US made, integrated tube preamp able to handle KT150 tubes?

I do not have his pre-amps, but I have the Elvis and it is excellent.

How often do you have to bias the tubes on a rogue? Manual dexterity (tremors) is not my strength. looks like a fairly simple process 

Quicksiver audio by Mark Sanders from Stockton CA , hand made legendary performance! I own his 60 watt mono and his incredible HP amp 

I have two PL HP’s. On running EL34’s and the other KT120’s No problems with either. 

What speakers? 15O’s could be more than they need. 

The 150’s are hot hot hot! Hot!

I owned a Rogue Stereo 100 Integrated for a minute. It sounded terrible. It didn't match my speakers well at all. Dealer wouldn't take it back, Rogue was no help. I used it for a boat anchor, it worked well.

Keep Rollin.
