So I'm still working on this, but I'm pretty set on how it's going to go.
I ordered standard black levant for the tolex:
Mojo Tolex and Tweed » Marshall Style Black Levant Tolex / 54'' W
And salt-and-pepper (basketweave) for the grill cloth:
Mojo Grillcloth » Marshall Style Salt & Pepper Grill Cloth 57'' W
I also ordered gold piping for around the baffle and I'm routing the piping channels as suggested in the refurb shown above. By the way, he had a seperate thread where he shows how to do the channels:

I already have two Celestion G12T-75s that I'm going to put in an X pattern with two Celestion V30s (
Hellatone) much like the Bogner Uberkab. Anyone know how the Uberkab is wired? Do they parallel both of the same kind on one side input, or do they put a V30 and a 75 in parallel on each side? I'm concerned that since the v30s have a 100 dB sensitivity that they'll totally drown out the 75s with they're 97 dB sensitivity, that's twice the volume! Obviously you'd want them running at a different input level to achieve equal sound levels. I can do this in stereo with my Mesa power amp, but then the cab won't actually be stereo since I'll be powering one on each side. See my conundrum?
Someone at another thread recommended this speaker wire, looks like good stuff for the price (it's factory direct), so I ordered the 12 gauge:

Anyway, this thread has mostly been me thinking out loud, but hopefully it will help others by putting a lot of good info in one place.
