn-X (over a tub and re-use it). I found it will look uglier than it was before if you re-use the stuff ;-) However, use a small tub to "slosh" the parts around. Just be sure and pour it out and wash out the tub with a hose after each part. I did find even doing this, some of the Tarn-X did not come off (just a few droplets here and there). Those spots will turn dark and nasty over time. GET IT OFF. Especially if it is on the plunger or fingers. I used forced air to get all the droplets out of the cans and their parts. Then I used a little Brass-O and a Silver/Copper/Brass cleaning cloth (one of those ones that is treated with the chemical stuff and also has a polishing cloth). With the plunger itself, shine, shine and shine! Makes tuning even easier if you do. Do what you can to get all the rust or crud off of the plunger rods. DON'T give them a "hose bath" they will rust ;-) Coat the threads with a silicon spray as well. I used ACF-50 (http://www.corrosion-control.com/acf50.html) in a light coat over every part of the cans. Don't expect this stuff to dry, it won't. If it is too heavy of a coat, use a light cloth to take off the excess. Also acts as a lubricant on the fingers and plunger. Using the Tarn-X does work great and is MUCH easier than just the brute force of polishing it with Brass-O or something along those lines. 73 and have a great weekend, Robert
