6SN7 Tube Addicts - Page 216

post #3226 of 4487

So what you guys are saying I scored a good pair of 6sn7?  I saw a similar 6sn7 on ebay but it says b65/ qb65.  Same construction as mine with same ceramic mica.  They even say made in Germany.   God knows why he wants so much for it.

post #3227 of 4487

The very first RFT's were made in Germany, the later one's were produced in Russia or Ukraine, not sure which but there was a pretty lengthy discussion on another forum (think it was Audio Asylum), but from just looking at it, I'm sure those 6SN7's you have are Soviet one's because as I said I had a quad matched purchased from a tube store. I still stick by original impressions with them, they sound just "OK". How much is the seller asking? And also beware of fake relabels - alot on ebay.

 

Btw, do find the MK VI+ not that far from the LG?

The mk6 has power in spade.  It can move my orthos easily.   What the LG bring is fineness and more musicality.   If I use the same tube let say a Sylvania metal base 6sn7w on both amp, the LG sounds better.  But then again the mk6 was designed with 6sl7 in mind not 6sn7.  If I would score both amp on a scale of 1 to 10, 10 been perfect.  The LG scores 9 and the mk6 7.5.  Yes the mk6 is that good for the money.

Right, Soviet sector of Berlin, that is.

True B65s or QB65s must be UK-made by MOV.

Ignorance? Greed? On the other hand, the RFT ceramics are rareish as well.

I have one of the B65s I bought as NOS and tried for a few hours and it sounds fine, but I want to sell it in anyone is interested. Thanks. I'm in NJ.

Yeh it is a good amp, I might attempt to get mine back to LD and have David install the upgraded caps and wiring, I can do it myself but I don't want to risk in having a $850 door stopper or voiding warranty. Although the tube rolling on the LG is any tube rollers dream, the price of the amp 4 times more than the LD though. One thing I know for sure is that it is definitely a very good amp and I find it out performs most products worth more than it such as the Woo's up to WA22's.

Ok thanks for clarifying that, guess some of the stamped codes indicate the plants original NOS and reissues were made from.

If David from LD ever gets a new MK6+ Rev.2 that can handle 6336 tubes and upgraded internals, I am all in.

I finally tried my first 6H12C on my Glenn's OTL.

 

The low end is phenomenal, not bad tubes.

 

To complete my collection I sourced a spare pair.

Well you never know it could happen from what I have heard that their will be another successor amp to the MK 6 and 8 meaning a new flagship.....but seriously for the price the MK 6 is hard to beat....

Lucky you! I may have to source a matched/balanced pair just to try out again, my first experience with them was not a good one.

The 6H12C are not equivalent to the 6SN7 as they have a 0.9A heater current compared to 0.6A of the 6SN7.

The transformer must be able to handle this.

 

After talking to Glenn who confirmed that my amp can easily handle them I decided to buy one to try and the results were good.

 

In a different amp of course they may sound bad, a lot depends on the system.

EDIT: I have read wrong and replied back thinking it was the previous RFT 6SN7 tubes you were still talking about....my bad haha. Btw how's the Glenn?

 

Are these worth the asking price?

They aren't "these".  The price is for 1 tube.  Way overpriced even in this day and age of inflated prices.

post #3239 of 4487

Try the 6f8g variant, much cheaper and sounds better.
