Cavalli Compact Tube Hybrid (CTH) Tube & Tweak thread. - Page 13

post #181 of 680
Hope it's not against to rules to post this here, is anyone here interested in trading some tubes for the CTH? I have some pairs of 6922/6DJ8 tubes for my X-Can v8 that I don't use (settled on a pair of Sylvanias). So looking to trade one and keep one for the CTH, have JAN Phillips (marked in green print), Westinghouse, Siemens (currently using one of thse and its really nice). If anyone is interested please shoot me a PM, looking to taste some different brands. Might be interested for trading a few for one nice tube or just one for one.

But I'm really enjoying the bass on the Amprex tubes. Listening to Pavement right now, and the bass extension is amazing. Going to spin Real Emotional Trash next and see what Joanna Bolme's bass sounds like. Can't wait to try these out in the Bijou.
I think your observations are spot-on WRT 6dj8, so I guess add a CBS/Hytron 7730 to my search list... You've mentioned that tube quite a bit as a fav in the CTH.

6GU7 anyone? Just showed up at my desk, more soon...
post #184 of 680
imho, one of the best tubes i have dropped into the "other" amp ..dB
post #185 of 680
I am liking it very much, clear, excellent staging, generous but not bloomy bass (hey, tubegeek terms!) and cheep (relatively)...

Perhaps we might form a tier system for tubes - Tier 1 beginner/cheep Tier 2 intermediate/ affordable(?) Tier 3 Spendy/the best!

Oh, drat, individual taste might spoil that...nevermind

heh, my fave tube cost all of about $2
post #187 of 680
my tube of choice only cost $15.

Amperex PQ 8416, best all rounder IMHO.

Sounds good, just ordered a couple to try, couldn't resist.

I think I have now spent more on ordering tubes than on building the amp!

The tube I was talking about is the 6n6p. Millions of them on ebay for cheap. I got mine from Lithuania and they usually come in batches of 4-10 tubes per order. I got 6 for about $14
post #191 of 680
yea 6n6p sound great, Im wondering if the 6h30-dr would be more of an improvement on the 6n6p.

Yes & merci beaucoup smeggy... Listening to the 6n6p now & can say it does sound good. Need to let it warm up & listen & compare more, but it WILL be a keeper for sure.
And thanks to comments here I've a Amperex PQ 8416 on the way too. Someday I need to pare down these tubes tho

BTW we are working a bit in the background trying to come up with a (somewhat) complete list of tubes compatible (& good sounding) in this amp. I hinted about this elsewhere but we may find more tubes coming into the fold then then originally considered.

Has anyone tried Auricaps in the CTH?

...It looks like the 0.22uF could be tombstoned in the small bom case, though the ridiculous 18awg wire would be annoying as always.

EDIT: Now someone has





Initial impressions are very positive, but I am listening to Live-Evil which always sounds awesome. I will have to take some time to compare this with my otherwise identical CTH with Sonicap Gen II coupling caps.

Nice! Would like to hear what you think. And they look to fit in BoM case too

Listening to an NOS one of these now & they are quite nice. Good bass slam/attack while preserving good detail & ever so slightly rolled top-end - all good things & all IMHO of course. Now the only ones on my "someday" search list are Siemens CCa & CBS 7730 but no rush on those for sure...
Edit: But of my tubes, Siemens E82CC/12AU7 is still my "detail king" revealing things in the music I've not noticed before. Mine happens to be the fancy-pants "chrome plate" ver. Might have to snag that Siemens Triple Mica 5814A tho.

Tube rolling is really something for sure & as mentioned elsewhere we may have even more options for this amp, for the tweakers anyway.

So someday I need to thin my tube herd & put some in FS forum <<< Edit: Well not really thinning since I still buying them

Oh yeah those Siemens CCa, or Telefunken CCa. Or maybe them E288CC, they don't have this good reputation, but still a maybe.
Currently installing Mundorf Silver/Gold, because of a stupid mistake I made I got stuck with them, wanted the Silver/Oil ones! Stupid me.
