Hi,
I've also just aquired a 2nd hand (silver knob) SEG, and use it as a pre-amp. This thing really rocks, love the sound, but I also found out that the output volume is kind of limited.
So the questions goes to Stan:
I use it with the supplied 12v transformer, but I can use a high quality power supply (Zetagi HP156S) that can supply 15V. The manual say the max voltage is 13v, but you've stated in several places that you run them on 15v - do you need any mods for that, or can it be used with 15v stock?
What upgrades are available and what are the costs involved?
What are the differences between the original SEG (the one I have) and the new one?
What upgrades do you consider to make the most difference?
