I believe some equipment manufacturers put a cap or sometimes a high ohm-age resistor connected from the neutral to the chassis
I haven’t seen every piece of equipment but this should not be the case for many decades. There is however often a resistor/cap between the signal ground and chassis ground, which often leads to endless fun tracking down ground loops. The resistor doesn’t cause ground loops, the ground connection, resistor or not, in the signal causes it. A place where transformer coupled inputs really shine. :)
The classic linear power supply I’m familiar with has no reason to connect the neutral to anything but the transformer primary winding but they often usually connect the center tap of the secondary to chassis ground, which is of course also often connected to the EGC. Some equipment I’ve seen does the right thing by avoiding the EGC altogether and being "double insulated." Luxman integrateds are like this, which is brilliant from a noise point of view but given what I’ve seen I’m not sure how their amps are double insulated.
