14 inches deep. Any deeper affects running the power cord and input jacks, having to unhook it just to put the back cover on using a standard 16 inch rack case.
Agreed - 14" sounds about right. I think the triaxis is 14.3" and I recall it being about as long as you would want anything in a guitar rack, and if I recall correctly sometimes I had to unplug jacks for SKB-style shallow racks. As for moving to 2U that negates the whole point - I currently use a MESA 20/20 since I simply can't add any more rack spaces and still be able to lift my rack by myself and I don't need any more power than 20watts. Not to say there wouldn't be a market for a tricked out Egnater 2U - but I think that's a different market and one that is already relatively competitive, including the Eggie-designed Randall.
As for stereo vs. mono - like the vast majority of guitarists I never run stereo live (both because I don't need stereo and because it's not practical to get it mic'd up to the PA and properly mixed in most settings in which I play), so having two channels is a benefit only if I can make them sound different. And most guitarists who have the luxury of running stereo also have the luxury of roadies and more space and therefore don't need to limit themselves to a compact, lightweight amp.
Although having different power tubes for each channel would be ideal, even having different voicings using the same tube set would be awesome. After experimenting over the last few years, I'm convinced that power tube types don't necessarily mean as much as most people assume. For example, IMHO an EL84 power section doesn't necessarily sound like an AC15 and an EL34 doesn't necessarily sound like a plexi! I suspect that having remotely switchable feedback attenuation controls and/or power scaling or other voicing/tone-affecting controls would be of more value to most guitarists (whether they think so or not!) than being able to run different tube types from the same amp. I'd love to have the flexibility of the power section of my Stephenson 40-watter (one power amp with selectable tubes, variable feedback attenuation control (to me this is the 'secret' between vintage voicing and more modern sounds . . . ), variable power scaling) in a one-space rackmount amp so I can go from squishy/saggy AC15/tweed deluxe type tones to plexi type tones on the fly, but if I had to give up one of the F.A.T., scaling, or tube selection controls, I'd give up the tube selection (and I'd probably go with EL34s if I had to choose just one, though I suspect that EL84s are far more feasible in a one-space unit).
And while we're talking about the 'perfect power amp' - it would be ideal to have the ability to either (i) run a different cab from each 'channel' (e.g., a 4x12 on one and an open-back 1x12 or 2x12 on the other), or (ii) run them both into one cab (i.e., switching between two different power amp channels into the same cab).
All that said, just having a one-spacer that has the features of the MESA 20/20 but better/different tone I suspect would have a good market given the dearth of one-space rack-mount power amps out there. I'd buy it!
