I have a TKO 65 from either the late 70's or 80's, amp has problems that take more effort than it is worth, I want to use it as a cab for a little tube amp I harvested and converted from a Hammond organ for a bass and clean guitar recording amp. This amp, the Hammond AO-44, requires an 8 ohm load. I have read in different places that my amp has a and 8 ohm BW, a 4 ohm BW, a 4 ohm Scorpion... Which is it? I have seen the same amp with a speaker that has a shiny aluminum dust-cap, but mine is the one with an all-black cone, dust-cap and all. Anyone know if this has an 8 ohm speaker?
