Modding the LPB-1
Posted: Fri Aug 14, 2009 1:32 pm
Since my cc/dc has replaced my LPB-1, and knowing that it won't go for much on the used market, and always wanting a "treble booster." I figured I could mod my LPB-1 to screaming bird specs. Has anyone else done this?
I looked up some info, and found that I need to replace the 2 0.1uF capacitors with 0.002uF capacitors. I open it up and there's 3 and they are all the same value, but also read that I need to change the caps that interact with the transistor, so I'm assuming, in this case the two right beside the transistor are the ones that need changing. Doing a quick search for parts leads me to finding only 0.0022uF caps, are those the same things? Also is important what kind of cap I get (electrolyte, film, ceramic.) They look like film caps, should I replace them with film caps?
And my final question, how hard would it be to wire this to a 2 way switch, that would allow me to switch between the 2 values?
I guess these would help some?
