If it's not difficult, please draw a diagram of your attenuator with a 1K resistor?I used 1k pot with two Cinemag 30k:600 output models, 5:1 Edcor and some home made 5:1 to try them out. 1k pot works well in practice although T pad is a bit better. Especially when very good transformers are used and one wants the rest to be as good as possible. "The problem" with Redd47 is very limited gain range, not lack of gain with 46dB max, it really needs an output pad.
Did anyone notice how sound is changing when switching gain positions? At higher input levels 34dB position sound kind of falls apart a bit, i like 40dB best, 46dB has more of sometimes annoying high frequency distortion. I never tried to extend the range of gain switch for this reason, maybe it is something to try out and hear how lower than 34dB of gain sounds. IIRC, this is what Chandler did down to 16dB while retaining stability.
