Cavalli Compact Tube Hybrid (CTH) Tube & Tweak thread. - Page 46

post #676 of 680

So the verdict is, as I feared, kaput.  Once I get a new amp, I'll see if anyone around here is interested in my CTH innards.  Poor little guy.  frown.gif

Sorry for kicking a somewhat dead thread but I had a question and thought it might be better to ask here than start a new one.

 

I have a small guitar practice amp that I'm very happy with except that it doesn't have a headphone jack for late night practicing.  It does however have a preamp out.  Can I run the preamp out of the guitar amp into the input of the CTH?  It would require the proper cable, e.g., 1/4" to RCA or 1/8" (I have both inputs on my amp).

If you start with the volume all the way down when you try I don't see that harm could happen. 

When the volume is all the way down the CTH's input is swept to ground (it doesn't "see" any input).

And the onboard e12 should trip if anything goes wrong. 

IOW I'd give it a whirl, granted its lower risk for me because I'm a builder:)

 

Edits:

* If its a mono amp then the preamp out is likely mono too.  In which case your adapter(s) would need to link the preamp's single channel "+" to both the CTH's L & R "+"s (to hear sound in both earpieces).

* With Joe Audio now offering CTH PCBs & kits ( http://joeaudiophile.com/shop/ ) the thread could see some posts. Tho most topics are already covered.

And you're the builder of my amp also.  If the amp fails I'm going to track you down and try to get you to fix it.  :)

I've been using the CTH with an Amperex Bugle Boy ECC82 to drive Audeze LCD-2s. The bugle boy has given me the most extended treble, from among Mullard, Telefunken and older Amperex tubes. Does anyone know of another tube that's even more extended in the treble, to balance out the LCd-2?

 

Also, has anyone heard both the CTH and the Schiit Lyr and compared the sound quality?
