I'm going to be building my META42 soon and here is my parts list.
Current Source: Nomade Jukebox 3 --> CMOY --> Sennheiser HD 580
POT - Panasonic 10.5k (Max resistance)
R1 - 1k
R2 - 105k
R3 - 470
R4 - 4.7K
R5 - 10k
R6 - 1M
R7 - 100
R8 - None
R9 - None
R10 - 100
C1 - "Alt. 1.0 ìF 100V+ metalized polypropylene film capacitor"
C2 and 3 (4X) - "1000 ìF 10V 16mm tall long-life electrolytic capacitor, radial"
C4 - "Alt. 1.0 ìF 63V metalized polyester box cap"
C5 - None
D1 diode will be included
4 JFET Transistors included
Power Supply - Mouser part # 412112103
HI-Q AC Adaptor 12V DC 1 AMP
Just need to check some stuff.
My R3 to R6 resistors are actually taken from a thread at Headwize (META42 Success) and I plugged it into Tangent's calculator and it says that has a Gain of about 10. Since I'm using the OPA637 the higher Gain will be more stable.
A quick PSU question. What AMP is best for the META42? I notice there are a bunch of different ratings for 12VDC adaptors. Will the one I picked work well? I can just wire it directly into the V+ and V- spots on the META42 right? No special things in between needed?
Anyone have suggestions on changes before I place my order?
Thanks.
