Hello everyone, stepping out of lurking status with this project - I'm stoked but need some help.
I'm building an M49 from the kit at the Tab-Funkenwerk site - with all of the metalwork, power supply, capsule, etc. It's my biggest step with DIY yet, as while I've built a few things previously (guitar pedals, CAPI VP28s) they've been from a more straightforward kit. I'm learning a lot and it's great.
I've found though, that while Oliver sends a parts kit with the mic, the parts included's values don't match with the component list and schematic on Tab's website (http://www.tab-funkenwerk.com/id89.html). It's difficult to get ahold of Oliver for answers about these, and I am considering just ordering parts that match the component list exactly. Here are my questions for folks that have done a build like this or have insight:
- Should I just order the parts exactly from Oliver's component list and be done with it?
- Have you used 1GΩ resistors in the build? (these aren't easy to source!)
- For C5, the layout says to use a 25µF 250V cap - but the 250V capacitors that I'm finding seem pretty physically large, and in Oliver's parts he sent is a 47µF 25V cap, and it looks like that's what's in his other M49 builds... Am I missing something with the 250V thing, or is that not necessary?
- Any thoughts or suggestions for the capacitor at the capsule (C1) and the output capacitor (C3)?
Thanks!
