dynaco st 70 what tubes to replace first
If the amp didn't come with a Mullard(Blackburn Plant) GZ34/5AR4 rectifier; get one(NOS). It will probably be the last one you'll ever have to buy for the unit. That and NOS 7199's(Philips ECG=best, or RCA black plate, Sylvania) will both make maj... 
Matching Replacement Woofers
Mr B- In the initial post, it sounded like the manufacturer of the speaker system was out of business. Then too: I doubt many would blame the company for abuse that the system suffered at the owner's hands, as most woofers are blown/damaged by bei... 
Matching Replacement Woofers
Mr T- Because Waldom is the only manufacturer of reconing parts, outside of the companies that distribute kits to their warranty stations(mostly just for pro drivers; ie: Gauss Cetec, JBL, EV, Altec, etc.). At least; that's the way it was when I h... 
Matching Replacement Woofers
Unfortunately- ALL reconers use Waldom Electronics parts with which to recone woofers(unless they are a warranty repair service for the driver in question). The chances of their using a voicecoil, spider and cone combination that would actually ma...

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?
