I stopped by Gary's house this afternoon and picked up my Battery Preamp. Went blindly with a custom finish no one else had ordered so far, leopard wood - and I'm actually quite pleased. It's not far off from the Teak of my Spendor SP1's. I'm still not sold on 'wood' facia / trim for audio gear, but it's growing on me.
Feels odd actually. I know for a fact I can only do a little better, little worse - the buck pretty much stops here. Could this be the last preamp I buy for the reference rig?
Uses 2 banks of batteries, each bank is good for 12-16 hours playtime, and when one set is drained, simple flick of the switch to the second set, and first set begins a 'smart charge'. Tube compliment is a pair of 6DJ8/6922. I've got some Westinghouse 6922's in there right now. Another neat thing, it uses one 1 triode of each tube, for each channel. The left channel uses the left triode of one tube, the right channel uses the right triode of the other tube. So what, right?
With the low voltage Gary is running the tubes at - the single triode should give 10,12, even 14,000 hours of playtime. If for some reason you listened enough to use up that triode, simply SWAP the left and right tubes - and use the 'other half' of your prized 6DJ8's. That is forward thinking friends.
Anyway, listening time awaits......
