There are no tubes in the Concentra, if you mean the 15pin connector and there is only one by the, and it most certainly not a tube.
the two silver boxes are transformers that create the balanced signal for the amp.

Stupid amp. Why a thousand bad sounding IC's when it's easier to make a transistor amp, or even a tube one.
