I received the Wangs VT-1H amp today, WOW! Sounded good with stock china tubes, but I swapped JJ and Tung-Sol tubes. I noticed output volume dropped lower with the JJ tube, but I left it in. Stock tubes were not that bad sounding. The output transformer is marked with output impedance, how cool is that!
This is the bottom view of VT-1H PCB
Output transformer for VT-1H. 10K ohm impedance to each plate for push pull operation. 8 ohm output, which works with 8/16 ohm speaker cabinet
