I checked out the SND tube sales site the other day & discovered thatThe 570 is a very rare item even here in the US. A friend of mine had one and
sold it to a collector for a quite high price. You can see that very unit on
the cover of Alan Douglas's "Tube Testers and Classic Electronic Test Gear".
According to the book, only about 1000 were made over a period of ten years,
starting in 1956.
