  So, Ive been wondering, how hot do y'all's Lyrs run?  I know that they're supposed to use the case as a heatsink, but after about 40 minutes, mine becomes hot enough that I can't touch the volume knob for more than about two seconds before it is too hot to handle (literally and figuratively).  Is this normal?

My Lyr 2 never gets that hot. At its hottest, I can rest my hand on the case. In fact, on cold days, I would often do just that!! My Mjolnir 2 is about the same. If anything, it runs a little cooler than the Lyr 2.

One day, some kind member from this thread will pm me and say, "you know Matt, you're a good guy and I'm gonna give you a good deal on a matched set of PW."  One day...

Don't takes this personally....

That was pretty funny.

 And then, I got a pm...

I have read similar comments from other Lyr 2 owners, but mine does not get too hot to rest my hand on it, even when I leave it on all weekend. And the volume knob could best be described as "warm."

I'm not sure if the running temps really vary that much, or if other owners are just being weenies.

The lyr2 can get very hot where the volume knob is too hot to touch for very long. It depends on the room temperature, how much ventilation there is around the amp, how long it's been on etc. This is normal behavior for this amp.

Is a 6cc42 tube compatible with an adapter?

  Is a 6cc42 tube compatible with an adapter?

 
Yep, I was just running a pair of Western Electric 396As (equivalent to 6CC42 / 2C521 / 5670 / Russian 6N3P).  Got the adapters off eBay for about $16.  According to the specs
 
http://www.radiomuseum.org/tubes/tube_2c51.html
 
it should be fine in the Lyr 2 / MJ2, but as I don't own either and am not an electrical engineer, you should confirm that with someone who knows for sure.
 
FWIW, I love those WE 396As in my Lyr, more so than the 6CC42s I've tried, which aren't bad.  The 5670s can be had for next to nothing, and are a fine alternative.  You'll pay more for, say, the GE 5 Star version, but they're probably worth it.  My pair is quite nice.
