The EQ's show up on e-bay every once in a while, figure roughly about $100-125. Even then I'd suggest you have it shipped to Thiel for an overhaul. If you were to go that route, I wouldn't let the worry of a few dollars of overpayment get in your way. These are old units and it might take several months for another to appear. Odd thing is they seem to show up in bunches, but, I wouldn't count on that. Furthermore, if there's a choice, consider spending more on the cleaner lookin one. FWIW, when Thiel still had new replacement EQ's for the 3.5's, they were asking $600 each for them.
