Hi
I presume the UK is too far from Brussels?
I am planning to check out some DL1656 next week.
I think most of the caps are tantalum which do not need changing, so you could just replace the electrolytics and be done with it. Unless you have changed the VCA chips or components in an inout stage readjustment is not really necessary.

ok just looked at a unit.
There are 8 electrolytics, 2 big reservoirs and 6 little ones.
Change then all for new items but do not change the capacitance value of the 6 small ones particularly.
The reimpots are factory fixed and do not need adjustment unless components in their vicinity are changed. There are 2 distortion trims and some common mode trims for the input (resistive and capacitive). Others are to adjust the metering.
