Flat Head 554 Tube Buffer Amp

............ This is a product that I have been successfully selling for some time now. It is a handcrafted Tube Buffer Amp that I call the 'Flat Head 554'. In this version, I have gone the extra mile by using two different transformers in the power supply. The first transformer is only used for the audio circuit, and the second transformer is used only for the tube filaments.... I use Obliggato output film capacitors, bypassed with polysterene film capacitors. There is a two position switch on the heavy duty power supply that allows the heaters to be turned on first thereby allowing the tubes be preheated before operation.... The audio circuit itself uses a set of Genelex 6922 triode tubes. I have found these to be a great match for many ears. It should be also noted that this model has two inputs that are switchable on the rear panel.   As always, questions are welcome.
