one of my favorite 'old-school' Phono/DJ mixers that I use for listening is in need of some surgery.
It's an old Gemini MX-2200 mixer.
Really cute little fella that in the past worked great as my phono pre-amp for listening & sampling.
As I was fixing a couple cold solder joints on the PCB last nite an idea hit me...
Being the geek I am, I thought it would be cool to rebuild this puppy completely & replace the cheap crappy electrolytics with some high-end caps, same goes for the rest of the parts, since really there aren't that many.
Matter of fact I already removed all the old components & inventoried them!
I figured replace the caps, op-amps & even the resistors with high-end precision ones.
I noticed it uses JRC 4558DD OpAmps which are pretty crappy for Hi-Fi/studio use (from what I have read).
Does anyone have any suggestions as a drop in replacement?
Would NE5532 or NE5534 work (I have some spares from a past console re-cap project).
I am just wondering if replacing the caps, resistors & opAmps would bring about worthwhile results.
I was thinking Blackgate caps (or would Xicons be good enough?).
Not sure if repacing the ceramic caps or those "chiclet" looking caps are necessary, any one know if those are worth replacing?
If this works, I bet it would sound great.
(and look real cool).
Comments & suggestions from some of you DIY wizards would be greatly appreciated...
Also, if anyone can suggest a good place to buy high-end parts at decent prices, do tell...
