A while back, I got a bit over achieving, I decided to replace all the caps in my K100C-8 amp, both preamp and power amp sections.
Amp works and sounds fine, but, after a few minutes it produce a loud pop. It does not do this just once, it will repeatedly do it.
Not sure exactly what I did, but probably should take it in to have it looked at. I suppose my question would be, anyone have any rough estimates at how much this could cost me to have diagnosed?
Also does anyone have any recommendations where to take it in the Portland Oregon area?

Agreed... I was thinking about disconnecting both preamp boards first.. Wanted to see if I messed up a cap in the power amp and try to isolate things.
I'll go back and see if I can find the cap I put in backwards. What about the possibility that I put in the wrong value of cap? Would that cause a pop?

Yesterday I took the amp section out of the cabinet and poked around... I think i may have fixed it, but I have to tell you what I modded first.
I have a Boss GT10 guitar processor. I wanted a way to go directly from the processor to the power section of the amp. So, on the top left input, i modded it such that that input jack goes directly to the power section. Also, rather than unsolder what had already been in place, I simply took unscrewed the existing jack, bent it out of the way and put a comletely new jack in it's place.
So, what I think was happening was that the jack that I had unscrewed, and bent it out of the way may have been making contact with the chasis or something. I took it, wrapped it up with electrical tape, plugged it all back in. Not a single pop, nothing. Sounds great and is performing just fine.
Having said that, I'm still going to keep my eye on it.

Hi Steve,
Off the top of my head, I'm not sure. I can check the manual when I get home, but I can tell you that the Boss GT10 seems to provide MORE than enough UMPH. Minimal volume on the GT10 get the Kustom ROCKEN loud! I've never had the volume up past maybe 1/4 of the way, if that.

Hi Pleat
Actually what I did on that channel is to re-wire it so that it completely by passes the preamp all together, I wanted to go directly from the GT10, directly into the power section. So the way it is now, none of the preamp controls do anything when I plug into that jack. All tone and volume is controled on the GT10 itself.
