5842 choke loaded (reg psu) RC coupled into 6N15N (EL84) with a custom sowter mumetal >1000hz xformer
midrange - BMS4592nd (midrange only special version) 250hz lecleach roundhorn. Crossover at 3khz LP and 600hz HP
5842 RC loaded into 2a3 parafeed into magnaquest cobalts.
A little off the thread, but James, when you say BMS4592nd, you probably mean BMS4591 because the former model is actually coaxial mid/tweeter unit
and not a midrange only special version. However, if you do use BMS4591 (as I suspect), then you might easily try a higher crossover point between
midrange and tweeter, say at about 6 or 7 khz, where the BMS4591 naturally decays and I suspect the whole reproduction would benefit substantially.
This is what Romy is preaching all the time and from my personal experience I can confirm it is much better than the usual 3 khz co point.
I hope anti-BMS police didn`t notice...
