im looking for a cheaper NOS 12AX7 for V2 in my 5E3. Another RCA 12AX7A I bought turned out to be bad, which is really frustrating bc this shit is expensive. I'm not gonna mention the vendor I bought it from because it's popular and I'll just get crap for it. Any suggestions on brand? Right now I am using a preferred series tubestore 7025 in V2 which actually sounds very good.
