Did some testing today. Follwing the Doctor's "3rd whatever" I put in two Svetlana 12ax7's. Third Svet is on backorder. I guess I'll have to wait to get the third one to hear the benefits that the Doctor talked about.
I did take three of the GT12AX7M's from Marshall and toss those in. I liked the tone.
The output with the GT's dropped a bit, but the amp broke up a lot quicker.... Great if you don't want the clean head room.
Wouldn't mind having the best of both worlds, headroom with the breakup. I suppose I should try just one 12AX7M in the V3 position and see if that does it.

Interesting. This is the first time I've heard anything positive about the Svetlana (SED?) 12AX7. I wonder if they've improved the microphonics situation. Mike K www.kcanostubes.com

Got the third svet today so I popped all three in. Sounded nice, a little warmer just like Dr.Z stated in his "Third Whatever". Got some good tones all over the spectrum. Now I just need a Z-Break so I can crank the heck out of the pre gain.

The Svets are tung sol... Let's clarify. Do you mean that Svet 12AX7s are the same as the fake Tung Sol 12AX7s which are Russian tubes from the same company that brings you Sovtek tubes who bought the trade name "Tung Sol" (a highly respected name in US made tubes in the '50s and '60s) and now uses the Tung Sol name on their Russian tubes? ;D Are you sure about this? It's annoying when rumors are spread on the net. Mike K www.kcanostubes.com

My mistake, I often get my Russian names mixed up; Xpo-Pul not Tung Sol. The following exerpt is from: www.wingedc.com/---------------- JSC Svetlana is a Russian company that owns and operates the Svetlana factory in St. Petersburg, Russia, which has been making vacuum tubes for almost a century. These tubes have been known in the United States as Svetlana brand tubes and have had the "S" logo and/or the logo (a Cyrillic S) on them. Because of a change in ownership of the former American distributor, JSC Svetlana recently lost its ability to sell vacuum tubes bearing the "Svetlana" name, while maintaining the ability to sell the tubes bearing the logo in the United States and Canada. The Xpo-pul factory (formerly part of Reflector) in Saratov, Russia is an entirely different Russian company that makes vacuum tubes for an American corporation that controls the Sovtek and Electro-Harmonix brand names. This same American corporation now also owns and controls the Svetlana brand name in the United States and Canada and recently introduced a line of Svetlana branded vacuum tubes produced in the Xpo-pul factory. The Xpo-pul factory "Svetlana" tubes are not the same Svetlana tubes that you have been accustomed to over the years! Rest assured that the Svetlana factory in St. Petersburg, Russia is still producing vacuum tubes and has no plans to stop. All current production St. Petersburg factory tubes -- and only those tubes -- do bear the mark, while in the past some did not. In today's world if you want the tubes that you've come to know in the past as "Svetlana", the only way to be sure you're getting that tube is to look for the mark.
