replacement tubes for jd 502b
« on: 20 Jun 2007, 09:02 pm »
just replaced the stock 12ax7's with tung sol ecc803s reissues and there is a big improvement.  i still have the stock electro-harmonix 6550's and 12at7's.

will replacing the 12at7's make that much of a difference in sound? thinking about slyvania gold brand 6201's - http://www.upscaleaudio.com/product.asp?itemid=32&catid=45
worth the expense or just stick with stock?
