About 2 years ago I made a post here about the Chinese VAA-70 MKII amplifier. Read at the previous link about the VAA-70 MKII. The Chinese also put out a "Goldox" ST-70 amplifier (seen above) in KIT form during the 1990's. Evidently neither of these Dynaco ST-70 clones took hold and both amps sold in very few numbers. The Goldox used a 12AX7 voltage amplifier stage for both channels and a 6SN7 for the phase splitter/inverter stage for each channel. The Goldox had a much more modern driver circuit than the VAA-70 MKII. Now and then I see one or the other show up on Ebay but in general both of these Dynaco ST-70 Chinese knock offs are pretty rare.
