Hello all, new member here.  Here isthe situation.  I attempted to build the tmb ef86 mainly using parts I had lying around.  Upon completion what I ended up with is low output on the tmb channel and nothing on the normal.  After double and triple checking connections, resistor and cap values statist the layout, solder joints, and rolling tubes to no avail, I was wondering if anyone could post a voltage chat as it would be very instrumental in helping to nail down the problem.  Thanks.  p.s. A schematic would be very helpful as well.
