General Questions / Re: 5 nf Cap for Chunk chunk!!!!!
August 02, 2012, 09:24:10 PM
Keep in mind that the component numbering between the previous version of the CC (ver.2) and the current version is different. For the most recent version, I re-numbered the components to be more linear from left to right.

In ver.1 & 2, C15 is a 5n power supply filtering cap, not from the tone control. You do not have to use 5n for this. 4n7 is fine.

I really like #70 for components. You need to use a larger bit for 1n4001s, like the #65. #60 for PCB mounted pots.

The one thing about re-sharpened bits at drillcity: sometime they identify the drill size incorrectly. I've gotten a number of bits that were not exactly the size they were labeled as for whatever reason.

Thanks, I will add a layout image with the traces later today. Just an oversight on my part.

In reference to the schematic:

C3 + side towards R4.
C14 + side to pin1 of IC1A
C18 + side toward pin14 of IC5.

I see that you have the sleeve of the input jack grounded. Did you also ground the sleeve of the output jack? This is necessary when testing outside of an enclosure. It is not necessary to ground both sleeves once in an enclosure, provided you are using those metal frame jacks. This is because the enclosure itself grounds the sleeve of the output jack.

Great stuff here! I really like how you went the extra mile on these builds and put in your own ideas. That's what it's all about. The Orange Drop Muff is pretty wicked.

Have you checked voltages on your transistors? That may provide a clue.

The schematic im looking at, persumable the soulbender, is on the last page of the project file and most definitely has r10 - 10k.  The BOM says jumper...Maybe i should have specified, im following the single sided pcb etchable layout...?

Correct, but it also say on the same page "(This layout allows you to build the "Soulbender" or similar version – component numbering is slightly different than the schematic on pg.2)".

If following the single sided layout you should be using the component numbers and values listed on the last page, not the BOM for the double sided layout. The difference came from expanding the double sided layout a little from the previous version of the Pastyface to allow one to build several types of Tonebenders---not just the Soulbender.

So, on the SS layout, yes you definitely need to use 10k for R10...a jumper there would cause problems.

There is no 10k between the Tone and Volume pot on the Soulbender. If your tone control is not working unless there is a 10k there, then there may be another issue at play, perhaps related to the very low volume output you are experiencing. I'm quite certain of this as I compared the parts directly to a friend's Soulbender some time ago.

However, I did notice an error in the BOM just now. For the Sola Sound Tonebender, R10 should be 220k. I've made that correction on the project doc.

Try socketing C15 and use a larger value there. Start with 10n and work your way up until you find what works for you.

Global Annoucements / 07.27 - Double Flush in stock

The Double Flush boards finally arrived this morning and are available for order.

R5 should actually prevent the popping. The high value blocks current from discharging from the cap when the boost is off, but not completely, so when the boost switch is engaged and the resistor is shorted it doesn't pop. If you are using an SDPT for the switch, try tying the un-used lug to the middle one. If you already have done that, or it doesn't do the trick, try lowering R5 to 1M or 2M2. Let me know how it works out.
