Doug Self Preamp from Linear Audio #5

[batteryman]

OK so not wasting time searching forever. Are there boards available. As a complete kit? Power supply included??
Thanks for help

Carl shipped me the bare pcbs (set of 3) a few days ago and has a few sets left I think. Most parts are in stock at Mouser (apart from the mains transformer) and I think Bourns pots are available which will fit in place of the specified ones.

Farooq,

That looks really nice! With all of that red and green it looks like an early Christmas.

I am really glad that you are enjoying it.

Great to hear of another successful build! I invite you to post some PICs.

Yes, that does look great & glad it sounds as good as it looks. My pcbs have arrived so I will get it built this week.

Hi Carl,
Have hopefully attached photos

Tried again , but there seems to be an error with "security tokens" and I'm not entirely sure what to do next. Ashley

3rd and final attempt to send photos. I'm obviously doing something wrong and too stupid to find it.

Ashley,
Have you tried these instructions posted by member Mooly?
How to attach images to your posts.
Not clear on what Batteryman's post is about...

Don't feel bad Ashley,

Mooly had to personally send me his instructions before I figured it out!

Here you go, nice job Ashley!

 

[brian92fs]

Very nice!

What's the board next to the power supply?

 

[batteryman]

Here you go, nice job Ashley!

Looks great.

I am thinking of building mine into a 3U case so I can also fit my IanCanada's I2S to PCM board and my own dual TDA1541 balanced Dac & I/V transformers with their own power supply. (probably with shielding over them or a horizontal divider)

Here you go, nice job Ashley!

Great job,

What type are these green pots?

 

[chakaandgeorgie]

The green pots are OMEG eco pots. Only 4k7 not 5k, but seem to work well.
The extra pcb is just a primitive power supply to drive the power switch and selector LEDs.
