It can't hurt to sent Peter Rucker an email and ask if he has the switch in stock and would sell you one.

VFE Projects / Re: Triumvirate Build Doc Confusion
« on: January 05, 2020, 09:55:05 PM »
in general, the documents are to be relied upon over the print on the VFE pcb, since some tweaking was done even to the finished VFE boad designs.  I think you are OK with a polariazed cap for the 10 Uf fix.    I also found the reference to the pwr capacitors confusing when I started building some of the VFE pedals, but at least that is a consistent part reference.

Thanks Brian for making the big push to get the projects up for order and the new build documents posted.  I am looking forward to putting a couple of these new projects together during the holidays, and I imagine a few other folks here are planning to do the same thing.  Best wishes to you and yoru family for a great holiday too!

VFE Projects / Re: IMC no longer included w/ Tractor Beam board?

My recollection was faulty on that piece no longer being included.  Sorry.

it is an error in the build doc.  the supply of that pot ran out over a year ago, I believe.  I think the BOM notes it needs to be ordered but the text of the build doc still refers to it as included.

I am enjoying the new write-ups and expanding my shopping list.  : ^ )

Thanks for the update!

As much as i want to avoid putting any pressure on anyone about when something will be available on the site, I would like to ask generally if we are days away from the new projects going live?  Or weeks away?  I would like to curb my hourly checks on the shop page if they are premature.  : ^ )

VFE Projects / Re: VFE Bumblebee troubleshooting
« on: December 02, 2019, 10:17:08 AM »
Updating my post about this issue in case it comes up for others later in a search.  The problem I described in the first post was due to getting the power connections wrong between the switching board and the main Bumblebee board.  The read the markings on the main board for "V-, B, and V+" to mean "V-, G, and V+"    That is not correct.  The connection diagram shows that the 3 wires from the switching board that are "G, V-, and V+" should connect straight across to the three holes where the v-, b, and v= markings are.  When I followed the diagram instead of trying to use the markings the power supplied to the main board was correct.

VFE Projects / VFE Bumblebee troubleshooting
« on: November 21, 2019, 09:30:42 AM »
Finished assembling this pedal and now troubleshooting an odd problem.  It is a split-rail design, and when powered I am only seeing -1.2 volts on the negative supply.  If I disconnect the negative power going to the main board, the output from the charge pump is OK on both the positive and negative outputs.  What I then see is that I am getting about 3.5 volts on the negative power traces on the main board with all of the transistors and the two ICs removed from their sockets.  Also getting the same 3.5 v on the negative circuit path when the transistors and ICs are in place.  I am looking for unwanted solder bridges but have not yet found any.  Since that is about 5.4 volts less than the positive voltage going in to the main board, does the voltage reading itself suggest any particular places or parts to check on the board?

Does the trimmer adjustment for the nom nom change the effect you are describing?   And can you hear a difference using the second trimmer to adjust the feedback?  I would try playing with those some more to see if you can get a better overall sound to your liking.

Mine is apprently in the mail, so no problem here.  But good to know that a few other folks won't be disappointed.

maybe the octave is a feature instead of a concern... : ^ )

No surprise to see that the Snarkdoodle boards are gone.  : ^)
