Which of these tubes should I purchase for my BAT amp? 6C33C-B or 6C33C/6S33S?


    Has any one bought the Ulyanovsk factory 6S33S/6C33C.  They sell for a lot less than the Sovtek 6C33C-B.  Are the 6S33S/6C33C the same as the 6C33C-B?

That’s a great deal! I always purchased a couple of extra tubes just in case any were DOA. They never broke during shipping but sometimes there might be a bad one - just like any untested batch of tubes.  The ones I bought arrived in sealed boxes.  Even if all worked fine, it never hurt to have extras. The seller probably can add more if you wish. Enjoy!
Hello yenkochris and steakster,  This is a most helpful post since I have a BAT VK-60 and it appears like it's time for new power tubes, at least.  Did everything work out well with the Russian ebay-er?  If so, may I ask what his/her handle is?  Thank you.
