First, show the quality of my hand made front/end panel work(first two sets in the picture below). The last one set is FrontPanelExpress' commercial custom drilled ($40+shipping) panel set as reference to see how good my work is.
Second, I used AMB default part list and made the version what I called "Standard Version" of my Mini3V2.
Third, the "Premium Version", exactly matched resistors across LRG channel and use the stock TO-92 package of TLE2426. Polyphenylenesulfide(Yes,NOT polyester film!) caps for bypassing, all metal film (no oversize) resistors on the circuit board....
Fourth, here is my extreme edition of Mini3V2 which I built long time ago. All resistors(Vishay Dale as first choice) position across LRG are matched to exact same reading on my B+K 2706A DMM, Switchcraft jacks, SO-8 TLE2426 for lower noise, polyphenylenesulfide(Yes, NOT polyester film!) caps for bypassing, all metal film (no oversize) resistors on the circuit board........ Oh, one more thing, don't forget file that damn battery clip as this happens to all my four 1455C801 cases and AccuPower battery.
Nothing fancy frontview.
Internal view.
After couple hours burning this little baby, I admit its sounding is excellent!! My view it is on the performance par of USD$300 range commercial amp.
I have looked into the details of the difference between SO8 TLE2426 and TO-92 TLE2426 . In Ti's datasheet it only says the SO8 version provides "The performance and precision of the TLE2426 is available in an easy-to-use, space saving, 3-terminal LP package. For increased performance, the optional 8-pin packages provide a noise-reduction pin.
With the addition of an external capacitor (CNR), peak-to-peak noise is reduced while line ripple rejection is improved.".
Fifth, see my extreme edition Mini3V2 in action with Apple IPOD 4G, my hand made Orange IPOD LineOutDock(99.99% pure silver wire with top quality SwitchCraft 3.5mm plug) and Sennheiser HD650.
