Audio Research CA50 + tube rolling
If your output tubes are still strong: Try some Amperex 7308s, like these:(http://www.upscaleaudio.com/Amperex-7308_p_100.html), in the driver positions first. If that provides what you consider an improvement(it's almost guaranteed to); buy some ... 
What is the affect of cd player?
Shakey- You mentioned that your Sony was modded. Obviously you would agree: They take modding(especially those OS-AMPs) to sound good. What was the original cost of your Sony and the final expenditure, before you were satisfied? I know the popular... 
HiFi tuning fuses, some benefits help
I had to describe the improvement as, "More organic". Not in any way, "colored". Rather simply more, "alive". ie: More wood from a Double Bass, rosin on the bow, skin from drums, breath and chest resonance on vocals, etc. Subtleties for certain, b... 
Good $250 Power Cord
NASA- I agree it would be nice if they posted pics. Think of all the storage that would consume on their site though(They've quite an inventory). 
Good $250 Power Cord
Try whatever your heart desires, then a Synergistic Research AC Power Coupler. I'll bet it's the one you'll keep. Opens up the sound stage, great dynamics and solid, fast bass drive. With or without the active shielding, they are great PCs. You ca... 
AC power cord for Rotel RCD-1072
Find a used Synergistic Research AC Master Coupler, if you want a real improvement in those areas. They aren't that much more expensive, and it's a cable you can keep using when you make further upgrades to your system. Or a Zu Bok, for a less exp... 
How Much Does Damage Affect Value?
Enjoy your music! =8^) 
How Much Does Damage Affect Value?
Bummer the part isn't available. I agree with most of what's been posted(outside of the smart a$$). But one factor hasn't been addressed: How much do you like the unit's sound/presentation? Can you bear the cosmetic flaw, to enjoy the amp? What's ... 
New caps for preamp?
OOPS- I re-read my previous post, and should have said the ARC would already have excellent Wonder Caps in the signal path. Anyway- Welcome to the world of upgrading(maybe). 
How Much Does Damage Affect Value?
That sounds like the logical and fair course of action, given the inadequate packing. 
What is the affect of cd player?
There is no "most important" in an audio chain. Think of yourself as looking at a garden(your recording of musicians in the original venue), through a number of glass panes(source to ears/your electronics and room). Does it matter which panes of g... 
12AX7A and AT7 tubes
No small signal tube, that is currently manufactured(outside of EAT Cool Valves) can provide the sound stage/timbre/overall music reproduction of a strong, quality(ie: Mullard/Brimar/Amperex/Telefunken/Siemens)NOS valve(pre 70's). If you enjoy the... 
To turn off or not to turn off
"SS equipment idles at very low power and need not to be turned off unless there's threats from power surges." UNLESS that SS gear happens to run in Class A. 
New caps for preamp?
A lot depends on the make of your pre-amp. If it happened to be an ARC for instance; the unit would already have excellent MIT caps in the signal path. But- If you were to replace the power supply's electrolytic caps with Black Gates(there are sti... 
Putting vintage tubes in the power supply of pre
Just a suggestion: try a NOS Mullard 5AR4/GZ34 from the Blackburn plant, in the rectifier slot first, and listen for improvements. Then find a NOS TungSol 6SL7GT/VT229 Round Plate(from the 40's). There are a lot of good NOS 6V6 power tubes that wi...
