A better source... Buy the 100 watt UHF Mitrek Mobiles when you can find them. The PA is a near exact duplicate of the MSR UHF 110 unit.
After having done it many times... it will still take you at least 2.5+ hours to do the swap if you have every tool and trick ready to go. I wouldn't quote less than 3.5 shop hours to do one. The transistors are integrated and sold only as modules each and there should be at least 3 of the final high power modules in your PA. The module kits are/were not cheap from Motorhead. Good luck and get your specialized tools out. Don't crack the white substrate material or you can trash that entire section. BE SURE TO CHECK THE HARMONIC FILTER... it's probably bad and in many cases the source of the pa failure. cheers, skipp skipp025 at yahoo.com > "kk2ed" <[EMAIL PROTECTED]> wrote: > > Good Afternoon, > > > I have an MSR2000 UHF 100w PA that died.
