https://antreas555.webs.com/socketsrfparts.htmI used to know this guy, he wasn't an active amateur but he was always selling items in the ham fests and he kept beside this webpage.
Now he is SK and his wife tries to sell what is left.
In greeknglish (english letters with greek meaning) is written that anything is described with brown letters is sold out. The items that are described with yellow or white letters are the only available.
Thank you for searching in the net in order to help me find the sockets. I appreciate it.
