Here is another 10Y line stage with silver / finemet OPTVCs made by Tribute.
This one is a bit different since it has the volume control knobs separated for left and right which allows individual adjustment of the two channels.
It is also crammed full with input options.
3 balanced inputs. One of them with silver input transformers, two with copper inout transformers and 2 regular SE inputs.
The balanced connections are wired up to XLR and RCA jacks in parallel for maximum flexibility.
On the photos the line stage is equipped with Sylvania 10Y / VT25 tubes.
