Have you linked J4 to J5 on the bottom of the pcb, as there isn’t a link on the top?

Hi Kevin,
no I don’t.
Do it after reading your post and now it works.
Good damn.
I thinked about, but also thought, they are just for DI-Use.
Thank you very much !

They are for DI use but if you don't have a DI you need to link them. I am pleased you got it working. My friend Pierre hosts an independent gallery projects that people have completed based on my designs:

If you have any when your build is complete you can send them to me if you wish and I will pass them on to Pierre.

Hi Ian,
I want to use a DI, but I linked the DI to the toogle board to the line molex.
So I hope, I did not something wrong.

The input impedance of the line input is about 7K. This is probably too low for guitars. Normally a DI input wold be fed straight  into J4.

Have you read the documentation about how to set it up for various uses? You can find it on the DIY tab of my web site:

Scroll down and click on the Classic Solo folder where you should find all the info you need.

Yes I read it, but I thought, i can connect the line to my di input jack.
Will try it later, if not, I will connect J4 to my DI input jack.
But for now the preamp work fine and sound great.
Thanks so much for your help !

Finally I’m done!
I learned a lot with this preamp.
Now I’ve a wonderful sounding unit and with the output gain I can drive the tubes harder.
Ian thanks so much for this project !
I am already in love !

Nice pic. OK if I send it to Pierre? Do you have a shot of the inside?
Is that a Galaxy enclosure?

Yes of course!
But I'll send you better pics tomorrow to your mail-address.

Yes it's a Modushop Galaxy enclosure.
The front- and back panel was drilled and printed by Frank.
I used AVD transformer in and Edcor out.
Capi T-Pad for output attentuation and Phillips 6922 JAN tubes.
The rest is standard.

My Mic/Line switch is now a mute switch, cause I first thought, I can use the line switch for my DI.
So I've just one xlr input.
I think about using the same input for the line switch, then I can drop the input gain about -30db.

I'll start to put a pair of these together soon! Has anyone experimented with adding an LED to show when phantom is active?

No experience, but you can use it like in the ez1290 build.
Just connect the plus of the LED to pin 2 and 3 and the minus pin to audio ground.
I would use a something between 5k and 10k as LED resistor connect between XLR pins and the plus pin of the led.
But maybe Ian can chime in and prove me wrong.

Depends what you mean by  active. The usual method is just to connect the LED via a suitable series resistor (10K should work for many LEDs) to the switch that turns on the phantom power so when phantom is  turned on the LED comes on too. I do not recall the total current the Classic Solo power supply can provide  from the phantom supply but I do not expect an extra 5mA would worry it too much.
