Cary slp 98p upgrade

Schematic should be somewhere. Need a switch for the front to, if it's not already there.

I had two thoughts. Let Cary do the upgrade and while it's there have it upgraded to F1 specs. 

My SLP-98 is upgraded, partially by myself, and originally from Cary with better parts than the old Upscale F1 upgrade from a decade ago.  Here is my recommendation, fwiw.  If you are not sure, stop here and send it to a well practiced tech with proper measurement equipment.  It's not just about slapping in parts and crossing your fingers.  There are other things they can check while they have it open.  It will be totally worth it if the tech knows what they are doing.  

@dpm2340 hoping you chose the right parts for max benefit and reliability. If you get stuck and need a good tech, I might know of someone to recommend via DM/PM privately.  The 98 is totally worth upgrading if done properly.  Best of luck.

Thanks for making me feel old....LOL. I guess I won't talk about my Infinity RS1Bs anymore...

Hehehe, ooops. @russ69 Sorry 'bout that.  Well, if you have an early original F1 98, there are better caps, other bits inside, v-control, wiring, and a few things to upgrade inside bringing it to yet another level. Encouraged a friend and he had two 98s sitting side by side with my former Cary amp, testing, comparing the F1 and newer upgraded SLP-98 version. A notable difference, like lifting a veil off it all, deeper larger soundstage, more texture and tone.   It was so good, he had another $17k CJ preamp prepping it for resale recovering funds $. A nice surprise for him.
