Single Rectifier II FX Loop mod - DIY? Walk me through it?

[GibsonV05]

My Boss delay, MXR chorus, and RV-7 reverb really suck in the parallel loop. How easy is the loop mod, and can I do it myself?
The only authorized Boogie repair facility around here gave me B.S. about mods. They "don't do mods, because customers complain, don't like this, that, etc.). I perfectly understand, but I don't even consider it a mod, more of a "fix". I retube and bias all my amps, and have for years, but don't really care to dig around, if you know what I mean.

Mine is a Series II. Sounds like the mod is what I need, and am hoping others will chime in, and walk me through it.

Very simple mod.
