In Reply to: Re: JJ ECC99 - ?Replacement for 5687 in Preamp posted by dhieber on September 22, 2004 at 15:38:23:
the '99 is very similar to the 5687 electrically. It is the base connection which is causing yo grief. The 7044, 7119, 6900 and of course 5687 all have the same pin-out/basing and similar heater load. at 3x the price of a NOS 5687, I wold not bother with the '99 unless I had a requirement for a 12A*7 based valve and could swing the 1.5-3x heater load...
live long and prosper,
