Hi all ,
After, a few pleasant experiences, with valves, decided to build, a new audio PP amplifier, more powerful, and with better, THD under 0,3%, P=50W, Raa=6k6, Bf=10Hz ..... 100Khz and power supply HV=+500V , schematic attached . Also new design of cabinet, and quality components like Vima polypropylene capacitors , Alps potis , toroidal output transformers from Toroidy (poland) , metalized power resistors, Nichicon , Aero elco's and new ECC83 and ECC82 valves from Electro Harmonix, output tubes EL34 from same brand.
Printed board circuit designed by me and Dano, factory made in China . It was a great success, very good sounding amplifier, so I built an another one and, stil waiting transformer cover, from EBay . Right now, it's in burn in, state drawing, a pair of Taga Harmony Platinum F-120 speakers . They have SPL=93dB, 6 Ohms and P=240W .
Regards,
Alex
