[TenTec] 540 Mic wanted..... Or is a new one better?

[Larry Greenberg]

I am looking for a mic..  If I can't locate one,  I will just have to order a new mic from Ten Tec.  Even though old this is my main station rig.. It is mint ...  Right now it's at the factory getting the once over.  Am I better off trying to find matching mic or will  I be better off buying the new condenser style withh the 9 volt batter from TenTec? Thanks Larry N5BEA.
