  Hey Guys.  Can I get some help purchasing capacitors?  Up till now, I have been making CIEM's using single drivers or turnkey solutions like GK, GQ, and Accupass.  I want to start experimenting with multiple driver combinations and crossovers.  I have a good assortment of resistors but caps are driving me nuts!  I've been looking on Mouser, but there are so many diff. values I'm going cross-eyed.  I think the main question I have is:  What voltage/temp rating do I need?   Is there a kit or bundle that has a few of everything I need?  I'd like to stick to ebay because I have some paypal money to burn...  
 
Would this get me started?

Are these listings for the CI-22955 and the ED-29689 on Aliexpress legit?

completely legit.
Soundlink is one of the biggest distributors of hearing aid supply in china. They are official suppliers for Knowles products and other stuff.
I talked to Grace in the chat not so long a go before buying things from them, she is very helpful you shouldn't be worry at all.

Cool, thank you! The prices do seem cheaper (slightly) than Digikey's, if you're willing to stomach the relatively long shipping times.

Soundlink is really awesome their customer service is the best I've come across.

Im sorry for the doublepost but i just had to show off my finsihed pair of ciem.

 

 
The seal and comfort are great the GK produces much more bass than i initially thought. I dont know if i like the red dampe in front of the tfwk though. The sound and resolution is really really great! I only now noticed that some of the songs i listen to are vynil recordings.
Im so happy that it worked out, i was not sure if the printer would be accurate enough but in the end all the frustration and hour i put in paid off.
Thank you guys and girls alot! Without you this project would not have been possible.

Did you try green damper on TWFK?

 

[Farquarl]

Did you try green damper on TWFK?

I did not, i just ordered the red one because it was recommended by vibrolabs. I didn't want to get into all the different driver and damper setups because the whole scanning and 3D printing thing was enoguh on its own. Does the green one allow a bit more treble?

Oh good! Im going to try out various dampers and drivers in my next Design.
Thanks for the good reference.

 

[omgflyingbanana]

Does the green one allow a bit more treble?

Yup, the green ones are 1500 ohms
 
while the red ones are 2200 ohms.
 
I found this reference to be extremely helpful: (EDIT: wow someone beat me to it. That was fast! 2 minutes too late.)

@Farquarl Awesome job!
How long were the tube you used and what diameter?
Also did you use a damper for the CI?
What is that cable and how do you find it (soft, flexible, microphonics)?

I'm still having difficulties trying to get a damper inside a 1,5 mm ID sound tube. I got a tip to buy this special tool to do it. I got something similar but i'm still far away.
 
I really want to do this, so this will be my main task to solve soon. I've halted the hobby over our summer times.

Does anyone know where to get that switch used on the Aether and Vision Ears VE6? I'd like to try switching between different tunings but I can't seem to find it on mouser.

I think they are from hearing aids, so knowles should have them.
