I like the 60s and 70s producution on the 6N13s best but 80s still good. I find them one of the more consistent of the Russian tubes and also one of the great Russian tubes that hasn't been 'discovered' yet. Unfortunately pricess of 6N23s have gone silly recently. let's hope that doesn't happen to 6N13s 60s production..

I bought this Svetlana Winged "C" 6H13C for $6/tubes awhile back and now these price went up.

I'll give you that. But at least to my ears, it sounds a bit better than your average oil rig.
 
Cheers

Hi L...you wouldn't believe what we all got up to on the LD Rolling Guide over the past year!
 
And the upshot for this project (luckily) is that we discovered what others already knew...the wonders of 6SN7s and 6AS7Gs...

Well folks, having been enlightened by enthusiasts more experienced than I, it looks like I need to review my opening statement about "replacing the 6N13S with our own favourites"...
 
Although I'm sure this may still apply to some of those with stocks of various flavours, I obviously undervalued the qualities of the Svetlana "Winged C" in particular...I stand corrected!...(Sorry there's no smiley for "eating humble pie" lol!).
 
Further to the last update from the Feliks guys and the decision to use 2 6SN7s, there has been a query as to just how this helps re low impedance 'phones. So I am hoping for further clarification on this subject...should be quite interesting...
 
I had asked that any saving by using just one might go towards higher grade wiring/caps etc. Lukasz replied that using 2 would not hike the cost unacceptably, and that they already use very good quality wiring and components. He emphasised that quality was paramount to their products...which has to be the deciding factor in such a crowded market, and especially to keep ahead of Far East competition...(and which is why I approached them in the first place!).
 
The clock is ticking...

A sub-miniature 7963 very elegantly stuffed into an octal base....  
 

 
A pair of C3g's....
 

 
A 25 Volt 1633 (25SN7)....
 

 
Two 9-pin 6DJ8's crammed into 7-pin sockets, using only one triode in each bottle...  lol 
 
But of course, I wouldn't dream of doing anything like this with a Feliks amp.. Maybe....

 

[Lorspeaker]

gibosi... u should start your own production of exotic lukg amps

 

[gibosi]

Lorspeaker...  Thank you for the vote of confidence... But I don't think the world is ready yet... lol

  WHilst we are waiting...may i ask a noob question about rectifier :
 
I have rectifiers like 5U4, 5Y3, 5AR4, GZ32, GZ34 ( used on a Decware Csp2+ )...
can such rectifiers be used on a 6AS7 slot...and vice versa..say with an easy addition of an adaptor? 
Any danger?  Or i should just keep them apart? 

whilst we are waiting....
 
Anyone knows what are the reasons why some ampmakers use one category of rectifiers such as 5U4,GZ34 etc..
and another amp maker would want to use 6AS7s? 
( got to do with european std vs usa std?? or sound or voltage or ??? )
