It's pretty similar to what a lot of other's have already done. Basically just some big film output caps, a Valab 23 step attenuator, and a small bypass film cap on one of the power caps. I also replaced the braided input wire with some shielded Mogami mic cable to reduce interference. I'll post pics tonight when I get a chance.

The Valab or Dale 23 step attenuator have to be one of the most cost effective upgrades for the Crack imo.

 

Early days with the choke and the big 200uf film will take around 100hrs to burn in.

 

I will say with the choke and 200uf capacitor a few things are quiet noticeable straight away. 

 

1 Music has a very black background

2 Bass has tightened up there is more of it and its has some good punch and impact while staying controlled.

3 Music has more weight to it

4 Microphonics caused by say putting a cup down on or tapping the table or the headphone cable brushing against the amp this has improved with some of my more sensitive tubes.

I'll have to look more closely into some of these upgrades.  I like the sound of what you guys are saying.  Interesting about the mic cable.  I've got a  bunch of busted mic cables laying around.  I should use them for something.

I don't know if I posted this already. But I bought a few GE, RCA, and Tung-Sol 6080's. And a pair of RcA Clear Tops. I decided that the best sound is still with my Chatham and stock 12AU7, which is kind of annoying lol. But oh well. The cleartops look moderately cool at least

I see someone has a Bendix 6080WB with solid graphite plates for sale on eBay. A very nice tube.

Would it be wise to pass up the solid and wait for a slotted to turn up?

All graphite 6080WB are wanted. Some prefer the slotted.

Don't swallow tube dogma. Buy and try. If you like them, keep them. If you don't, sell them on. A lot has to do with the other elements in your chain. Tube rolling in the Crack only offers subtle differences.

Here is the link to the Bendix selling thread, just in case someone needs it.

But to be honest, this is not the best price you can get for this tube. I personally had my Bendix Slotted Graphite Plates tube for around 45-55$ ;)

You did well on them those slotted plates the last two pairs I saw on ebay both went for around US $285.00 plus shipping which seems more the norm, The Graphite plates don't come up very often and are getting harder to find.  Let me know if you want to sell one I would be happy to give you what you paid!

Don't get carried away tube rolling. Stop to enjoy the music.

25 years ago (when I had no knowledge about equipment or being an "audiophile") I used to enjoy the music  from my Sony Walkman & bundled HP's as much as I do today from my 15 odd Hp's  + 4 amps + 40+ tubes. Only difference is now I also enjoy my equipment as much as I enjoy my music. ;) 

Music is an undying passion, Equipment is the associated hobby.

Well put. Gear preoccupation is almost and unavoidable association for this hobby. 

post #4785 of 5999

I was just thinking to my self would my passion for music have decreased if I had not discovered "audiophile" equipment  & was still listening to music on an ipod  --- NO.

 

Equipment has not made me love Music more (I love "On the Turning Away" with the same passion whether on the Sony Walkman / Ipod or on the Crack + HD 800) , but Music has made me love equipment more because of the various shades with which it can present music. If you get my drift.
