What's the best sounding replacement for 12AX7A and 12AT7?


My amp is a Jolida 502A - Currently with stock preamp (12AX&A) and power drivers (12AT7) - I did upgrade to Svetlana 6550's for power ouputs.

I'd like to get a little more bass without getting sloppy!

Talk with Andy Bowman at Vintage Tube Services (www.vintagetubeservices.com). This guy is the real deal! His supply, service, knowledge, testing expertise and equipment, and experience make you realize that all of the other so called "experts" really don't have a clue...and I've dealt with most of 'em.
