Two of these 278CX have nice looking end-bells, the third transformer
has a 1/4" or so crease in one end bell and came that way
new.
They were only run a couple of hours each with 1N4007
recification, cap input filter and a dummy load, having a recified voltage of
about 585VDC with a 3K load.
They are not dead quiet - just the nature of that Hammond unit.
I built a punchy bass guitar amp with another 278CX and 4-6550. Rubber mounting washers might be a good idea.
$58 each including priority shipping for the two with nice end
bells.
$53 including priority for the dinged unit
Paypal works best
Unit 1
Unit 2
Unit 3
Unit 3's ding (not as deep as it looks)
