has anyone built an ssl with dbx 2150a's (curious)

I am just wondering if anyone has built an sslg using dbx2150a's not that2150a's.

I have just finished on over the last 2 days and i had to make a few minor changes as in lowering the control voltages in the vca's as to achieve correct ratio's etc.

thanks

Our original prototype back in 1990 was based on DBX2150's..

Hi Jakob,

How do you think they compare with others available? It's just that I have tried with that 2150a's and i feel there are suttle differences.

The That2150's are probably a newer - and thus more well-behaved - chip-technology. When adjusted into minimum distortion I feel that the DBX and the THAT perform the same - but unadjusted the DBX's has more artefacts to show. And I kinda like the things that happens when the VCA sound isn't nulled out.. :razz:

But then again, YMMV

I built my first SSL with DBX 2150 chips... less clean/pristine comes to mind. I also used generic electrolytics so that can contribute, too.

Yup - less clean describes it well..

Hi Ben, I am just troubleshooting one with 2150s and am having some issues. Can you share what these changes were that you made, please?

cheers.

I just built two with 2150s. No changes are needed... except a ratio calibration. I prefer SSLTech method. The thread is listed in the SSL META. Nothing else needs to changed. :thumb:
