I tried it and the constuction is very light and not inspiring. Although the sound is smooth and reminescent of the Tungsol 6SJ7G. Though I got one defective that nearly burned my amp... So I never use them again and sent them back to the seller.

So, one of the RCA 6AS7 stopped working.  It wouldn't light up.  I let them cool down, turned off the amp and then swapped them.  It was the tube.  I have sent the store an email asking if I can return the tube for another one.  If not, I am might as well invest in some 5998s and be done with it. 
 
I have read the 'JAN' stands Joint army and navy.  I have seen some JAN 5998 and I am wondering, are these a little different to the regular 5998? In terms of sound quality?
 
Any other substitutes for the 5998 in terms of the extra power and sound quality? I am using HE500 btw.

mine say jan 5998 as well, i believe JAN tubes where the same as the regular, though built a bit better and are slightly more durable, but im not sure.
 
should be the same as any other 5998 though.

2399 basically are 5998. JAN tubes are supposed to be the better scoring ones as the navy standard was high.
Don't forget that even when you buy a 150$ 60 year old 5998 tube it can pop after one day, I doubt the seller will refund you.
That's the tricky part about tubes

Thanks for the replies.  Whats a reasonable price for a matched pair of 5998? I almost missed out on a pair on ebay that went for $130.  I am looking at the ones going for $188 and I think that's a bit steep.

I did a 20 piece group buy last month, you just missed it. Prices keep going up quickly. A good non matched pair of NOS 5998 lately starts at $150. Matched would be more unless you get lucky. Occasionally there are good deals on ebay, but are you really getting what they're saying...

Hi all,
 
Transfer back from my hifi dac ( calyx ) to my headfi system ( using the odac ).
 
 
Anyone encounter this problem?
 
I'm using a odac+o2 combo. Amplification part unused hence now the dac is only powered by the usb.
 
I'm plugging it to a tube amp , 3.5mm out to 2x RCA.
 
The gain seems to be too high and causes distortion. I'm currently using foobar ( with wasapi ) with volume reduced to -12db and it's better. 
 
Is it meant to work this way?
 
Thanks

I know I am kinda hijacking this thread with my little issues, hehe, but I have to mention this, I just email the seller of the RCA tubes about the bad tube and he offered a refund or a replacement.  The website is www.electols.com and I have been in touch with Michel.  Now, that's really fantastic customer service. A bit hard to come by these days.  They have a great selection of tubes, always worth a look. 
 
Ultrainferno, yes I just missed the group buy.  Please keep me updated on future group buys of tubes, scotch, cigars...  I would be very interested. 
 
 
 
 Occasionally there are good deals on ebay, but are you really getting what they're saying...

 
 
Sometimes yes and sometimes no.  I guess it's luck of the draw.  I do rely on paypal as backup. Never had any issues so far and I have requested a couple of refunds which have worked out but I know for some people this has not been the case.

As i already stated..try the bendix 6080wb with graphite columns..also high gain tubes.and perfect for he500...almost same sounding as 5998 ts...but to my ears stronger bass and bit less detail compared to the 5998..i have both..

I got my matched pair for 220 usd.

Thanks mate, I did read that before, but they do go for around $40-$60 each.  I might as well put in a little extra and pick up the 5998.  5998+5693/mesh plates+He500=Nirvana... 
 
Sorry back to the topic guys.
