Classic-vintage SE amp with triodes 26-27/YO186, dvb xfmrs

A friend of mine (Bogdan Rosca) did this recently and asked me to upload some information about his construction as he's not so used (yet) with forum activity.
The input, interstage and output xfmrs are made by me, so you know who to put the blame on 🙂
The test is made with a Lowther full range and a mike Umik 1, otherwise on a resistive load the response is pretty linear even if the signal is processed through 3 audio xfmrs per channel 🙂
