Pioneer SM-Q300
|
This is classic Pioneer SM-Q300 Stereo receiver from either the late 50's, or early 60's. Although it a stereo receiver, there is no built in FM Multiplex so the FM is actually monaural. The receiver does contain a output jack and a switch to add an optional multiplex adapter. On this set, FM is on the right channel and the AM/SW bands are on the left. The idea was that a radio station would simulcast it's program on the AM band and on the FM band, and you would tune the AM and FM to the same station broadcast and receive your signal in 'stereo'. Considering the quality of AM reception to FM, this doesn't seem like a good idea! I guess that's why it's not around anymore. This is a high quality receiver employing 19 tubes and 20 watts per channel. It's also very heavy.The audio output is a push-pull design using the 6BQ5 tube. This set has a very unique stereo tuning eye tube in the middle of the dial. The tube display is divided into a right and left side and each side works independantly of the other. Very unique, and I have never seen this tube anywhere. Fortunately, it is in good shape and works very well. The set sounds very good, but not quite as good as my Dynaco ST-70.
