Around a year ago I decided to build a 50's style finger jointed pine cabinet and finish it in tweed cloth. I have always had a yen
for a tweed amp but being a play at home retiree I could never justify
the expense so at the start of last year I decided to take my 1997 green
board black tolex Fender BJr' and build it a new house instead. After a lot of research
and some probably stupid questions I decided on a Bassman/Bandmaster
style cab. As I already had a 4ohm 8" Eminence Patriot 820H left over
from another amp I bought a second one which I wired in series giving me
8ohm. Together with the original Eminence special design 12" 8ohm wired
with a separate jack I would swap between the 2 x 8" or 1 x 12" options
keeping everything at 8ohms. It took me around a couple of months to finish and I am pretty chuffed with the outcome and add some
photo's for the perusal of those interested. Since then I found that I
could get an upgraded power transformer with 4, 8 and 16 ohm options
which would allow me to play all three speakers at once but the guy who I
sent my amps to for the dangerous electronic stuff died and I haven't
found a trusted replacement for so I just play it with either the 2 x 8"
or the 1 x 12" seperately for the moment although truth be told I
really prefer the 2 x 8" Patriot 820H which sound so very different from the Eminence 1 x 12".

Very nice job - it really looks like a mini-Bassman or Bandmaster as long as you don't see the speaker layout.
If you're not cranking it right up it should be safe to run all three speakers - almost any 8-ohm valve amp will take a 4-ohm load without any harm if it's not being pushed into power-stage overdrive.

No mini about it, it is the same size as a 50's tweed narrow panel Bandmaster/Bassman amp 23.5"x22.5"x11" or thereabouts I don't have the exact sizes to hand but that is pretty close. With that speaker configuration and room for the valves it works out to that size.

If you’re interested, I think I have a couple of old impedance change auto-transformers somewhere. (Like a Weber Z-Matcher.) You could use one to run the speakers together at a correct match without having to modify the amp.
