I stumbled across the website before but I lost it.  I know the 2 populated boards below are jensen 990 opamp  designs but the layout is different and so is the pinout.  Anyone know who makes it like this? I rather like it as the spacing makes it easier to work on.

Beautiful little layout on those buggers too.

Steve Hogan.  Worked with Deane on upgrades from the original 990 circuit amongst many other Jensen related thingies.

Good choice  :)

Yes smart guy for sure.
This box is at the studio.
It’s a pair of tss-990c’s wired to be a volume controller with dim, mute, mono stereo switch, 2 x selectable inputs, 2 x selectable outputs.  It’s running off an opamp labs bipolar 24vdc supply. Sounds great
