"Thank you for the reply! I have been searching the usual websites for parts, Digikey, Farnell, Mouser etc but can't seem to find the Slot 10 5 10's. Did you order directly from the Coilcraft website? You wouldn't happen to have a reference number for the parts? I live in Iceland so shipping is a big headache when sourcing for parts. I'm already up to 3 different sources so far for this build... When removing the YAEWSBM, is it not necessary to change any other part values according to the schematic? Regards, Kolbeinn"
Iceland! That is amazing. Its one of the places I plan to see some day. I am in Canada and suspect its much easier for me to get things.
As for the Slot 10's, yes I ordered them from Coilcraft, and I must say they are the nicest people I have ever done business with. Here is a link to the item in question:
The coils can break when you are adjusting them, so I HIGHLY recommend ordering several as replacements (I broke 2, but had 10 left, so no great loss.) and get the little tool which they sell (cheap). I had originally ordered extra as I have been planning to build one of these for my brother as a gift. Its taking a long time however.
There will be some resistor changes that you will have to do to compensate for the different coils. Thierry, who has some great wisdom on this subject, listed them somewhere on Thereminworld, but I will quote him here:
"R2, R6 and R16: 1.5k instead of 2.2k
R15, R19: 330 instead of 470"
And here is the context / link to thread:
I wish you well on your project. I will try to help as I can. I am not an engineer, but I have some experience, now, that I am happy to share (mostly what not to do).
PS. sorry I almost missed this part.
"When removing the YAEWSBM, is it not necessary to change any other part values according to the schematic?"
I looked over the schematic in "Hot Rodding your etherwave," and checked to see what differences there are between that and the added YAEWSBM, and it seemed that it was just a simple addition. Quite easy to remove, and fix the traces (in Eagle at any rate) and then jump the gaps with wires. Ugly but worked.
It did work with YAEWSBM but it was more silent then it currently is.
If you get it working let me know!
