Wire the House A/C or get Power Conditioner?
I bought a brand new, American made, 250' spool of 10/2 Romex off eBay, for $75.00(shipped). That was about one third the price locally. It's YOUR aural satisfaction that's important, not your electrician's happiness! Use 10 AWG for your dedicated... 
Wire the House A/C or get Power Conditioner?
Keep the runs separated by about six inches, over their total length, to avoid any induction. 
Wire the House A/C or get Power Conditioner?
You should do both, but follow the path that Rushton suggests. Been there, done that and wish I'd done the double run of 10AWG & high grade outlets first. And an emphatic YES; high quality power cords are part of the equation also. I'm using a... 
Rectifier Tube Clarification/Help W/ Dared 2000a
From personal experience(and many agree): The Mullard/Blackburn GZ34 provides some of the best sound and longevity, of any NOS rectifier. 
6SN7 tubes
Some further 6sn7 family info: (http://home.att.net/~chimeraone/6sn7sound.html) That your equipment has those higher voltage tubes installed, does not necessarily indicate that the piece is operating at higher voltages. DO contact the builder, and... 
Cary rocket 88 vs dynaco st70
Dave- Like I said: I've owned both amps, and the last ST-70, from stock to rod-rodded(16 years). You won't miss your ST-70, once you've tried the Rocket 88 in triode mode(especially with some NOS inverter/driver tubes). 
Cary rocket 88 vs dynaco st70
Calbrs03- The two first ones are power supply filter caps. The other is a resistor. 
Cary rocket 88 vs dynaco st70
A bad power supply filter cap(in any electronic component) can cause a variety of noises. Could that be what you're thinking of? 
Microscope for stylus inspection
Dweller- The seller of that album may not have ever cleaned it before playing. Grooves that are worn by styli actually sound more muted than when new, as they've been, more or less, "shaven." Dirt that has been melted into the vinyl by stylus pres... 
Cary rocket 88 vs dynaco st70
Output capacitors? What are those? I've owned both amps. Had no noise from either, at all. Over the years I had upgraded the coupling caps, multi-section cap(which could be your issue), and added some capacitance to the B+ supply(plus a few other ... 
Why Rhodium?
Willoamp- Read this: (http://www.corrosion-doctors.org/MatSelect/corrgold.htm) Especially the first line, which states that gold is the most NON-REACTIVE of ALL metals. 
Help: Tube roll for Cary 120S
Here's Upscale Audio's process for tube testing, burning and matching. Kevin even has a 90 day warranty on his tubes. The customer service is hard to beat, and should a tube fail, down the road say a year or two, he can provide a tube that matches... 
Amplifer Wattage Question
Here are a couple a simple-to-built LED audio output meter schematics. Easily fast enough to register peaks. They're limited to 10 power levels, and won't give you fine measurements though. (http://freecircuitdiagram.com/2008/09/13/audio-power-met... 
Why Rhodium?
Some may consider Rhodium an, "excellent" conductor of electricity, but- to what are they comparing it? Silver's conductivity is 106, Gold's- 65 and platinum is 15 on the Electrical Conductivity chart(copper is considered the reference at 100). Rh...
