Elvis

Elvis MKII is a push-pull power amplifier, inspired by the classic Mullard amplifier circuit of the 50's, rated at 60W/CH using a quad set of Gold Lion KT88 beam tetrodes.

The amp uses an Auto Bias circuit, identical to the one used in our model Buddy 120W mono blocks. This takes the guess work out of keeping the bias for the KT88'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 preamp/driver section uses three factory new Tung Sol 6SN7 triodes.

The OPT's are the excellent Lundahl LL3723PP, the power transformer is our own design, custom made for us by Heyboer Transformers.

Inputs can be supplied as true balanced XLR, using the excellent Lundahl LL1544A audio transformer.

Elvis MKII is build to order and will take around 6-8 weeks to build and ship.

Every Elvis MKII comes with your choice of chassis wood and plate colors
