HazBeen Posted April 4, 2012 Share Posted April 4, 2012 (edited) I just stumbled upon a very very well priced Power Amp that I have been after for a while. This means that I may let my QSC PLX1804 go. Bought not very long ago (about a year) from Thomann for around GBP700,-. Has probably seen around 30 gigs, no more and has been rack mounted all the time.
