    Well this is interesting. Bias is 0.005v on the affected channel. 0.368v on the good side.

    Yeah, I have +15.06 and -15.42 on the affected side.

    I have three other control board kits... Part of me just wants to build another control board and swap it. I need to build them anyway.

    So, I checked all 7 glass fuses - two on the right channel backplane, two on the left, and all three supply fuses and they are all good. I checked the nuts on the DCP board and those are tight.

    It definitely sounds like a loose/dirty/scratchy connection. Like a scratchy potentiometer.

    I will say, the last time I used it was a party where I went to bed and there were still people there playing the music at extreme volume. It's very possible that something popped after I went upstairs and nobody said anything about it. I'm stuck at work until 5. I can check all fuses when I...

    I was thinking that a blown fuse would result in no sound or very quiet sound. Is that a false assumption? Are you talking about the glass fuses or like a pico fuse?

    Good question. It's a full comp WOPL build with a PL14_20 RevG1 Dual Mono Control Board and the RevC blackplane. Ideally I would like some recommendations on where to start looking. I went over it with a magnifier looking for cracked solder joints or sloppy work since I built it myself, but...

    Help! I have a problem with my 400! I haven't used it in a few weeks. I powered her on today, and the right channel is extremely distorted. It sounded like a blown speaker. Left channel is fine. First I swapped the speaker cable output to rule out the speaker, and the problem moved to the other...

    Hey! I disappear for a year and come back and Gene is the one giving advice now! That's awesome. I have still not started my WOPL 700... Too many other projects in queue and I've been too satisfied with the 400 to get the upgrade itch yet. I saw one of Perry's 700s2 builds on eBay and it...

    I drank more sazerak and Bourbon Old Fashioned's then anything else mixed in with quite a few beers. I did have a hurricane with breakfast though. Flying back home to Chicago now. Had some good oysters and gumbo. Some crawfish. A few po boys. No beignets this time around. I came back in 2018...

    Gene, I meant to tell you... I've been in New Orleans all week. Stayed right on Bourbon St. Spent more time on Frenchman though.

    I have one of Joe's replacement chassis for a 700, but I'm not sure which one I'm going to use it on. One of them had a torn ear from rack mounting... That one either has a new chassis or an ebay posting in its future. What is the general consensus - for my first 700b build, is it easier to...

    He wasn't happy... Came off the stage, dropped off the guitar and went to the bathroom crying. It wasn't that bad, but he's a perfectionist. He hasn't come out yet.

    Missing SRV is my biggest musical regret. He's one of my all time favorite guitarists to listen to.

    My son has a school of rock show today... He's playing Blue Bossa. I'll post the link if anyone's bored and interested in hearing a talented lil 12 year old play jazz guitar.

    I saw Joe Bonamassa for the first time in 2005 at a small blues club in St Charles, IL. The place probably only holds 2,000 people. It was the night that Joe met Kevin Shirley. It was one of the most amazing live music experiences of my life.

    I have a bottle of Pappy's for special occasions, but my go-to is Russell's Reserve 10 year. It's delicious and can usually be found for around $30. Small batch Four Roses is a good sipper too.

    Sadly, it wasn't me... I haven't seen one under $400 since I started tracking them two years ago. Even the super busted ones that look like they were dragged behind a truck are getting $400.
