The whine/whistling noise came back depending on where I moved the voltage boards and how hard I pressed, and pressing on Q1 even made it pick up radio stations!Pattyhttps://www.blogger.com/profile/00245135211069294292noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-16787307558051109382023-04-29T12:19:45.286+01:002023-04-29T12:19:45.286+01:00This comment has been removed by the author.Pattyhttps://www.blogger.com/profile/00245135211069294292noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-46287274226099291352023-04-29T11:52:46.604+01:002023-04-29T11:52:46.604+01:00Question about the 4k7 connecting Q1 gate to groun...Question about the 4k7 connecting Q1 gate to ground (via the 100k resistor) - the schematic has it as 47k, was the change intentional or a typo, and will it make any difference?Pattyhttps://www.blogger.com/profile/00245135211069294292noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-39294618634312020332022-11-07T09:20:56.623+00:002022-11-07T09:20:56.623+00:00Dog bless you for this list!

I'll share some of my experience with you! <br /><br />Here are some pictures of my Rusty Cardboard Box along with other documentation like my wiring <br />and some troubleshooting:<br /><br />https://imgur.com/a/4IvzIxM<br /><br />This is the first pedal I've ever built. So far I have only soldered some jack connectors together.<br />I've wanted to build a pedal myself for so long.<br />I don't know why I chose this. The simple design got me hooked and i thought: <br />"I can do it! I will do it! I will get the parts! No more excuses!"<br /><br />I've learned a lot about electronics, components and pedals in the past few weeks.<br />I was surprised that it worked the first time it was plugged in. That blew my mind! I was ready to debug.<br /><br />I'm deeply amazed by the results. I've never came across such an organic, great sounding EQ section.<br />The knobs really do something and feel like they let you adjust the overdrive in the 3 different bands.<br />You can get grunted mids while having clean-ish bass or the opposite.<br />The knobs seem to be interdependent. Really cool!<br />The Low-Hi switch seems to affect the higher frequencies. But in a good way.<br />You can get so many nice sounds out of this Box! <br /><br />To me, from clean to slightly crunchy, it even feels right when plugged directly into studio monitors without using an amp.<br /><br />I'm glad I chose this pedal as my first and not a boring TS808 or Centaur ;)<br />The next goal will be to include LEDs and to fit everything into a 1590B enclosure. <br />I think it is possible, but maybe some changes need to be done.<br /><br />------------------------------------------------------<br /><br />To save yourself some time if you want to build this yourself, <br />here is the parts list for the pedal without the power supply:<br /><br />--------------- Resistors 25x:<br />- 470R <br />- 680R <br />- 1.5 K 2x <br />- 2.2 K 2x<br />- 4.7 K 3x<br />- 6.8 K 3x<br />- 8.2 K <br />- 10 K 2x<br />- 15 K <br />- 18 K 3x<br />- 27 K 2x<br />- 100K <br />- 270K <br />- 1 M <br />- 1.5 M <br /><br />--------------- Capacitors 17x:<br />Electrolytic:<br />- 4.7uF 3x<br /><br />Film:<br />- 1n5 / 1500pF / 0.0015uF<br />- 6n8 / 6800pF / 0.0068uF<br />- 33nF / 0.033uF 3x<br />- 47nF / 0.047uF 3x<br />- 68nF / 0.068uF<br />- 100nF / 0.1uF<br />- 220nF / 0.22uF 2x<br />- 1uF<br /><br />Ceramic:<br />- 47pF / 0.047nF<br /><br />--------------- Transistors:<br />- Q1: 2N5245 or BF256B(confirmed by cylens) or J201(confirmed by Juanito) J211(confirmed by me)<br />- Q2: MPSA18<br />- Q3-8: MPS8598 or 2N3906(confirmed by Juanito) or BC557A(confirmed by MountBashful)<br /><br />--------------- Pots:<br />- A1M<br />- C15K (or C25K and 39K Resistor / or C50k and 22k Resistor)<br />- B50K<br />- A50K 2x <br /><br />---------------IC:<br />- TL071 <br /><br />--------------- Diodes:<br />- 1N4148 2x<br /><br />--------------- Think about:<br />- IC socket, transistor socket(optional. I should have done this to test different ones :( )<br />- 9V DC plug that isn't connected to the case. I don't want to advertise, but it was hard to find at first.<br />Something like "Schurter 4840.2200" should fit. I used something similar unbranded.<br />- Vero board^^<br />- Knobs <br />- 1/4in / 6.3mm mono jacks<br />- +/- 3ft(1m) wire for the links on the vero, +/- 6ft(2m) stranded wire for the cabling. Better get more!<br />- Switches. 3PDT or DPDT with or without LED?

If you want to make things a little simpler, just omit the JFET and the 100k and 47k resistor associated with it and simply connect your favorite spst switch to where the drain and source would be connected. I assume the reason why Yorkville used the JFET in the TS-50b amp - of which the rusty box is based on - int the first place is that they incorporated a footswitch jack as well as the front panel boost switch, and that they wanted to avoid signal currents to flow in the footswitch cable which would eventualy present some unintended capacitance to the signal chain as well as increase the risk of picking up extra hum and noise ;) The function of the JFET is just as a switch and has nothing to do with the timbre of the circuit - no mojo here!JBhttps://www.blogger.com/profile/02559562685214067431noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-35705096099967500552016-04-29T12:35:25.521+01:002016-04-29T12:35:25.521+01:00I've built a perfectly working Box so I'll...I've built a perfectly working Box so I'll share my voltages for whoever needs them.

I'm going to try with 2N3906 in place of the MPS8598 and I have some spare 2N5952 jfets from a phase 90 project, so I'll give one of them a shot.<br />Next question, where does the balanced output connect to?
