This is a very nice looking vintage tube amp made by Philips in 1951. It was not designed for hifi but for PA purposes. It has quite a complex circuit that features clipping prevention and power optimalization. Good for 70W with a pair of EL34 in class B on 800V plate voltage...
'american' style

10V - 100V speaker output
a huge power transformer
All tubes glowing. The AX50 mercury rectifiers must be warmed carefully
99% original parts, almost all capacitors are leeking
I don't know yet what to do with it. As all capacitors are leeking I didn't switch on the high tension yet. It is a difficult circuit and certainly not suited for domestic hifi use. Modifying the circuit into something more practical is possible. However, it will then loose it's originality and may be it's collectable value.
