Subject: MOTM-101 output level and a question about mounting.

Hi
Sorry if this question has been brought up before, but I´ve been
searching the list for a while and can´t find a clear answer. The
thing is that my newly build MOTM-101 SH has quite a low output;
around 100mV on the white noise out (Trimmer TP1 at max measured
with my Wellemann DVM891)and this gives a maximum SH output (with
noise as internal S/H source) on around .7 - .9 Volts. (with "Level"
at max setting) According to the manual I should get higher levels,
but here it says that the first OP-AMP after the noise diodes has a
gain of 100, as I se it its only 10 - 100k (R4) / 10k (R3). Could
I just reduce R3 (to 3,3K or something) or should I check a 4.th
time if everything is rigth, maybe check-measure resitors? I would
like a bit more out of the S/H to modulate filters.
Apart from that, as a new MOTM user I can only say I´m a fan. Fan of
the sound, fan of the quality.
Which brings me to the next question. Mounting in 19" racks is nice
and easy but I can quickly se this sytem grow, wich means high racks
or broad cabinets (dot. com style)What do you guys prefer - broad or
high?
Or maybe the system goes so big its gotta be both. But then I´ll be
broke.
