Zero-loss FX - Marshall 2205 (1989)

[bigjav]

Hello folks:

I just registered and this is my first post here. I have been reading a lot about this Fx loop kit. Unfortunately, I wasn´t able to find any info about how to install it on my 2205 (1989 model). This is the reason to register: I am asking for your help on how to install it on my amp, please?

I understand there is a problem to put it in a way to serve equally well both channels, is that true? Is it completely impossible?
If yes, then I wouldn´t mind to install it only for my Boost (Lead) channel.

This is the schem of my 2205 - http://www.drtube.com/schematics/marshall/2205prem.gif" onclick="window.open(this.href);return false;

Any help and instructions will be highly appreciated.

Thank you in advance for your time and willingness to help!
