Now I understand why the A1834 is one of the most sought after power tubes. It pairs well with the tung-sol 6J5G’s. Loving the combo with my VC.

Man, I want one of those just for the looks.

The TS 6J5G's are pretty righteous no matter what you pair them with, IMO.

Yours should be mullard rebranded with Philips.

Those are my military ones for reference.
They will get a listen tonight


RCA 6as7g warm, punchy , cheap and available. Less resolution than the others.

Tungsol 6as7g is very warm and holographic sounding. But they got quite rare these days. Expert tip.

GEC 6080 is more easily obtainable, slightly warm with good staging, seperation and resolution. Price performance is best.

GEC 6as7g would be holy grail of warm tubes with strong rarity and price. Still slightly behind 5998 in technicalities I must say.

5998 (or 421a) get these and be happy with the best power tube available in your slot. It's the least warm tube of those I mentioned.

Can't say I've ever even seen a Tung Sol 6AS7G?

Hehe when I discovered it's unique and romantic sound I did buy 2 pairs here on Headfi.
Love the sound of these.

I have a 6AS7G tube that makes intense crackling/popping noises after being turned on for a few mins. I tried re-flowing & adding new solder to all of the pins and it's still happening. Before I toss this tube in the trash, is there anything else I can try?

If you have fuse in amp, try to replace the fuse. Very cheap try less than 1 dollar.

Yeah, most of the power tubes that I have paired well with the TS 6J5G's, except the NEC 6080. Somehow, the sound just fell...flat. Probably just need a little bit more time.
Good looking adapter you've got there

Thanks!

I had an NEC 6520...."had" because I dropped it and the stupid glass shattered. Japanese stuff was made pretty cheaply back in those days.

Didn't get to listen to it much before I broke it.....

...but it sounded eerily similar to an RCA 6AS7G for some unexplainable reason.

Yeah that’s too bad very rarely the 6520 would go on sale…

I have some NEC 6AS7’s that I bought from Japan recently, they do have similar constructions as the RCA 6AS7. The prints, some are yellow colored, some are white colored. I bet they sound similar anyways

 

[HTSkywalker]

I tried the Matsushita 6SN7 Japanese tubes, construction is also poor and the sound is less than average

Have pics? Are you referring to the Chatham 6AS7G?

 

[Renexx]

I have 2 pairs of Chatham bottom getter and a Tungsol top getter and both sound the same.

 

[Dogmatrix]

My best pair carry both brand names although they are 6520 , but it does illustrate the familiarity between the two names

Nice I do not understand the 6520 number fully. I thought originally it is the same as 6as7g, but there is currently an offer on head fi for tung sol 6520 and it looks inside as 5998, not 6as7.

I have two 6520s that look like 5998s and one that looks like a 6AS7G. The first two are some of my best tubes for the Bottlehead Crack. Slightly less detail than a 5998 but fuller body. The last one sounds like a regular TS 6AS7G.

I recommend adding one to the collection. Nice tube and quite rare.

 

[DarkDrummer]

This is different. UFO and Saucer are interchangeable terms, but my Svetlana Winged Cs look just like a pill inside a square foil packet,

Some pictures would really be nice!!!

Got these beauties today and I enjoy it much more than the WE421A. It simply ticks all boxes with better micro details, sweeter and warmer mid and pleasant tonality. I am pairing them with WE274A and Marconi B65 in my Woo WA22, and the synergy is exceptional. With these I finally reached my endgame in tube rolling.
