The ones with 5 pins are switched jacks.  Read the last section on wikipedia.   http://en.wikipedia.org/wiki/TRS_connector     Basically when you pull the male jack out the L/R will close and the signal will travel to the remaining 2 posts.  You can get either but if you get the 5 or 6...

When measuring my board the 3 marked points I thought were ground did not have continuity to the ground plane.       The board I have is a newer revision than this one.  There are also two more ground points on the one I have which was nice for grounding the pot itself.  I jumpered...

After reading your comment I had one of those head slapping DUH! moments.  The  ε27 board was made for balanced input so the L/R grounds don't connect.  One of my channels was properly grounded and the other was not sweeping to ground.  So after making a little jumper that problem is solved.  I...

I just can't win with this amp lol.  I figured out what the problem was. The ε27 board has 4 pins for in and 4 pins for out.  The outer pins are L and R and the two center pins I assumed were ground.  On the board I have the G is centered between the two middle pins.  Well it turns out at least...

Sorry Cfcubed but I am having another problem.  I went ahead and replaced C4P then cased up my CTH but now it just humming very loudly as in full volume loud.  I ordered a spare c4p so I tried a different cap since that was the only thing that changed but it didn't do any good.  I already threw...

  Thanks guys.  I wish I had access to a drill press.  It would make casing a whole lot easier.  I have a perforated top but the tube hole is just in the wrong spot.  For now I am going to slide the top back to where the tube needs to be and then cut off the back extra with a dremel.  I will...

  Quote: Where did you source your perforated metal from?  I need a new top for mine and that looks pretty cool.

IT LIVES!  Thanks so much for your help cfcubed.  To no ones surprise it was builder error.  C4P was backwards.  After switching it and then double checking every other cap on the board and going through all the setup tests again it fired up just fine.  My input leads are way too long and...

That diagram is perfect.  I will get those measurements taken.  Do you know what q1p is suppose to be?  The discrepancy between the bom and the color diagram has me concerned.  I will start checking the other parts in the green box.

Ok ICP center to IR = 0v  ICP center to OL didnt measure.  What I mean by that is when I measured IR my multi-meter read 0v but when I measure OL it kept bouncing around in the mv which is what it does when there is no continuity.   TB-SG was 110v   "low-voltage heater (measure across...

  Thanks for helping CF.  I am at work right now but I will take those measurements as soon as I get home. (I should have refreshed by browser before replying I wrote all of this without seeing your second post.  I will get all the data tonight.)   1) I did look for bridges but I will...

I need some help guys.  I finally got my CTH all populated and wired up but  I am having a problem.  No smoke and the LED light turns on but SG-OG is 1.3 VDC and SG-OL and SG-OR is 0.  I have no idea what to do.  I built this using a kit from Waitrob I got almost 2 years ago which I should have...

I am almost done with my original CTH. It has been shelved for almost 2 years due to moving and a new baby. I was hoping someone had an idea for a replacement multi colored LED for under the tube. I am red/green color blind so the provided one wont work. I haven't been able to find a red/blue...

LoL ok this is my last post on this matter. I seriously laughed for a good 10 seconds while reading this post. Quote: Originally Posted by skyline889 there was no brand. Thanks for answering my question. Quote: Originally Posted by skyline889 People like you who...

Ok, so when is the NEXT Iowa/Nebraska meet? I didn't have my location setup in CP because I am lazy like that and it looks like it cost me dearly. I just saw LingLing1337's signature today and am very jealous I will be missing out. I hope it goes well and you decide to do another one. In fact I...

LOL Well I guess I will make sure to subscribe to my own threads from now on. I assumed this was a dead topic and I miss out on basically free solder I ordered 1lb of kester silver bearing since it was such a great deal and I plan on ordering a small amount (50ft) of Cardas quad this week...

Thanks everyone for all your input. I will be getting the Cardas quad and the Kester.

I decided to pick up some premium solder for my pending CTH build so I went over to the bay to see what was available. My intention was to just pick up the Cardas because I assumed it would be cheaper. My assumption was wrong. After shipping WBT and Cardas Quad cost the same (within $1 anyway)...

The title says it all I have been looking for a high quality 4 conductor jack so I can make my own cable for my zune dock. I guess the alternate question is what happens if I just use a 3 conductor? I don't care about the video but I don't know what would happen if I just ground it.
