This is the amplifier.

If anybody can help me where can i find those models I'd appreciate it very much.

Many thanks in advance.

Jesus.

The BD140 is easy

.MODEL BD140 PNP (IS=1e-09 BF=650.842 NF=0.85 VAF=10 IKF=0.0950125 ISE=1e-08 NE=1.54571 BR=56.177 NR=1.5 VAR=2.11267 IKR=0.950125 ISC=1e-08 NC=3.58527 RB=41.7566 IRB=0.1 RBM=0.108893 RE=0.000347052 RC=1.32566 XTB=19.5239 XTI=1 EG=1.05 CJE=1e-11 VJE=0.75 MJE=0.33 TF=1e-09 XTF=1 VTF=10 ITF=0.01 CJC=1e-11 VJC=0.75 MJC=0.33 XCJC=0.9 FC=0.5 CJS=0 VJS=0.75 MJS=0.5 TR=1e-07 PTF=0 KF=0 AF=1)

The 2SC5359 is not so easy. According to a datasheet I found it is/was made by Toshiba but a part number search on their website did not turn up any SPICE model.

If you substitute it with 2SC5200 your simulation should be OK

.MODEL 2SC5200 NPN (IS=3.0463E-11 BF=96.20 VAF=100 IKF=15.04256 ISE=5.6190E-11 NE=2.0 BR=4.849 IKR=1.05012 VAR=100 ISC=7.18E-8 NC=1.5 RE=0.0025 RB=20.18 RBM=0.0014 IRB=1.0E-7 RC=0.01137 CJE=4.5000E-10 CJC=8.4915E-10 VJC=0.68977 MJC=0.54081 TF=6.8583E-10 XTF=9.5721 VTF=10.425 ITF=6.8697E-2 TR=1.000E-8 XTB=1.45 EG=0.82 FC=0.5)

Also use the 2SA1943 instead of 2SA1987

.MODEL 2SA1943 PNP (IS=1.30E-10 BF=91.42 VAF=100 IKF=4.480 ISE=1.02E-10 NE=2.0 VAR=100 ISC=5.0900E-9 NC=1.5 BR=0.882 IKR=2.9015 RE=0.0011 RC=0.0553 RB=140.05 RBM=0.0041 IRB=8.5e-9 CJE=2.00E-10 FC=0.5 CJC=9.45E-10 VJC=0.48 MJC=0.28 TF=9.250E-10 XTF=10 VTF=10 ITF=1 TR=1.00E-8 EG=0.76 XTB=2.68)

BTW, I wonder if that circuit has ever been built by anybody. By the style of the drawing my guess is that it was originally published by Elektor.
