Re: a 138 vs WVX

2006-08-22 by untiedstates

Hmmm.. I'd asked on this group previously about the A-137's behavior -
 needing a musical description more than a technical one.

So, along the lines of this discussion, and because the Bananalogue
page mentions that for the WVX "The signal from Out 1 of the top
section adds odd overtones.....The bottom section is a full wave
rectifier, transforming waves to positive voltage with even harmonics."

... what is going on in the A-137 re: odd and even harmonics?

- this is useful to know because, for example.. tube amplifiers only
add even harmonics... the sounds of closed-tube instruments such as
organs only have odd harmonics... etc..

????

thanks. -bryan
