Well I was debating myself about that, Mike, but I'm not convinced.
What I first thought might be a pair of 811s on the second chassis up
could be MV rectifiers instead. One would certainly expect to see at
least modulator plate meters on a rig like this, and there are two
unmarked meters on the top panel, one with a 500ma scale.
And if you look at the power supply on the bottom of the rack, there
seems to be a lot of iron there, plus four tubes with plate caps visible
behind the perforated metal screen. Yet the seller, who obviously knows
nothing about it, but makes reference to a "very heavy transformer that
goes with it".
Seems to me there's more stuff here than would be needed for a CW rig.
