Hi Everyone, Now that the 832 amps is finished and working fine...I needed to start something else. Here is a photo of the thing. It is clear that some serious power is involved. A pair of 6AS7s and a pair of 6SL7s is fairly serious. The absence of output trannies is sort of a give away. So what is it? A headphone amp. SRPP input stage and SRPP capacitor coupled output stage. Yes 6AS7s will work as a SRPP. 240 volts B+ at 57 ma. Now if the math works it can deliver +/- 15 volts into 64 ohms. That is serious loudness as many phones only need a handful of milli watts. If it doesn't work as a phone amp, it will be one humongous line stage. More to follow as it gets built.
