Marantz 2250 Stereophonic Receiver (1975-77)
The 2250B is increasingly popular with Marantz collectors and has a massive amounts of wattage rated at 50 watts but if measured it will be closer to 70 watts!!
The FM tuner is very sensitive, the low distortion preamp is very good and Marantz used two direct coupled power amplifiers as well. 
Overall the 2250B is a very well built and good performing receiver. 
In general it is a little more expensive than the 2250 but ebay prices vary from $499,- to $1299 (depending also from recapping and condition) and increasing over the years, 
listed as solid investment and a ever lasting beauty both in sound and looks!
The Marantz model 2250 is an all solid state receiver incorporating the innovative design and unparalleled technology that have made Marantz famous in the audio component industry.
The 2250 features a sensitive FM tuner, a highly selective AM tuner, a low distortion preamplifier and two direct coupled power amplifiers on a single chassis, 
while retaining a flexibility comparable to that achieved using separate components.

This is the 2250B which was introduced by Marantz in 1976 and was really only on the market for about a year. Still, it is a very good mid-range Marantz receiver. I say mid-range because it's rated at 50 watts per channel but many will attest to the fact that it is under rated and is perhaps closer to 70 watts per channel when fully restored and recapped.
On some of the Marantz receivers the "B" designation indicates Dolby but with the 2250's it's more of an upgrade designation.  The Marantz 2250 is known for problems with its power switch as well as relay failure. It appears as though Marantz remedied these problems in the 2250B with a better designed switch and relay as well as better capacitors.
