Hi guys,
I've just "finished" putting together my Pimeta and I'm getting a serious DC offset!
I plan to do Class-A, but have not installed the JFETS yet.
I wanted a gain of about 4, so here are the components used:
R1R/R1L : 4.42k
R2R/R2L : 1M
R3R/R3L : 3.32k
R4R/R4L : 10k
R5R/R5L : 10k
R6R/R6L : 1M
R8R/R8L : 0 (Jumpered)
R10R/R10L : 1k
R11R/R11L : 210
R1G: 4.42k
R3G: inf
R4G: 4.42k
R11G: 210
OPAG: AD8610AR
OPALR: AD8620AR
BUFFERS: 1 for each BUF634P
D1: STPS1045D (The other one on Tangent's part list)
The DC offset (latest):
OG to OR: 5.72v
OG to OL: 4.99v
Any ideas??? I'm totally confused as this is my first serious build (asside from a working TREAD).
Thanks!!!
