A-113 normal operation and power

2007-01-19 by nicholas_kent

I just purchased an A-113 Subharmonic Generator used from Analogue Haven. I didn't run 
methodical tests on it yet. One of the first things I've noticed is works fine for only about 3 
midrange octaves of square input. Above or below it doesn't deliver suboctaves. It also 
seems to give up on vibrato. I just wanted to confirm if that's normal since I found it 
surprising not to see any specs on it's range in the  documentation that's out.

I've not transplanted it to another case to test yet but perhaps I have some unresolved 
power issues.

First off my case has a 230v A-100NT12 inside that I'm using the original owner's power 
converter on. I thought I'd ask again since while Dieter offered a warning about electrical 
danger on this group I still don't have an answer other than it's possible. I keep thinking 
I'd be better off running on 115v.

If so then let me rephrase the question. Would I be better off trying to trade my 230v PSU 
for a 115v one?

I think I still need to trade or obtain a new fuse, right? Since the 115v version uses a 
different rated fuse, correct?

Finally another factor is I'm using a 5V low cost adaptor, but the specs on that say it 
delivers 100mA and I've also got an A-191. So what would be an answer. I guess I could 
move my 5v modules to Analogue Solutions cases or would another low cost adaptor work 
in the same case, say a in different row? Or is 150mA within operating range?
