Working on a Naughty Fish, and was having some trouble with the power. The Voltage as read from the jack keeps bouncing between something like 0.3 to 1.5. The LED1 (showing if the pedal is on or off) just flashes instead of being a steady on. Could this be a problem with the diodes? There doesn't seem to be any ones that are burnt out. The 1N5817 does seem to have continuity to ground on both sides? Thanks!

General Questions / DeadEnd Meaty Balls Rotary Switch Settings
April 16, 2020, 04:09:25 PM
Just finished up the Meaty Balls build, however I'm not getting any effect. There is wet signal passing through but not envelope effect. I believe I have the Mode rotary switch set up incorrectly, which is causing the Vactrols to not activate properly.
I used the 3P4T rotary from smallbear which has the selectable number of posistions, however, when the selector washer is placed in the hole marked as "2", the switch full rotates into all 12 positions, and I only need two for the Mode selector. So I guess I'm asking the correct setting for the selector washer on the switch in order to create the correct connections for the signal to be passed into the Vactrols.

Tech Help - Projects Page / Rustbucket Incorrect Trace?
March 29, 2020, 06:18:43 PM
Been dealing with a faulty Rustbucket for awhile, and I've come across something which doesn't seem right.
Currently getting a super distorted signal out of Pin 1 of IC1, and I was reflowing some of the joints and checking continuity of the parts around the IC and noticed something weird in the R2/3/4 area. I think there might be an incorrect trace on the PCB between R4 and R2? I've attached picture of the back of the board along with an annotation on the trace diagram which shows where I see the trace. I am also measuring continuity between these two points, which seems incorrect. Would love some guidance here, thanks!
Also, currently, all voltages for IC1 are correct with the ones provided in the build doc.

Open Discussion / Favorite 1590XX/1790NS Projects?
March 28, 2020, 04:32:30 PM
Pulled out an extra 1590XX that I had lined up for a customer that bailed, so now I've got a nice blank enclosure to put something in with all this new free time. What are some of your favorite 1590XX projects that I could put in here? Open to anything!

Tech Help - Projects Page / Rustbucket Signal Stopping at MN3007
March 16, 2020, 01:59:31 PM
Just finished my Rustbucket, however I'm not getting any wet signal.
Audio probed and got to pin 3 of IC6, the MN3007. All of the output pins on the MN3007 just give a static-y cycle noise. Checked all voltages and they match up.
Is it possible I have a bunk MN3007? Ordered from it from Small Bear, or is there another problem that could be causing it?

General Questions / Naughty Fish stops working in Band Pass.
December 23, 2018, 05:11:48 PM
Title pretty much gives the gist; the pedal works perfectly in Low Pass and High Pass, but when Band Pass is selected, it stops working. I've audio probed it and the problem comes IC1-B, sound enters the chip as normal, but the exiting sound is virtually non-existent. This only happens in Band Pass, the IC functions normally in the other settings. The indicator/status LED at the top of the board is also always on, but dim, when it's in Band Pass. The only modification I've made is moving the Up/Down switch to an offboard footswitch. Any ideas of what it could be? Any help is appreciated!

General Questions / Aion Refractor Low Voltage
August 13, 2018, 04:50:36 PM
So I built a Klon awhile ago, and it's just starting to act up.
Here's the documentation: https://aionelectronics.com/wp-content/uploads/2013/11/aion-refractor-centaur-documentation-v2.pdf
The problem is coming from IC2 (TL072), that's where the signal stops, and the voltages look really wrong:
1: -8.15
2: 3.56
3: 4.25
4: -9.28
5: 4.25
6: -8.13
7: -8.2
8: -8.17
There's no +18V coming in, and I think that's the problem. I'm not sure if it's somewhere near the IC, or somewhere near the charge pump.
Here are the charge pump voltages (TC1044SCPA):
1: 9.3
2: 5.53
3: 0
4: -3.75
5: -9.28
6: 4.5
7: 5.97
8: 9.7
The correct amount of voltage is getting to the PCB from the DC Jack, IC1 (TL072) is working fine. Any help is appreciated, thanks!

How Do I? Beginner's Paradise. / PT2399 Not Adding Delay
May 30, 2018, 06:47:54 PM
So I'm finishing up the Deep Blue Delay from Aion, and I can get the delay to work. The pedal passes signal fine, but when the pedal is on there's no delay effect. Schematic https://aionelectronics.com/wp-content/uploads/2017/11/aion-vector-deep-blue-delay-documentation.pdf
I've tested the Delay in at pin 15, and there's signal going into the IC. At pins 8 and 9, there's just a popping sound. Maybe this is the problem?
The IC is receiving 5V at pin 1, and I've swapped out the PT2399 to no avail. Pin 6 to Ground is measuring ~41K Ohms. Is this the problem? Maybe someone else can help? Thanks!
