Dynaco M-125 MONOBLOCK + AB ultimate upgrade kit, auto bias for CCS driver VTA

I offer latest upgrade kit, for MK-125 Monoblock. This kit will replace the original Dynaco driver circuit and printed circuit board, fitted 12AU7 triode. Tubes are not included with the kit!

This set will give your amplifier a revolutionary look and great sound!

The kit will consist of all the necessary parts to assemble and install the new driver printed circuit board, and of course the AB-Q-M-125 Auto Bias module. 

The boards driver M125 and AB-Q-M-125 auto bias is pre assembled.

Kit contains:

- Russian oil capacitors and other name brand capacitors

- quality metal film resistors

- ceramic pcb mount sockets

-  necessary hardware to install the printed circuit to the amp chassis

-  fully assembled model AB-Q-M125 auto bias module

-  fully assembled model driver M-125

NOTE: all the parts are loosely packed in resealable bag. They are not packed into individually sorted parts.

The benefits of upgrading your Dynaco M-125 amp with our are:

1) a modern tube circuit using a LM334 based constant current source for a stable circuit

2)with the auto bias, there no more having to keep an eye on the output tube bias setting. The auto bias module will keep the pre-set bias for the life of the power tube! The bias level is pre-set by us to suit the EL34 (6L6, KT88) family of tubes.

3) not to mention that your M-125 amp will look pretty cool with with blue LEDs that shine !

No matter the age of the tubes the auto bias module will maintain each tubes' bias level at the preset level! So the output stage is always well balanced and held in equal bias!

This kit requires assembly and soldering. Please make sure you understand what you are buying because I do not accept any requests to return the kit.
