Tube Driver help?

[jasonober]

so I'm building the tube driver from GGG
http://www.generalguitargadgets.com/diagrams/tube_driver_sc.gif

It's all pot together but not working maybe someone can help point me forward.  The only thing I've done different is use .22uf in place of .47uf at C10 & C11 for now because I made the mistake of ordering electrolytics rather than film and didn't know which way to orientate them. So, using audio probe I lose signal at IC.  When measuring voltage I read 13.9 at + input. My IC readings are:

1.  5.90
2.  5.87
3.    .27
4.   .70
5.   0
6.   3.76
7.    5.67
8.     6.39


I've gone over circuit to check soldering and cap/diode orientation and everything seems to be per schematic.  Any suggestions?

[jasonober]

maybe this is more help
1st     I'm using DC jack with 12v 500ma wall wart



Tube readings:
1.    6.2
2.     .52
3.     .73
4.    13.03
5.        0
6.     2.64
7.     .65
8.    .73

I think this is your problem - the power supply taps the AC wave for cheap bipolar power.  If you use a DC adapter, you can't do this.

Unless you ment AC Wall-wart, then nm.

[jasonober]

well i don't know   here is the adapter

do i have to build power supply with transformer?

[Hal]

yea, thats not gunna work.

Yes, you need to build their power supply. If you don't want to wire mains, you can use something like this...

or less weird but more money, and overkill current,

How 'bout this?

[Hal]

yup, should be good.

Do you have the rest of the power supply built?

When you _do_ do this, make sure you differentiate between -v and ground.  They're not the same!  This has a bipolar power supply - It will have V+ at around 15v, V- and about -15V, and ground at 0.

[jasonober]

thanks for now    i'm going to replace my power supply and then i'll see what happens

[jasonober]

works great   thanks Hal   :D   Sounds better to me with 082 instead of 4558   thanks again

[Hal]

sweet, I was hoping it was that, and I wasn't being an idiot :-D

You really like it?  Not too hard to build, right...I'm thinking of doing one of these...

how much did parts cost you?
