Well I got it up and running today in the JE Labs baffle.I had it running at just over 40watts I think it drifted up to 41 watts at times.I used a converted pa amp with the valves out.~270volts 20uf/7Hchoke/20uf/400ohm/20uf.I ran it for 20 minutes. At first it shouted so I threw in a 1mh choke.Very effecient and good vocal projection.But nothing really spectacular.Seems to have that thick paper cone sound but who knows.I had to turn it off as the coil was starting to get hot.Hot enough to start getting to hot to leave my fingers on the coil for a extended length of time.So I am wondering if it has a problem or it just cant handle 41 watts.I could definetly smell it to.Hot laquer perhaps.All so one of the voice coil wires seems to go in a coil around the field coil.Iam thinking it probably is a choke.
Any way I have no decent compression driver horns for on top.I do have my pm4a and oris horn.I will get around to mounting it up on top.It almost has enough bottom end to not need a sub in the je labs baffle perhaps not quiet.Should make a good workshop system if it doesnt over heat.I will try lower voltage tomorow.
