I don’t know anything about that brand but it’s a cool little combo!!!
What’s the asking price for it???
If it wasn’t super expensive, worked, & sounds good I’d definitely grab it!!!
IMHO The ambiguity of these kinds of amplifiers is part of the appeal....
As to the country of origin the EZ81 rectifier kinda makes me think British vs Japan but who knows, perhaps it was made in South Africa using both European & American components?
