PS Audio 200C X vs. 200Delta?

Not a problem Eric, I thought that you might not need it anymore, but it could answer for someone else at another time... by the way, I did not mention,  If I remember correctly, I sold Delta 200's in my own store in 1991.

the 200C and Cx ran the rails right at the voltage limits of the caps, so worked the caps pretty hard. May be in need of a recap.
Both versions did offer lots of power...

I've had too many amps come through my hands over the past couple of years.  I have a 200C now. Hence me looking around and finding this post.  I haven't measured rail voltage, but I did check the caps.  They all measure around 16,500 mfd each and are 75volt parts, no signs of leaking.  I may replace them soon,  but they sure look good. I've been considering replacing a few of the small electrolytic on the boards.  I figure that I'll replace filter caps at that time. I'm a speaker guy and don't claim to know much about amps,  but I'm thinking "why not" on some parts changes.  This amp already sounds WAAAAY above its price point. 

I agree, Tim. A 200C can be had for $400-$500! The thing weighs a ton, with a massive transformer and power supply. Built like a battleship, as they say. I use it on my Magneplanar Tympani and Eminent Technology LFT-4 bass panels. 200w/ch at 8 ohms, 400 at 4.

I don't know if you guys are being updated on this thread, but if you replace the bridge rectifiers with IXYS Fred's your amps will actually sound a good deal better. You can look around the web, one guy found a replacement for the relay that doesn't chatter, another made a DC power supply for it. I bought the quiet one but don't recall the ordering information.
