  Loquah, what is the Russian 5998 valve equivalent? I haven't heard of this before.

 
I don't remember the model number - I had to Google them because I wasn't sure if they were a direct equivalent or not. The tubes belonged to @atsq17 so if he's on this thread he might be able to help.

The description on ebay was precisely: 6AS7G Tube. Svetlana Wingged '©' 6N13S 6H13C

A true audio and visual treat.

  Guess us guys in the UK are lucky as the GEC 6as7g is more common on our shores than the TS 5998 and can often be found for the same prices or less than the 5998 (a rarer tube here) goes for.  $65-$85 is not uncommon even for the curved based.

 
I'll trade a nice TS 5998 for a 6as7g brown base.

So happy with how the look turned out for you! Is the Cleartop 12AU7 a good match with the 6H13 and T1s?

Be aware that 6H13C Winged C is out of production and factory no longer exists. They really sound great and if you can't find 5998 or asking price is too high for you get 6H13C

Thanks, it is a very nice tube that is still well priced

I kinda knew they were great since Mahdi had them as his combo and I tried it for a couple of days.
 
With regards to my equipment, I haven't been doing much A-B testing. Just put the Cleartop in the moment I got home and haven't switched tubes since. I might do so soon after the initial euphoria settles down a bit.

I just bought an RCA 6AS7G for 25$ shipped. Seems like a good deal.

I think so too.  A co-worker of mine let me try (and eventually have) a 6H13C, 8702 printed directly below it, and it sounds great compared to a 6AS7G and 6080 that I've tried.  The clarity is still there, but provides a nice warmer tone and I think is very well balanced throughout the lows, mids, and highs.

Have just been diagnosed by a psychiatrist as having bipolar. Apparently part of my manic episodes involves the binge buying of amplifier components, including tubes. Am selling off my entirely unneeded excess of gear as seen in my signature.

Will I never learn?

 

[JamieMcC]

Nathan perhaps I should see a psychiatrist also I have similar symptoms!  
 
Good luck with your sales.

 

[MoatsArt]

Hehe, perhaps Jamie.

Do your buying binges alternate with suicidal depression? Do you put your family in debt to buy things that you don't need or won't use? Do your buying binges occur when you are unemployed because you are too anxious to leave the house? If so, run to your nearest psychiatrist ASAP.

Lithium is to be my friend and constant companion.

It is a beautiful looking and sounding combo. The Svetlana tube is a hidden gem can can be had arround $30 for a pair shipped. I wouldn't surprise if the price shoot up to $50 each in a year or so when stock runs out. That's why I've stocked up on them
