[UntilThen]

Ting Feng 6 never heard of it. I prefer the looks of bigger tubes but having not heard that I wouldn't pass judgement on it. I know they have the capability and capacity to make good tube amps if they want to. Nice styling though but I bet it's quite expensive.

A bit expensive than Elise. Cost around £750.
 
Another famous China-made tube amp under £1000 is called Jingbo (金波) GA5. Guess these two are the main competitors and why no one pay attention to the Elise I just posted. 

 

 
I should stop posting these irrelevant pictures, I have my Elise LOL, can't ask more. I also like big tube look

  @hypnos1  price has dropped for these Visseaux EL33. I reckon you should include the EL33 in your tubes shootout. 

 
It'll be Austrian vs German vs Australian vs French.

I assume I would need adapter for these, power or driver  Also if tubes are NOS how come pin in front next to keyway, is bent? At that price you would thing he would have noticed and straightened it

It's good to know the competitions over there. I've never heard these 2 brands before. Only familiar with Darkvoice or La Figaro and Little Dot.  

 
I wonder what tubes are used in those tube amps.

You have a sharp eye CF. 
 
Definitely need adapters. These are pentodes with different pin connections. They would have to be wired to 6SN7 as strapped triodes in Elise, similar to EL3N. 
 
So we will await @hypnos1 as he barricade himself in his chemistry lab while we provide him with all encouragements.

Just for you UntilThen
 
For GA5 :
 
Two tubes of 5814A or ECC82, Four tubes of 6P14P or EL84.

 

 

 
 
For Ting Feng 6:
Four tubes of EF80 while 2 tubes of 6AS7G, 6080 and equivalents.

News Flash, just saw on television reports of two Joey's fighting over loud music in desert, Apparently, stolen LP's from mail delivery resulted in loud music, tone arm ripped from the plinth, What in the world is gong on down under???

Ah ha... those are respectable tubes.

But your 6080 is something else, it has YM and YK after the 6080, what does YM and YK stand for? Is it a Mullard's 6080? 

As for my Mullard 6080, I've no idea what YM, YK means. I take it as 'your mileage' 'your kinks'.

Hi H1,
 
You forgot Ingmar Johanson among the boxers. Quick: which Swedish manufacturer made vacuum tubes?
 
What is their designation of the 6SN7?  (Hint - it has GEC status among collectors)

are you referring to the ericsson 33S30B?   & by gec status, you mean like the set of 6 used, untested which sold for $2768 us ~ 2 yrs ago on the 'bay?

Suddenly thinking about Elise maintenance
 
Quick and newbie questions :
 
Since I had that unexpected bad tubes, I might counter that situation in the future again:
 

1. Will bad power tube or driver tube cause damage on tube-amp or headphone in Elise’s case?
2. What if leaving the bad tube on the amp for a while without notice, will it cause a serious problem to the amp with the time goes on? 
3. Does Elise have any protection like safe fuse preventing the bad tube causing problem to Elise amp itself?
4. What shall I be careful in the future?

 
Edit:
 
I just found some answers from some experts:

Hello there
Congratulations with your new kid.
I had that same problem (I think). After several weeks I found that was cd player that transmits that noise, specialy when changing tracks. May be your problem is the same thing. Easy to solve

Hi G49,
 
Excellent! You pass the test with flying colors!
 
These 6SN7 tubes were made for WWII artillery pieces and made extremely rugged with five support rods and triple micas.
 

 
These tubes were used in the aiming device of Howitzer cannons.
 

 
One source states that it was a Telefunken tube made under license, but the same page also says under license from RCA. The actual tube was made by Standard Radio Fabrik (SRF) - Standard Radio Manufacturing.

A sister tube, the 6SL7 or 33S29B, recently sold for $1200 for a pair.

According to @pctazhp's experience, Mullard 6080 is nothing similar to GEC 6AS7G, thus I go for the Mullard 6080WA since some review suggests 6080WA has the similar sound to GEC 6AS7G. I might purchase another pair of GEC 6AS7G next month in UK to compare it with Mullard 6080WA in order to confirm whether they are similar or  not, find a reliable tube supplier, will be more expensive but will save me some energy to worry whether it is authentic or not if buying them from China.
 
But your 6080 is something else, it has YM and YK after the 6080, what does YM and YK stand for? Is it a Mullard's 6080? 
 
Again, Elise thread is the best thread ever I've come across on head-fi. You guys are just so helpful.  Very satisfied. 

 

I need to clarify. I've never heard the GEC 6AS7Gs. I said the GEC 6080WAs I ordered didn't sound very similar to my Mullard 6080s and were much better in my opinion. I did mention at the time that the seller claimed the GEC 6080WAs were 95% of the GEC 6AS7Gs, but I have no idea if that is true or was just pure hype.
 
I really love the GEC 6080WAs running with EL3N drivers. It is the best combo I have tried by a significant margin and is all I ever listen to any more - regardless of genre or my mood. Candidly, my eyes pretty much glaze over now with all these new tubes that are popping up. I enjoy reading about them, but I'm really burned out on tube rolling and spending more money on tubes.
 
Because the RCA 6080s are generally pretty cheap I might give them a try, but honestly the thought of opening up one more box of tubes right now is not very appealing to me. Listening remains very appealing.
