  Do you have suggestion on c3g, c3gs ? source and reasonable prices?? buy a set or buy 4 to save few bucks?

 
Again $70 for a pair seems to be the going price these days. So if you can find them for less, that might be a good deal.
 
As best I can tell, all C3g's were made by Siemens, so it doesn't matter which brand you get, Siemens, Telefunken, Valvo or Lorenz. Further, these tubes are rated for 10,000 hours, so a pair will probably last longer than your amp. If you can afford 4, you would be set for life. :)

Hi Gravit 8,
 
IMHO tubes that sound good or great, sound good with any kind of music; it doesn't matter classical or rock, so go for the best sounding ones.
 
If the objective is to get the biggest bang for the buck, go with the subminiature Raytheon 6832 and a pair of Sylvania or RCA 6SN7 tubes. These tubes you should be able to get for around $20 total. Then you need adapters and possibly extenders. I am waiting for someone to compare the 6832 to the C3g - wouldn't be surprised if they come close.
 
Read the later posts on the blog and you will find all the info that you will need. Good Luck!

Thanks gibosi. Do you think I can use C3g on my Fisher  500c? I think Fisher use 12AX7 for preamp. You got me all excited about Fisher 500c again which been collecting dust for few years.

The 12AX7 has a gain of about 100, while the C3g has a gain of about 40, so I doubt it would work without serious modification...

I only have 3 hours using these 6080(driver) and they are getting better each passing time.the soundstage opens up  the treble it gets smoother and that bass is deep.My DT880 is loving that deep bass and the smooth treble.

Good to know on the tube sound, wasn't sure if different tubes worked with different genres better, but this clears it up.
So it seems like as far as stock tube sizes go, everyone seems to really like the 6HM5 correct?  Then after that for end game sort of stuff Raytheon 6832 on the cheap, and C3g for best overall? Thanks!

IMHO, C3g's are not alone at the top as the best overall. If someone does not want to mess with double triodes, which typically require an external socket, 7-pin Vector socket-savers and an external power supply, then in my opinion, a pair of C3G's is clearly "end-game". But in order to use the Raytheon 6832, which is after all, a double triode, an external socket and Vectors are required. And if you have gone that far, you may as well set up an external power supply. Once everything is properly setup, there are a number of 6SN7's, E80CC's, E88CC's, and some of the other sub-miniatures, such as the Sylvania 7963, which rival the C3g's.
 
So, if someone wants a simple and relatively clean and neat "end-game" rig, C3g's are the only game in town. If someone is willing to deal with the messiness of external sockets, power supplies and such, the universe of "end-game" tubes is much larger.

Thank you very much for your explanation. How do I go about setting up the external power supply.  Is there a step by step explanation on that on this thread?

6HM5 is very good for the money you pay for them. The Voshkods are also good but then it depends on your set up and the music you listen to. For me, i love my metal tunes and bass so any tube which gives me good bass, i will love them. Thus far, I've had several pairs of generic 6AK5 tubes and RTCs which all sound relatively good. The Voshkods and 6HM5s have very good bass but if you want to move a notch up, the 6SN7 as power tubes will help a lot. After listening with 6SN7s, i cannot return to the stock power tubes as I feel everything seems to have tuned down a notch in terms of dynamics, clarity, bass, etc. And it's a plug and play affair without the need for an external power supply (just need a pair of adaptors). 6SN7s can be had relatively cheap all over eBay so there you go - have fun !

Hi gibosi and Rossliew.
 
Nicely summed up for the majority of LD lovers...
