Has anyone compared RCA 6AS7G to 6AS7GA ?

Thanks in advance.

Got lucky and scored a GEC A1834. Have a pair of Mullard CV 2984 coming too, so I should be good for a while? Who knows until the next tube?

Once you get the GEC tube, your search for 6AS7-type tubes will be over

Hey Rob, that is not entirely true. I listened to it at the last Seattle secret meet and it made it possible to listen to Kingstyles Woodied recabled DT770's. Very lush sounding tube. Very nice. What 6as7 would be the opposite? One that would have a kick in the pants sound, something that would rock out with The Rolling Stones?

a lot of good info here. Subscribed.

There seems like a RCA with metal base and black plate.

Are these same in terms of performance?

To me, that's the 5998

Bought a NOS 6as7g froma local shop; it makes a loud popping noise in the first 20 minutes or so but seems to be working fine otherwise. I don't have a tester, but does this mean I got a dud?

amp is a wa2; one of the 6as7g tubes came to me broken so I bought another unmatched nos rca tube (above). Also have one 5998 tube that's good and another with broken glass in it

I'm off to a bad start lol, should I just sell the onesies I've got and start over?

I don't think so. My Chatham 6AS7G makes a lot of noise like this - microphonics - for the first few minutes, but otherwise sounds terrific. No biggie. And some tubes do get bits of loose glass in them, also doesn't necessarily mean it's a dud, but you should check for obvious damage to the structure.

A tiny bit of glass on the INSIDE of the tube is not generally a problem. But a LOUD popping noise is. A slight "pinging" sort of sound is indeed microphonics, and is OK as long as it doesn't bother you too much.

Just scored a Bendix 6080WB Now I may stop collecting for a minute

That's a pretty nice tube! Do you like it?

They are rated identical. GA is a straight bottle style. I have lots of both and they sound the same. It's a matter of taste IMO (if you like the coke style bottle and if your chassis can accomodate the larger size)

6AS7G tube with metal base? I have not seen one yet. They are available on the 6080 and 6AS7GA. And I thought I have gone through every brand out there...

any pics?

I will find out in a few days. At least this tube is shipping CONUS. I am still waiting for the GEC. It is going to be Christmas for a while with all the tubes I have coming.
