Hi, I want to buy this amp. http://mimimuzika.com.mk/index.php/...zael/2011-11-30-14-37-31/3263-0217360000.html The price in the shop is approximately 2000 euros. However I guy is selling to me the same model for 1000 euros. The amp. is 5 years old and it still have the original tubes, so I guess soon or later I will need to replace them. The guy is a wedding band member so the amp. is played 3-4 days every week (not counting when he practice etc...) I was at his place and I looked the amp. and on the surface looks like brand new. The sound is also as it should be, but since I have no experience with this good and expense amps. can you tell me or give me any advice what to look/check so that I dont get f***** up. And also, id the price of 1000 euros good for 5 years old and this kind of amp?
