Hi Zaikesman, Yes, At Marcof electronics, we used to pull the bottom and dampen the motor also for resonance transfer to the platter. We made our own mat called a glasmat and we glued it to the platter. Our putty as I called it was made for us and... 
Review: Technics SL-1200Mk2 Turntable
Since a few have commented on this ancient thread, I might as well chime in. I haven't seen a 1200 in years, but way back when, I have modded several... Here are a few easy mods that made a noticable differnce. Use acoustical dampening putty aroun... 
moding and the inexperienced
I completely agree with all the above 95%... Any Adcom other than the GFP750 will never be made significantly better to the point of being worth the money for future resale... On the other hand. If you have some nice parts laying around and in gen... 
Is Bass Non-Directional In A Two-Channel Rig?
Thanks Tom, As you might expect, I've got quite a stash of Marcof innerconnects, I also use our speaker cable. We experimented greatly with litz, different braids, wire guage etc. I am using some that we never manufactured, but they are closer to ... 
Is Bass Non-Directional In A Two-Channel Rig?
08-15-11: Theaudiotweak"You can hear where the bass originates even below 40 hz".Well maybe if crossed at 40HZ @ 6 db per octave, maybe, but crossed @ 12, 18 or 24 db per octave. I wish that I could quote some test somewhere, but I have had hundre... 
Is Bass Non-Directional In A Two-Channel Rig?
Mitch4t, Sorry, I just realized that I did not completely answer your question... Also yes, you can put a sub behind you. Back at Marcof Electronics seems like 300 years ago, we had our own sub design. We buit an 8, 10, 12 & 15 inch model.. At... 
Is Bass Non-Directional In A Two-Channel Rig?
The basic anwser is yes, bass is non directional in an any channel rig, but at different frequencies for different people. Some people start loosing the ability to discern where bass comes from as high as 120hz, by the time you get to 80 hz, no on...

Cat damaged speaker, Help
Hi Rodmann 99999, Glue and fabric won't add a half gram of mass and it is not on the cone. Final qts won't change by .01. This mass will not be noticeable. I agree with your last post, but Bob doesn't need an "o"ring. 25 or 30 years ago, I did rec... 
Cat damaged speaker, Help
Bob, I started to send you a private email but decided to go ahead and post this here for everyone. The best repair is one that will be permanent without adding mass to your cone. Much mass will change your qms. Although I doubt this minimal mass ...

Sorry, I just looked at this thread. I have repaired hundreds of speakers, here is a quick fix. Remove the woofer. Cut a piece of thin fabric to fit in the surround area and cover the slit from the rear of the woofer. Now find some old paint. Care... 
Do you understand your amplifier?
