Philip, I have numbers of RBs that I thinker with and from what I have seen the higher voltage the better. If you search time nuts I have commented several times that a tired circa 1994 telco RB seems to be in the 2-3V range. The give away is if it loses lock randomly and I use a pedometer count loss of lock. Gives you a clue if its happening. Regards Paul WB8TSL
