I have for sale a newly acquiered Trace Elliot GP12X Preamplifier for sale. It is in very good condition cosmetically and fuctions perfectly.I recently opened it up and checked inside and everything was perfect. it was dated 11-9-89 I used it with my New 715x combo which has the new ah500-7 head in it. With the Gp12x connected it was more crisp and defined than the one in my combo. I am only selling because trace elliot gas is expensive gas and what i im trying to get, i hope, will have as clean as of a sound plus more. comes with power cord and copy of user manuel. $$150 shipped. local pick up ok.
