Query: Sherwood RX-4109 105 Watt Stereo Receiver

I bought this Sherwood to replace a 1970's era Radio Shack AM/FM stereo tuner that did yeomen service over the years. Receiver arrived in a timely manner and is perfect for my needs. Fairly simple controls that even this senior citizen can easily use, I'm quite satisfied with this purchase.
