Help noob maintaining anmodding Plexi w/ London Power

Post by Tito83 » Sun Jan 25, 2015 10:42 pm

Hey! My name is Victor, I'm from Brasil and this is my first post here! First I want to say thank you for reading this and that I do know I'm I'm asking isn't the easiest thing in the world, but I have really nowhere else I think I can ask for help with this.

I have this amp built by a builder that isn't in the business anymore, where I live nobody will touch this, so before I have to pack and ship this thing, I have a few things I wanted to ask:

How is the biasing done in this amp? I've done this to other amps, but I don't know if the London Power thing changes anything or what.

What does the dual pot thing does? It's a control called limit, does affect the overall gain and volume of the amp, but I always wanted to know what it actually does and if there's any setting that would give the "stock" plexi thing.

The third I guess it's the hard one, it's about mods. I've done a few pedal mods, I do ok with a soldering iron, but I have no clue of what I'm actually doing, I just follow instructions. Is there any mod I could do to the amp? Don't get me wrong, the amp sounds fine as is, but it's not "that" sound for me yet. I read about the cascate/one wire mod, always wanted to try it, but my amp layout looks a bit different and I'm not really sure how to do it from pictures. Any other mods to give a little more oomph would be appreciated. Besides, if any of you guys see anything I could do to improve the amp somewhat, some tips or wherever, I'm all ears.

Here are the pics, if anymore are needed/wanted, just ask!

Again, I know I ask a bit too much, but any help would be greatly appreciated.

Cheers
