? Melting solder from pins 1 and 5 is common on the 3k-A and 2k-4, both
of which use air system sockets. Melting solder from pins 1 and 5 in a
SB-220 is virtually unheard of provided that the fan bearings are oiled
every two years. // Why does the Eimac heat dissipating anode
connector have the fins going the wrong direction for Eimac air system
sockets?
