RE: LCR Phono

There is an additional resistor in the first unit. I find it interesting that leaving out a resistor actually improves response. I believe the origin of the linked sketch was Hiraga and at the time of publication the only game in town was the Tango EQ-600P and various historical units (pultec)

The type of coupling allowed has nothing to do with the version used but the overall circuit design and the requirements on parts selection. Use 630V caps in #1 or #2 and you could direct couple up to that voltage. The diagram of #3 can also be direct coupled but I doubt the tango would be happy in that situation.
