Has anyone noticed a significant difference in sound with different solder being used? I imagine no but I'm sure we've all been surprised before.
Nope, dont waste money on that stuff. Just get good quality solder from a company like Kester, MGChemicals , etc

Have you guys noticed differences between the different 6080? I personally liked couple of 6080 tubes I've tried, and wondering if there are differences in sound between the different 6080 tubes.

What is yall's top sounding tubes?

I've rolled a lot of tubes through my Crack(atwoa).

There are differences between the 6080's, but they are more subtle then going from a 6080 to something like, say, a 5998.

IMO, the two best 6080's I have heard are the Mullard CV2984 and the Tung Sol 6080 (not to be confused with the Chatham rebrand or other rebrands)

In terms of the BEST output tubes in the Crack, here is what I have at the top of my list:

Tung Sol 7802 = Western Electric 421A > Tung Sol 421A > Tung Sol 5998 > Mullard CV2984 = Tung Sol 6080 > everything else I have (Tung Sol 6AS7G, Bendix 6080WB, Chatham 6080WB, Sylvania 6080WC...that might be it)

Granted, I haven't listened to a lot of the tubes on the bottom of that list in quite a while.

Basically, yes. Mine has the JAN-CTL-6080 designation. 62-16. I'm assuming that's a date code? Year and week of year? 1962, 16th week?

Neither of the above tubes is a "true" Tung Sol 6080, the one on the left is a Chatham rebrand. Not sure of the right, but I suspect other rebrand.

The Tung Sol 6080 has silver support rods and should have the "322" Tung Sol factory code, see below.

Sounds like a Crack(atwoa) is quite different than a regular Crack. :)

The Bendix 6080WB sounds great on a Crack.

But everyone has their own tastes and preferences.

Nah, the same rules apply, just a matter of preference. I've tried several times to find the appeal in the Bendix, especially since I paid a pretty penny for it. I think I haven't been able to get over how collapsed the soundstage feels compared to something like the WE 421A or TS 7802.

Maybe I need to reevaluate my priorities and give it another try :dt880smile:

TBH, the Crack don't deserve any tube cost more than $60. So a couple of 6bl7/bx7 is your best bet. I used to love those tubes like crazy.

I wonder if they can design an amp identical sound characteristic of the Crack, but with much greater power and works well for low impedance headphones as well? I do like how the amp images for the Sennheiser HD6 series (so interesting how the headphone images out of this). If I can get same imaging push for other cans of low impedance, it would be an interesting amp.

It just seems to have very good separation to sounds, outputting distinction in sounds for imaging. Good bass impact as well. Surprises me how fast this tube amp is.

I'm wondering if the result is just pure luck from it's OTL output and HD6 series?!

You can try to ask Doc. B. if he can make you one.

Firing up a Crack with Speedball for my first even listen to this product! Tube wise I've got a Psvanne 12au7 on output and... a French 6080a [Thomson CFS??]? There's two Jan Phillips that came with it but I can figure out what's different about each
