Buddy is the monster of our power amp lineup, a 120W mono block - quite the performer! As the  'mono block' description infers, two Buddy MKII's are required for stereo and the price does reflect 2 mono blocks.
 
Buddy is built around a quad set of KT120's beam tetrodes in a parallel push-pull configuration with a preamp/driver section consisting of two Tung Sol 6SN7's.
 
An Auto Bias circuit, identical to the one used in our model Elvis MKII 60W/CH stereo power amp, takes the guess work out of keeping the bias for the big KT120's at the correct level. We set the bias, then you'll never have to worry about adjusting the bias again!
Please contact us if you wish to know more about the Auto Bias circuit and how it works.
The 120W of tube power will require a set of speakers that will not flinch when these mono blocks get going!
 
Nothing but the highest quality transformers are used throughout. The OPT's are the excellent Lundahl LL3723/PP and the power transformer is our design and custom made for us by Heyboer Transformers.
 
Inputs can be supplied as optional XLR using the excellent Lundahl LL1544A audio transformer.
 
These amps are build to order and will take 6-8 weeks to complete and ship.
 
Every pair of Buddy mono blocks comes with your choice of chassis wood and plate colors.
