Linn LP 12 hum not coming from Bryton phono stage.
The siren rising in intensity is or was evidence of positive feedback, somewhere. Good that you put a stop to it as you might damage your amp and or speakers. 
2020 update : JC Verdier La Platine
I suspect you all are correct about the fact that the suspension of a vintage cartridge will have aged, inevitably. But does that really matter, when one is getting pleasure from the sound emanating from that cartridge? Why waste time perseveratin... 
Wall mounting on studs
It’s not such a terrible idea not to play them. In many cases the musicians and the music are both second rate.  
Vintage DD turntables. Are we living dangerously?
Dave, I noticed that you now have an L07D. Given your capabilities and your propensity for modification, have you considered changing the tone arm wires in your LO7D? I can’t prove it, but I think they are a kludge compared to the rest of the turn... 
Springs under turntable
Platter and top surface of plinth should both be level, or both should be on the same plane even if not perfectly level. Otherwise, you might have an issue with the tonearm mount not being on the same parallel plane with the platter, which would m... 
A question of bias for new tube set
How do you know the original tube with the low bias current was actually defective or aged really? Did you check the bias voltage on the grid of that tube? It could be a problem upstream, affecting grid voltage. In which case a new tube inserted i...

But of course. 
Is a captured good tonearm cable better than a high quality one DIN connection?
Tomic not tonic. 
Frequency response off with test record
Nothing to do with loading which affects treble region. Also given your vague description you might be looking at a benign bass rolloff. At what exact frequency? Is your scope calibrated? Are you accounting for the RIAA effect on frequencies below... 
Is a captured good tonearm cable better than a high quality one DIN connection?
Tonic, no. Sometimes fanaticism yields to convenience. However, if I ever owned a SUT, I would be sure it utilized flying leads between SUT and phono stage. 
Is a captured good tonearm cable better than a high quality one DIN connection?
It all boils down to my motto: the best connector is no connector. No matter how expensive a connector might be, no matter how elegant it may appear, and no matter what precious metal it is made of, you are better off getting rid of it.

I watched Herb Papier install the wire in myTriplanar. It’s a continuous run from cartridge to plugs. 
Does the 33 hertz frequency turn vinyl into super vinyl "YES"
+1 
IMHO (and friend's) opinion of acrylic platter
Vinyl spin, can you remove the OEM rubber mat and just plop the acrylic mat on the bare metal surface of the platter? If so , try that.With all respect, the 1019 is a fine vintage piece, but it was not meant for this sort of tweaking. It is simply... 
Is a captured good tonearm cable better than a high quality one DIN connection?
What exactly have you purchased, and what exactly do you propose to do? it sounds like you have purchased a triplanar with a continuous cable from the cartridge pins all the way to the inputs of a phono stage. If that is the case, then no it would...
