Ya got a nice little Sherwood there.
I got some of these for friends on a budget in the early 70's and most are still running. I liked to pair them up with AR 4's and managed to get some pretty decent sound from that setup. Not necessarially loud, but nice... very nice.
As for the speakers, they did not come with the unit. They appear to be some off brand, perhaps part of an inexpensive three piece unit of the time.
They aren't anything to write home about. If they work, fine, but I wouldn't invest any time or money in 'em.
