It is old but still played well with body and soul. My ATOC9 sounded thin in comparison.

Just completed the phono stage and power in up with a v2...not enough gain for Supex 909 which has 0.2mV output. Anything I can do to increase the gain further?

Strap your best quality 1000uF cap across the first stage source degeneration resistor. Its plus side up. Can even be a 10V cap. That will add 100mV RMS to your total output. +5db in your situation. What is the gain of your pre, main amp, and what is the sensitivity of your speakers?

Should that be a really good cap? Sometimes you can find oscon caps on old computer motherboards, would those be good in that position?

I have used such. 6V ones. Good, but a BG NP alone or a Nichicon Muse NP bypassed with Teflon are audibly better by the inverse order I referenced them. Note, its not degrading the result, its interesting how it manipulates tone.

10w T amp with a B1/LDR preamp with no gain. That may be why I have not enough gain.

Speaker is high efficiency fullranger +subs + supertweeter.
