New SPICE Models for Vacuum Tubes


Intusoft announces a new SPICE library with over 40 sophisticated
vacuum tube models using a subcircuit topology newly published in
Intusoft's SPICE Newsletter.  The vacuum tubes models have all been
characterized in a laboratory environment using actual devices.  The
library comes with a number of circuit examples including regulated
power supplies, preamps (RIAA), amplifiers (Williamson #1 & Mullard)
and vacuum tube test circuits.  The library also includes generic
versions of the triodes, pentodes, and heater models published in the
Intusoft Newsletter, allowing users to input their own model
parameters.  The models may be used with Intusoft's Berkeley SPICE 3
compatible simulator to simulate RF and audio tube circuits.  In
addition, a tube modeling service for models not included in the
library is available.  Please contact Intusoft or Intusoft's
distributor in France, Excem (Tel.  1-34-75-1365, Fax 1-34-75-1366),
for more information and pricing.
