Sent this earlier, but never saw it posted or a response from John. I
find the 4CX1600's (GS23b's) on Tom Hix's web site - - www.tomstubes.com
. Price $219. Don't know if they are in stock or not, but I purchased
a pair of GU74b's (4CX800's) from Tom last year for my Alpha 99
($200/pr, but there were other dealers with lower prices). His web site
is still active, but I can't tell you anything more.
