Interesting video with some nice playing. I'm in agreement with the commenters that gave props to the bass and drums, and also with the ones who thought there was a lot of gushing and little technical information given. The hang-tag content is interesting.

I'd be interested to hear what serial number it is. Did they mention if it is running off of 6L6GCs or EL34s?

ODS #125 with 6L6s. Listed for $265K on their website and showing as sold now.

Here is a screen shot of the listing and their pics, which I downloaded.

I think he sends them for repair to Todd Sharp - he mentioned on the AMS rig rundown

Why does the head say 4 ohm load and the cab is 8 ohm?

That’s not unusual for an ODS, where a Twin OT with its 4-ohm secondary is run into an 8-ohm load. With the half-power switch engaged it will be matched. Personally I run mine (which has 4-8-16 taps an no half power switch) into a matched load, which is easier on the power tube screens if it is played at high power.

Anyone know the dimensions, especially the width of the head and cabinet?

That looks an awful lot like a TL806 cabinet or some similar derivative of that, with round duct ports instead of the shelf-ports in the EV plans.

Agreed. From the photos, assuming a 19" chassis width, I'd put the amp cab at 9-3/8 h x 20-5/8 w and the speaker cab at 15-3/8 h x 20-5/8 w.
