Partridge transformers have been apparently available on an
intermittent basis in recent years but like yourself a subset of Brit
vendors are "right ****s" so us arrogant colonials just don't want to
**** with them anymore. Partridge can't be too anxious to sell their
wares as they don't advertise, not here and not there either-we get UK
magazines easily at news vendors even in backward markets in North
America.

Japanese, German, and even Italian publications would be more
valuable, but tech pubs in foreign languages are scarce.
