Yes - I know that this is not directly Dynaco tube related but I thought that forum readers looking for real good FMHD tuner for not a whole lot of money might want to know
One of the nicest tuner value out there right now is the Sony XDR-F1HD tuner that is available online for just about $90 USD. I bought one because, although I live about 70 miles from Boston, I am down in a valley area. Even with an FM antenna in the attic I had trouble pulling in the Boston stations. This new Sony is the most sensitive FM tuner ever made - bar none. It also pulls in the new FM HD stations if there are some in your area. The "HD" afer the FM does not mean high definition, it means "hybrid digital". I have tried numerous high quality tuners here including two of the best tuners ever made - A 6 gang Kenwood KT-8300 and a Yamaha T-85. This little Sony (and I say little because the tuner only measures 7 inches wide by 6 inches deep) is way more sensitive than either of the two. The Sony uses a sophisticated noise reduction system and adaptive IF filtering that increases signal to noise ratio and keep distortion levels low. One comprehensive review of this tuner is at the link below.
