wrote: snip I disagree. A battery backed up electric AI is not cheap, but compared to all of the components in a full vac system, it is, and its far more reliable. Even HAVING a current VAC system does not eliminate that cost, since the MTBF for a vac pump is down below 1000 hours, meaning you are going to have to change it soon in any case. Mine has a couple thousand on it and is still going strong. Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com
