MOTM

a) I have never seen a +-15V regulated wall wart. I have seen +-12V (they 
use a 5-pin DIN, a la MIDI). But this will not work with MOTM.

b) your best bet is to get a 5U tall case, put a MOTM-900 in there, and 
leave it. Then, when needed, remove modules from
the studio and place in there.

The smallest PowerOne that 'should' work is only about $50 (US$) as long as
you need less than 400mA:

PS - PLEASE understand, fear and respect AC current before attempting DIY
power projects! Death awaits just a tiny stupid mistake away. (I've been
REALLY lucky at least three times in my life . . . and I'm not generally
stupid . . . unless it comes to credit cards . . .and especially women! ;-)

This with one of Paul's distribution boards and you'd be in business. 
Personally I'd rather be using Paul's 900 hardware than this however.

Cheap, 240ma, +/-15v - I'd just have to deal with the 5-pin DIN in some
way....

What about the Dotcom QPS2:

could easily switch out the power connectors with the MTA 156 ...

Switching power supplies are unbeatable for size and weight.

They tend to be noisier than linear power supplies, but will the
effect on your MOTM modules be large enough to be noticeable on
stage ?

Hi all,

I'm finding a clicking in the outputs of band 1 of my motm410. It  
clicks at the same rate as the built-in LFO, when it hits the low and  
high point of its cycle. I get it in Out 1 and Mix Out but not Outs 2  
& 3.

It might have always been there, but recently I've started using that  
filter to process guitar, so the signal is rarely the full 5v, and  
there's no envelope shutting off the output when I'm not playing.  
When I put a full 5v osc. signal through, I don't hear the clicking  
at all. Probably still there but to far below the level of the signal  
to be audible.

Do other people find this? I'm wondering if this is just a  
consequence of the filter design, or is there something wacky with  
mine specifically?

thanks,
Matthew

Something is wrong, I have never heard of this in 8 years for shipping this 
module.
