MELODY SWH-1688II, This is the MK 2 version in perfect condition. 9 of 10 only due to age. Has four switched inputs and four outputs. The tube compliment of the SWH1688II consists of two 101D tubes for voltage stabilization, two 6SN7 & two 6SL7 tubes for signal amplification, and one 5AR4 for rectification of the DC power supply. The attenuator for the volume control is a 24 position stepped attenuator with gold plated contacts and individually soldered resistors. It has a nice rotary on/off switch and the build quality is like a tank with a gloss black finish. No skimping there!!! This a serious preamp. Asking 2100- obo...
