Amazing good iron inthere you can put 20hz square waves though it. Main voltage / OPT output change is really smart. When you need more power the tl50 is same quality.
They know how to build good amplifiers and the internal structure is a feast for the eyes. Congrats

Then I can also add a Siemens 12AU7 with similar material used din plates:


This one has Siemens Munchen codes on it (Gf1 ≠3D) but was branded Telefunken. A part of the logo is still visible. It has a very nice airy and detailed sound, maybe my favourite 12AU7.
