Sorry to hear that SO.  That would ruin my day, and then some.

No need to feel bad for the Silent One. We are grounded. Perhaps, I was a bit over dramatic and should clarify, my savings for audio. 

 I'm doin' alright in other areas. The tea tins marked "Audio" will get some cash stashed in them soon enough.

You are right David, an addict never stops!
 
My recent acquisition is a beautiful 6H12C but I am a bit apprehensive about using it.
 
Meantime I am building up a collection of 45's, VT-52's, 310's, 311's and 328's.

 Did all of you convert to solid state?

There are days when it is tempting.

Dw rookie, you're not forgotten (at least not with the use of emoticons) hehe.

Can anyone help identify these weird construction 6sn7?  Got them a while ago but never got the chance to use them yet.  Any info on how they sound?  Thanks.

I disposed a quad set of these while ago, not much information besides supposedly manufactured around 1970's in Russia I think, RFT 6H8C's, either Ukraine or Russia they were for old telecommunications/military use. They sound like the usual Russian tube sound but they last a long time, fairly bland and boring though, you can say natural sounding, high's bit tizzling with some vocals...but the durability do last a long while...some like the sound, some don't but they go for a bit cheaper than cheap Sylvania's. Only reason I chucked out my matched quad was because they all hummed/distorted loudly when overdriven and I got it for cheap $10 for a quad from a Czech Republic tube ebayer. 
 
I prefer the Svetlana's over the RFT's, which are sort of a step up from general cheap Russian tubes with Russian letter prefixes.

Thanks Defqon, I hope these doesnt hum or add any noise in my amp.  If I remember correctly there others 6sn7 with ceramic inside?

No problems. Btw do you still have your LD VI+?

 

[Neogeo333]

Nope, sold it.  Got me a Cavalli Liquid Glass.  Miss that amp, all those 6as7 lighting up the night had a nice view.

Those were actually made in East Berlin. The number 604 and the HF logo both identify the Werk für Fernmeldewesen aka Oberspreewerk in Berlin-Oberschöneweide in the Soviet sector of Berlin. This was the former AEG-Röhrenfabrik Oberspree.

I have some from the different DDR factories and to me they sound excellent.
Nothing in common with the CCCP made 6H8C which sound terrible.
 
They have a double getter on the top and not the flying saucer type getter typical of the CCCP 6H8C tubes.
 
The RFT factories also made the legendary Telefunken 6SN7GTA/GTB.
