Help w/ Tube Driver

[Paul Marossy]

Oh yeah. I forgot about the choke part.  :oops:

And it is very true that the layout is important. Sometimes a signal path will pick up a hum from another part of the circuit. I always tightly twist my heating filament leads and keep them close to the chassis and as far away from everything else as I can get.

well, so far I tried everything....so now I am going to copy the original PCB trace for trace part for part.

I've looked at it so many times now, this should only take a minute.

I believe I will even wire the bypass  switching up the same way.

Reminds me of my first Shaka Tube build.  

Hope you get it working the way you want it to the next time around. You might want to ask the forumites here if they have built this one. I seem to remember reading that the Tube Driver thing at GGG had some problems...

[Jason D]

I believe the problem is in the layout, mine or the GGG one.
So I am in the process of copying the real thing.

Let you know how is goes.

The results are in ----- the problem was my layout!

I now I have an exact copy of an original Tube Driver. Actually I didn't have another 2200uF, which is what the original used, along with a pair of 220uF and a 470uF. I used a 1000uF and three 470uF caps. It didn't seem to mind.

Anyway, right now I am very happy (and tired).   :lol:
