Inner groove "Rumble"
A la Casey's good idea, this speaks also to the question of whether you are hearing "rumble" or "hum". The power amp transformer could induce hum, not rumble. 
Question on FR 66s
Dear Dover, I am well aware that one can "twist" the cartridge in the headshell to obtain a non-standard offset angle. I suppose I should have acknowledged that possibility in my post to Henry. In fact, that's what one has to do, in order to use D... 
Inner groove "Rumble"
Dear Adam, I haven't a clue. Typical reasons for what you are hearing are that some cartridges can pick up EMI from some turntable motors. Thus, as the cartridge nears the center of the LP, it gets closer and closer to the motor until at some poin... 
Question on FR 66s
Dear Henry, I've got my answer. No worries. 
Best vintage or modern tonearms for Denon DP 80
For under $3000, the choice is VERY wide for excellent tonearms. There is almost nothing you cannot consider at that price or under, if you are willing to purchase second hand. Further, the tonearm is best mated to the cartridge, rather than to th... 
Who needs a MM cartridge type when we have MC?
Dentdog, FYI, Rhea is not balanced. Io is balanced. That's one of the major reasons for the far higher cost of the latter. This is not to say that the Rhea is not a fine sounding phono stage. I have noticed, however, that a lot of companies blow s... 
Question on FR 66s
Dear Henry, I am a bit puzzled about a recommendation for a specific headshell offset angle to go along with the recommended P2S distance and overhang for the 64S. In the case of headshell offset angle, isn't one "stuck" with the built-in angle? I... 
Inner groove "Rumble"
Marakantz, With much respect, your last statement is a doozy (not a Deusie). Can you say why that would be? Would you say that the converse is true: a new phono stage is less sensitive to rumble? I don't think so. But it does follow from your prem... 
Inner groove "Rumble"
Might help if you say what turntable, what tonearm, what cartridge. 
Retipping Service
I 3rd the notion that Sound Smith does great work. But I was also interested in the service mentioned by Viridian above (see URL). The website is unrevealing as to what this guy does, however. Viridian, do you know what choices of cantilever and s... 
Do 45 RPM records need higher anti-skate setting?
Omie, What do you research and what do you design? Inquiring minds want to know. 
Who needs a MM cartridge type when we have MC?
Has anyone got a "sedagive"? (See "Young Frankenstein" for reference.)These esoteric discussions of body parts have got my head in a tizzy, even with my medical background. 
Question on FR 66s
If I can find it, I will. I actually attached the post explaining my observation to a thread where the OP was talking about the question of having to twist the cartridge in the headshell, when he was using some other vintage Japanese tonearm with ... 
Question on FR 66s
Raul, When you have calmed down sufficiently, I would like to know what you think about my experience that suggests best sound is achieved when the cartridge is aligned according to the geometry for which the tonearm was designed. That means, for ... 
Do 45 RPM records need higher anti-skate setting?
Ralph, Re the original question, friction (between the stylus tip and the groove) is the prime source of the skating force, and friction is independent of velocity. It's as simple as that.The only difference between a 33 and a 45 might be if the t...
