Just received one pair of grid chokes, AMCC 8 amorphous C-core, 1700H/8kOhms/15mA, 6x5,5x4 cm specifications. Manufacturer is AE-Europe from Netherlands, they had one pair in stock and I got them in a week. Chokes don`t have "legs" or similar way to fix them to chasis, must invent something...
The nice factory price of 60 Euros (~$71) per pair exactly was doubled at the end, by addition of various taxes, postages and bank provisions...
Listening test coming (not so) soon...
