Current production EL34 tubes for vtl mb-125

Try Cable Company. They have a large selection of tubes (both new and NOS). They test them all and keep track of the differences in SQ so that when you call them, they can make a good recommendation. Not everything is listed on the web site.

Thanks for all the responses, gentlemen. I agree that the shuguang treasure/psvanes are great, but as I stated in my original post, I'm trying to avoid spending $100/tube. The JJs are certainly on my radar, but I wouldn't know how to choose between el34, e34l, el34ii, kt77 and 6ca7?!

tooblue - I seriously need to update my virtual system. Yes, the mb125s eventually replaced the st150, but there were a few other amps in between. Same for speakers. I replaced the wilsons with quads, but eventually wanted to go back to dynamic speakers, ultimately "settling" on a pair of vandersteen quads. I'd venture that most of the difference between the mb125 and the st150 is due to el34 vs 6550.  BUT ... I HAD to replace my st150, which failed catastrophically in a way that was simply not cost effective to repair - I can't say I did it as a direct upgrade, and there are too many other variables for me to make any reliable comparison.  

Thanks. 

Retubed my VTL MB 125 amps with Genalex Gold Lion KT77.
Sounds much better than the EH EL34 that were in them.

New response to an old response to an even older thread - the Gold Lion KT77 ended up being my solution for the MB125’s too. Took forever to loosen up and settle in, but once they did - wow!  Unfortunately, in the current political climate, Russian made tubes are becoming scarce and fetching NOS prices. I just paid ~$135 for a matched and tested pair of Gold Lion 12at7’s for my headphone amp - they sound great, but $67.50 ea. for a ‘new’ production 12at7? Ouch!!!

Oops, I didn’t see that this was a necro thread when I replied.
