This is a smaller solenoid but came from a Teac A3440, it appears that they made a smaller motor change and at the same time reduced the size of the solenoid, its noted that on the mounting bracket they had two sets of holes so it was a planned change.
12 volts 10 ohms 1.2 amps
I have now seen these in the A3340S for certain
