I'm the second owner. I bought these from an electrical engineer who built both mono blocks.
The current 300B power amp sold by Bottlehead has gone away from seperates and is a Stereo chassis. The advantage is it can be bridged into one amp, but the advantage of this amp is that it can be rewired to use 2A3 tubes if your speakers are sensitive enough and you want the upgrade. The current single-chassis 300B power amp is $1,849 for the kit plus shipping from Seattle, so these are a great value.
Asking $1,000 + shipping from San Diego. These will be professionally packaged by a shop that I've used to ship dozens of audiophile pieces.
