Build Reports / Aion L5 preamp build (Long overdue)
« on: December 28, 2018, 08:08:56 PM »
Hey all,

Sorry this took so long. The move and getting set up took a lot longer than I thought.

Learned a ton. To slow down and take my time, how to modify pots to obtain different values, a little about SMD's, capacitors and ripple, managing a messload of pots at one time, etc.

Big shout out to tcpoint for all of his help with parts and questions. To others as well for my usual abundance of questions.

Build materials: Xicon 1% MFR, Mainly 5% WIMA caps with a few 5%TDK/Epcos scattered in and a lone 5% Kemet. Nichicon Fine Gold electros in the signal path and other Nichicon in the power supply. TDK 5% (C0G) MLCC's. Gold plated pin/socket IC sockets. Mainly TI IC's. Mostly Alpha pots and  Bourns trims. Kobiconn power jack an switchcraft g enclosed guitar jacks.

What's missing": The name plate. I will have to find or make one.

Next up: Either the Uber tuber or Rabbit Hole, I haven't decided yet.

Thanks again for all your help.


How Do I? Beginner's Paradise. / Another combining circuits question.
« on: December 16, 2018, 10:19:21 AM »

iíve Searched and could not find a satisfactory answer.

My amp is on the fritz and so last night I started a project that Iíve been thinking about for awhile.

I have a v6 drive from GuitarPCB (vox/fender tone in a box) and a small 20w stereo class D amp from Adafruit that I was thinking of combining into one enclosure.

Is it really as simple as routing the output of the v6 into the amp?

Then is there something I need to do to isolate the two power supplies from one another?

Then last question, should I make both circuits common ground to eliminate ground loops or just do that for each individual circuit.

Thanks in advance for any help and If I am way off in left field donít hold back, I can use any constructive criticism I can get.

Open Discussion / Any experience/caveats with Ali-Baba
« on: October 26, 2018, 09:47:35 PM »
So, I still canít source the 2/2.5ka 16mm pots that I need. Am desperate and looking over at Ali-Baba.

Is this a bad idea or does anyone have some caveats?


How Do I? Beginner's Paradise. / Aion L5 Build progress and questions
« on: October 23, 2018, 11:29:29 PM »
OK so I decided Iím going to blog this build as I go.

I only made it to step three before I got stumped. Help me identify this part, I have it my resister box and itís labeled four. 7 AM it reads four. 7 AM on the multimeter I just need to know if itís a different wattage or is it just a different brand than Iím used to her usually use Xicon. I donít want to get done with this and find out that I messed it up in the very beginning

Any Ideas?

Open Discussion / Vote for my next project!
« on: October 21, 2018, 10:54:55 PM »
OK, here are the ground rules. I havenít gone over the BOM for the Beast build. I know Iíve got a lot of it but I may have to trade someone for a few parts. I was going to give an entire week for a vote but Iíve got to get packing pretty soon so why donít we give this till Wednesday at 8 PM Pacific time.

1. Our own, ďRabbit HoleĒ. For some reason I just havenít gotten around to building in 1590A or Iíve been avoiding it subconsciously. Ok, iíve Gone over the BOM and all Iím missing are the pots. If it wins  then I will need to beg, borrow, steal ,buy or trade for these.

2. Once again, our own ďUber tuberĒ. Just donít know much about it although, it seems it involves a number of things Iíve never done. Iíve gone over the BOM for this one and iím Missing: 100 pf Silver Mica, 220uf Electro and then I would also need all of the pots.

3. The Beast Build. Aion Electronics L5 preamp. Iím still Looking over the BOM.

Feel free to include your reasoning.

Get out the vote!

Open Discussion / I think I have a problem. A good one.
« on: October 20, 2018, 02:23:54 AM »
So, Iíll be moving soon and am in the process of consolidating and packing.

Well I brought all my boards together and on a whim I counted them.

There are 76 builds in the queue.

Oops! Can someone say overkill.

Like I said a good problem, but no wonder I donít have any cash left to buy enclosures and parts!


How Do I? Beginner's Paradise. / Graphics Workflow?
« on: October 19, 2018, 11:20:47 AM »
Hey everyone,

My question is not so much about how to do something in any given graphics program. I am slowly figuring that out.

Rather, what steps do you take when creating your graphics.

I just feel like Iím making this way harder then it needs to be, although it just may be the program that Iím using (Graphic for Mac/iPad).

This is what Iím doing now.

1. Define a paper/canvas size
2. Define paper/canvas color
3. Choose create rectangle
4. Define Radii for rectangle
5. Create approximate size rectangle
6. Finalize rectangle size
7. Lock rectangle size

This is pretty much where my eyes glaze over and the drooling starts.

Is this standard fare that I just need to push my way through or is there an easier way to do this?

If this is normal then I have a few other questions.

Whatís next, do you populate your graphics with approximate sized knobs and switches or do you just measure off your exemplar enclosure and then base your labels and artwork off of measurements?

So, itís a bit crowded, but everything is within reach. Unfortunately, Iím moving soon and everything will get redone.

It was out in the ether for awhile before it posted.

I got the Idea from watching Brianís video intro to Madbean.

This is off to my right and my most commonly used tools.

When I get back all actually post pictures of my workstation after I clean up a bit.

Iím just always curious to see how other people do things and I always learn something.

Open Discussion / General thank you.
« on: October 15, 2018, 10:07:02 PM »
Just wanted to send out a general thank you to the members of this forum.

I was remembering back to my last career and The depth and breadth of knowledge to be learned was daunting. I was pretty much left to my own devices to learn it and that was a steep hill to climb.


I was just working my way through some of the tutorials and I was thinking about how awesome it was to have all of this information just laid out and available to consume.

In addition, there are numerous people on this board who have taken the time to answer my many questions, no matter how dumb, and also to offer encouragement and advice if not outright, tangible help.

All of this makes learning much more forgiving and easier to accomplish. I donít know how often you all are told that it is appreciated, but Iím saying it now.


Build Reports / Tube distortion
« on: October 15, 2018, 02:32:22 PM »
To borrow from one of Brianís earlier posts:

This build was poopy!

Of course some of this is PPPPPPP, Some of that was my stupid hands shaking and some came directly from Beelzebub himself.

I burned one of the capacitors soldering the pot on. Iím leaving it for now, itíll bother me enough eventually to where Iíll fix it. I slipped while drilling one of the breathing holes, The cheapo graduated drill bit tore a chunk of the part of the graphics and also made the hole eccentric. I also could not make the wire behave for the life of me, it did itís own thing as you can see.

And when I say it fought me to the end, I mean just that. For whatever reason, it seems like the star ground is always the last thing I do and I had everything ready to solder and I broke off the main loop.

I do like the graphics and it sounds good. I also like the breathing whole design. I stole that from myself from an earlier build.

The good news is always is that I learned things Did I will implement in my process from now on.

Just looked at the pictures it also looks like I need some smaller knobs.

 Please feel free to comment both good and bad. Constructive criticism is only going to help me get better.
