Chris doesn't like rabbit holes. :D

 

He gave up on vinyl pretty quickly (rabbit hole), and doesn't tube roll (rabbit hole).

I should also mention that we had a really big Cavalli presence at the Austin head-fi meet.  We had two LG's, 1 LF, 1 LL v1, and 1 LL v2.  It seemed like lots of people got some good head time with the LG's.

 

You would need to ask Alex the details.  I am unsure exactly what he did. 

 

For me, the LG the right light always switches to red randomly in pre amp mode.  The output Safety turned on.  I tried it with all my amps.  It always seemed to happen.  It could happy for like 1hr or happen 3 times in 20 mins.  I dont know what would cause it.  

 

Alex said he has a mod for that and it should fix it.  Now I havent had any problems with my power amps.  I did it once for some reason but hasnt happen again in a few days.  I am happy with my LG. Sounds great with my headphones and now I can roll tubes with my speakers too.  

 

 

I have a question about the RCA coin base 6sn7.  Does this count the 6SN7GTB? or if you have a link to a decently priced one :D

Mine did the random red light too but in headphone mode. Then I saw I left two phones plugged in. one in 4pin and 1/4". Both orthos. After a few days of troubleshooting, cables, dac, drivers for windows and tubes, I noticed the LG was driving both headohones same time. Guess the load was too much it went to protected mode and thus the red light. Now with only one phone the LG never switch to red light anymore. Anyone know the maximum output for the LG? Driving two dynamic phones like 3000anv and DT48 no problem at all.

From the Cavalli Web page :

 

 

More Details:

  • The SS buffer will provide about 6W into 50R

 

 

..dB

 

was this with the BL65 tube too? - this tube probably puts more strain on the plate power supply too. It shouldn't pull it out of regulation but if it does, the offset will trip .

Is that 6W in Class A or AB?

Thanks!

Alex told me while back that its like 150mw or was it 250mw of class A and rest AB
post #397 of 624
Found the email Alex sent me.

Class A or AB depends on how much current the headphones need, with the lower impedance headphones like LCDs or HE60s needing much more current than HD800.

The output bias current in the LG buffer is close to 150mA. This is very high for a headphone amp and will keep the LG in class A mode for much of the time. But, it effortlessly slides into AB as needed. The tube stage itself is always in class A mode.

Guys,

 

There are still a few more LG's left. Once they sell out, that's it. The LG made a splash at the Austin meet here last weekend - it's really gained some great exposure. If you are thinking about picking one up, I'd encourage you to act soon. Especially if you've got the tube-rollin' bug! We want to make sure our Head-fi guys are taken care of. It's a great deal for a really nice amp. And that black faceplate option looks so nice! See the site for more info.

I've been meaning to take some photos of my LG for a while now, but never quite had the chance. Pardon the crappy photos, but I didn't have time to properly set up the shot nor to post process.

Stealthy. Very stealthy.

Fantastic photos there, mwilson. You captured that stately, stealthy look perfectly. What a beauty.

Agreed, very excited to get my hands on my own. That thing looks like something straight out of The Bat Cave ph34r.gif

Beautiful pics. What do you shoot with, mwilson?

Mostly with my Beretta M9, but there are some occasions when I grab my M4 carbine
