Solen SUB-250R bass boost

[Jonnyc]

Hey all!

I have a Solen SUB-250R plate amp. I realize that this is an old amplifier, but I was hoping someone would be able to tell me how to remover the bass boost from it? I know that it's an easy mod, but I'm just not sure what that mod is. If anyone could point me in the right direction, it'd be greatly apreciated.

Thanks a lot,
Jon

Here are the bass boost removal instructions. I can email the subsonic filter removal instructions if you like, the file was to big to attach here..
