So it turns out my problem was with the switch, contact cleaner has fixed this for now. Cool to know about the lithium battery, though. Thanks, Roger!
Thanks to rsimms, I have the parts on hand to make a back end for the attenuator and capsule, ala franken-mod, just no mod. That faucet adapter was what I was searching for..... I'll shoot photos as I make this up.
Next issue on the horizon, my pre (9100) puts out around 5.5 volts.... We'll see how it goes, a minimum of money invested on the parts.....
Thanks, all and +t!
Joe
