Could use your advice re: tube gear
Yes, you can't store **any** amplifier for years (long enough for surrounds to perish) and expect it to sound right after that. The filter caps die if they don't have voltage applied to them occasionally.If you want tubes to sound right- play bass... 
Low Amplifier Loads / frequency range
It depends on the speaker design. see:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpIf you are designing for tubes, keep the load easy (or 16 ohms) and you will do very well with no need to biamplify.Its a huge myth that yo... 
Would Atmasphere M1 work with ML Ascent i speakers
I've not tried the combo and have not heard from anyone who has. However, looking at the specs you **may** have to use a set of ZEROs (http://www.zeroimpedance.com)to make it work as Martin Logans tend to have very low impedances at high frequenci... 
Tubes vs Solid State
Matching amps and speakers is important!Take a look at this link:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpThe B&W 802 is designed to work on an amplifier that can double its power when the load is cut in half. Spec... 
Oil For Nottingham Spacedeck?
Generally with any turntable platter bearing(s) you can use a few drops of Dextron automatic transmission fluid with no worries! 
Empire 498
We can service a lot of that stuff- we even got the correct motor mounts re-manufactured. 
Lazarus cascade classic and Mark III amp's
The Lazurus was based on the 'Last PAS' construction article published in what was back then called Audio Amateur in the late 1970s or early 1980s.The Mark 3 (I assume Dynaco) you can find by Googling images of the schematic. 
Could use your advice re: tube gear
If your amps were in storage, its likely they are not working up to snuff. The Marantz was a nice amp but unless its been rebuilt/serviced recently I would not expect it to sound right- in fact I would be nervous about plugging it into the wall!A ... 
what is an ideal tube amp
Charles1dad, take a look at this article, it will help in understanding my explanation that follows:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpFour ohms came in with the transistor- we all know that. However, along with ... 
Good amp match for vinatge Vandersteen 2C's?
The first time I heard the 2C was with a very early set of our amps. They were revealing and musical- no troubles making bass either. We did several shows with Vandersteen speakers, using our smaller amps. One time Richard came into our room to ch... 
what is an ideal tube amp
If a tube amp with an output transformer has a 16 ohm tap, it will have slightly more power and certainly less distortion when driving 16 ohms. This is because the output transformer is more efficient. In fact it will also exhibit more bandwidth- ... 
what is an ideal tube amp
John also has an Atma-Sphere setup, with a fairly well-optioned MP-1. He has had Atma-Sphere amps since 1989 if memory serves.I bought a set of T-3s in 1998. There has been no looking back. They have been updated with the dual woofers, new crossov... 
Plinth mass vs. Foundation mass
The coupling between the platter and the tonearm must be exact. If the platter is moving with respect to the arm, the cartridge will interpret that as a signal and a coloration is thus introduced.Thus the plinth should be utterly rigid and devoid ... 
Headshell Washers : Nylon or Stainless Steel?
Moonglum, titanium washers get used by high end bicycles all the time.http://www.nylonalloys.co.uk/cgi-bin/shop/nylon-alloys-categories.pl?TITANIUM|METRIC| 
Ground Cheater plug or....
Al is correct. This will not be solved by cheating the ground. Grimace, you've not mentioned your speakers; if they have an efficiency of over 100db or if your room is really really quiet this might be perfectly normal.
