You're .SUBCKT line is longer: .SUBCKT 12AT7 1 2 3 + PARAMS: MU=60 EX=1.35 KG1=460 KP=300 KVB=300 RGI=2000 + CCG=2.3P CGP=2.2P CCP=1.0P The lines beginning with '+' are part of the subcircuit definition. These are parameters of the subcircuit. ngspice can not simulate such subcircuits by default. You have to build ngspice with the configuration option --enable-numparam.
