This particular one seems to have had its logo repositioned (the original position in the upper left corner of the grille can be seen in another picture below). What's very interesting about it is that it's also labeled as a 20A model on the back. This must be a mistake right? I can't say for certain if 132A and 20A models are somehow related, but on this particular one, it looks like they could be. Or maybe this is just a case of a misplaced label on the back of the unit. Some google searching resulted in finding out that the 20A model was a 10 watt practice amplifier with a solid state design and an 8'' speaker. It was manufactured by Marlboro Soundworks in the US in the early 1980's. And for the 132A, i found some sites which stated the amplifier is in fact 30 watt. A user from ebay that i got in contact with, also told me that the speaker was 10'' in diameter. Another internet page states the 132A model was made from 1981 until 1984.
On the front panel, there are controls for reverb level (Reverb has the option of control via an external footswitch which is also pretty interesting), preamp gain, followed by equalizer knobs for bass, midrange and treble and a master volume knob. Like many other Marlboro amplifiers it also has two inputs, low and high, to connect your various instruments.
Here are some more pictures of the amp:
