So guys,after all these years, I will finally have my first ms amp( I bought whitenoises') ms275- I have years of experience with all ZX models, ti models, newer ti models, so what can I expect out of this lil amp? Opinions,suggestions? Btw, I believe the amp is/has been modded by trickyricky

MS 275 is one of my favorite small amps. Sound awesome on a set of components with plenty of headroom or just enough power to run a single sub. Also very versatile and you can run it at lower impedances by using the internal yellow/red switch and switching it into high current mode. The fact the Tricky did the work on it is an added bonus.

I believe i only replaced the filter caps, don't think i replaced the Op amps or did any thing considered a mod. It got new thermal compound that's for sure unless it has the thermal pads.

And last question,(2), I can't find in any of the Manuela the yellow/red switch, so which is for what? & specs show only 2v I put,( later models , ZX , ti etc, 6 volts, but can easily handle 8 volts) what is max input voltage as I do use a sld44 line driver, and THANX IN ADVANCE

yellow is for normal operation (normal loads). red will limit the power supply voltage so you can run it somewhat high current instead of high voltage (2 ohm mono).
I don't know exactly how much input voltage it can handle but I do know it will take more than 2 volts.
