This is a fully working unit, with No hum at all and very good S/N. The unit consists a headphone amplifier ( per Andrea Ciuffoli design ) and a linestage
amplifier ( which using the same input stage as headphone amp but with solid state output stage.) The preamp sound is very warm in nature. The chassis
is made by three pcs of solid rubber wood ( 20mm x 3) clamped together ( 12 inch x 9 inch), rock solid and 3 wooden spike beneath it for very stable mounting. The amp come with a separate power supply. Power supply module weight about 5KG, amp itself weight about 4KG. There will be one NOS Voskod 6H23P ( 6922/ 6DJ8)
and one US made GE 6080 tubes attached. Quality parts inside, ALPS Japan volume pot, Philips BC electrolitic caps , Vishay resistors, MKP polypropelene coupling caps..The amp sounds good and you will be amazed with it's preamp ability as well. Thanks
