First, my current plan is to replace the Bash plate amps/xovers with a nice EL84 PP amp with around 14 watts. Of course I will then need a pair of passive low pass crossovers (I will need help here guys) at probably between 150-200 Hz to blend with my Lowther PM2MKII's. Now, before I get to that point I will run the TT's full range next to Lowthers to hear if there is an obvious volume disparity between them. If so, then I will likely stick with the plate amp/xover with it's volume control. Things may not be so simple though. The Lowthers may be several db's higher in efficiency,but, at around 200 Hz and below they are likely down more than several decibles from their specified efficiency while the TT's may well maintain their rated efficiency at those frequencies. It would have to be pure luck (or baffle size maniplation) for these different drivers to just happen to volume match naturally at 200 Hz but I am hopeful. I assume that the TT's will drop a couple of db's through a passive filter so I am hopeing that they are somewhat louder than the Lowthers at 150-200 Hz. Any way, I reeally would like to go the tube amp/passive route rather than the current compromise of an inexpensive plate amp.
Also, I have become sickened by the often overblown bids for Ebay amps such as 6BQ5 eico, pilot, fisher, Dynaco amps etc. If any one has such an amplifier that I may acquire at a fair price it would be greatly appreciated. I wll of course need 150-200 Hz tones because there is no way to compare their volume levels without strictly narrowing the sound to them.
