Sorry, I´ve been busy. It will take a few more days ´til I find time to do it.

Here are some pictures of the Gl122 PCB:

Both electrolytics are a bit big for the PCB. They were newly installed back when I recapped the desk. In original state there were 2x 100uF/6,3V tantalums parallel instead of the smaller 220uF electrolytic. And the other spot had a 100uF/6,3V tantalum as output coupling cap which has been replaced with a 470uF cap. The red Wimas are 0,1uF bypass caps.
