No Lewm, I was talking about measuring the record. I built my own adjustible bias supplies. I maintain a pretty dry environment and can push the panels a bit harder than the stock bias supplies. The only parts I kept are the two power transformers. I have the probe to make sure the bias supplies are putting out exactly the same voltage. I measure between power supply ground and the bias supply output with the panels connected. They are old Acoustat 2+2s which I have had from new. They spend a few years in another friends system while I played around with Apogee Divas. I got them back after I sold the Divas. I also removed the stock interface and replaced it with a 100 to 1 Sowter Transformer. They are driven with JC 1's. I cross to 4 subwoofers which I built at 125 Hz.
I have a better subwoofer design in my head which I will probably make next Winter. They will use a total of 8 Morel 12" drivers in a balanced force configuration. I also plan on getting a pair of 845's in the hopefully not too distant future. The 2+2s are wonderful but selfish. The treble rolls off quickly off axis.
An old trash record is on the turntable spinning now with the dust cover up. We shall see if it developes a charge. Afterwards I am going to play the record without the sweep arm to see what happens. As you probably have noticed there are opinions all over the place as to what does and doen't create static on records. I have read that Shure paper many times. Overall I prefer Antin's article. I would like to get this settled once and for all:)
