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!

For 12ax7, try a 7058 (RCA made good ones). They are cheap and sound amazing.

For 12at7, try a GE or Sylvania 6201.

A very good tube equivalency resource is:
