Hmm yet another version of the RR 9 model. I haven't seen that one before.
BTW the reference to 1450 watts is not the microwave output wattage . These old Amanas are what 800 watts..mines still in storage so I can't go look. Don't know where I'm gonna put mine in the new house..our other house had the perfect setup for two full size mw's but the new one doesn't. My partner doesn't like my old RR and prefers our old GE so he won't use it.
Pete, that's an RR-8; a tough model to find at that. Not only will it bring to temp and hold, but the power is variable from 0 to 100%. Not to be confused with an 8T, that's a different beast entirely.
