OTOMON LAB 2A3 drive GM70 SE tube amplifier 28W power Zero NFB (O. U. D. D. C)
Driver tube is 2A3, prestage tube is 417A. No NFB (switch let customer use NFB -3db, very little for another music enjoy) Very wide range, rich and beautiful bass sound as characteristic of O. C (OTOMON Ultimate Direct heat tube Drive Circuit, detail in OTOMON LAB website) Response frequency is flatted from 20Hz at 28W of power. This is impossible thing as using interstage transformer to drive triode tube. I used the same output transformer in schematic using interstage transformer, at 28W, from 20Hz to 60Hz, it drops 3.5db.
Specification: No NFB mode Output : 2830W. Noise : under 1mV Response frequency: 20Hz35K Hz (flatted) at 28W 16Hz 55K Hz(-1db) Distortion: 0.2% 1W 5% 28W Can be match with almost speaker, and all genre of musics.
Detail and Powerful sound, very rich of low frequency with musical sound.
