Build Reports / Sunking v3
July 05, 2019, 05:53:28 AM
I've had this board sitting around for a long time. Then I was missing some parts. Then I finally got the "correct" diodes. And now I finally got it in an enclosure. Definitely not my best work and the off board wiring for the buffer is messy, but so it goes.

btw there is foam under the board.

Build Reports / Weener Wah completed
June 26, 2019, 06:35:04 AM
I had purchased a couple "broken" wahs off of ebay for less than a new shell. Most had minor issues but I was mainly interested in the harbinger 2 and the weener wah.

I took the inductor and used the pot, otherwise the internals were swapped. I added a rotary switch for the cap selection. It works. Hoping to give it a good run through this weekend.

I finally got around to getting the NomNom v2014 built. I fired it up and it passes sound but there is no phasing. I have the default diode in there and haven't tried the 4.7v Zener that is suggested in the doc.

I'm using a quad set of 2N5952 from Guitarpcb that I had gotten a while back.

Here are the voltages I am seeing

Source Voltage - 8.9v

TL074
1 - 4.10v
2 - 4.10v
3 - 4.10v
4 - 8.10v
5 - 4.10v
6 - 4.10v
7 - 4.10v
8 - 4.09v
9 - 4.09v
10 - 4.09v
11 - 0v
12 - 4.10v
13 - 4.10v
14 - 4.09v

TL072
1 - 4.09v
2 - 4.09v
3 - 3.90v
4 - 0v
5 - varied
6 - varied
7 - varied
8 - 8.10v

When I hook up the led the lfo looks to be working and it varies with the spd knob

Q1 - 2n5087
e - 4.10
b - 3.55
c - 2.45

Q2-Q5 - 2n5952
g-4.10
s-4.09
d-3.40

They are all reading the same give or take a hundredth of a volt. The voltages look odd to me, but I'm not sure why. I have a working smoothie that I haven't tried reading voltages from yet...

I have some 2n5457 that I am working on matching and will try those later.

Any suggestions? Sometime fresh eyes help...

Thanks for any help!

Build Reports / Aristocrat finished
December 23, 2010, 07:35:31 AM
I finally finished up my Aristocrat last night. I got it crammed into a 125B enclosure. The stompjacks are close, but its the best I could do.





I'm going to have to order some other boards soon...
