Regarding adding the GSSL sidechain circuitry to the 552 VCA's :
This week I have ordered a couple of Turbo boards. I'm going to turn a 4 channel SSL SL595 line amp (that uses VCA's as outputfader), into a GSSL compressor. Not sure when I'll be finishing it, but if it turns out well, the same modifications can be done to the 552.
Done the first tests today, it's promising to say the least.
I made a mistake on the GSSL board that I used for the experiment. The -12 v rail doesn't supply -12v (probably just a minor thing), but the SC circuit appears to be working.
The 552 compresses, but I have to do some tweaking to get it right. I'll set up a complete GSSL audiochannel, to make comparisons, and of course to be able to compare the compression ratios and settings while tweaking. But basically, it works.
Just so you know !
