Самодельные газоразрядные трубки, без штенгелей, запайка электрода в разреженном воздухе
При такой запайке стекло почему-то получалось с пузырями, словно из платинита что-то испарялось - при запайке при атмосферном давлении такого не происходило окромя одного ввода, который в штатном своем месте расположения (в лампе накаливания в прошлом) был отчасти впаян плохо. И заодно платини почистился при запайке так, что видно по цвету чистой такой не окисленной меди.
