Help!!!! I'm a newbie who should have listened to you experienced Bottleheads and build stock first and then add upgrades. But nooooooo...I had to build from gitgo with sweet whispers and anticipation upgrade. Good news is that resistance checked out OK and when plugged in the tubes glow, no smoke,sparks or fireworks. Bad new is that voltage readings are really out of whack. Only LED #D2 glows on each of the C4S boards. Should both LED's on each board glow?
What do you think...have I fried some parts or put something in backwards???????

It looks like the C4S modules are not providing current to the tubes, so there is something wrong with them. Yes, both LEDs should glow on each module.First check - are you using the magnet wire to install the C4S boards? If so, there may be a poor connection if the insulation is not burned off completely.
You might consider removing the C4S boards and returning to the stock configuration - that way you'll have sounds, which is rewarding and encouraging. Then you can go over each C4S carefully and liesurely while you have some tunes. First, check that each resistor is the right value - it's easy to miss-read the color code, they are pretty small. The make sure the LEDs are installed in the correct direction. Then the transistors. Post if you find any errors, and we'll help figure out if any parts have been damaged or not.
Paul, thanks for the tip...you were absolutely right. i just got through removing the C4S boards and putting in the stock resistors. The readings for the terminals that were previously not getting any voltage are now getting a decent reading. Do you think the high readings I'm getting at most terminals will be a problem? Can I proceed to the next step of hooking up to amp and speakers? Despite all my dumb mistakes and several asperins for headaches I got from trying to figure out what I've done wrong this have been a fun project. The workmanship on my unit sure is UGLY compared to the work of art that Quest has posted on his site. This site has been great help. Thanks to you experienced Bottleheads for helping me get closer to bringing another Foreplay into the world!
