At voltage, at what current, and at what frequency do you test this? What was the load in terms of R/L/C? Did you swap a different transistor and see much better behavior? If so, what was that transistor?
This is the kind of test that I could replicate and capture screen shots.
Replaced output signal generator. Checked scope. Replaced with 2sc1220a big difference
HI
Someone has already used the TTA004B model given by toshiba ?
TTA004B | Transistors bipolaires | Toshiba Electronic Devices & Storage Corporation | Europe (EMEA)
it's just unitilizable in a simple circuit
HFE 488 for "pspice model" and 2m for "ltspice model"
164 for the 2SA1381 cordel model in the same situation

I used in my preamplifier power supply. LtSpice showed the gain about 210, and it was approx. 230 in real life. The current was 10mA.

I tested the TTC004 in JLH69 as a VAS transistor, and it wasn't good, it had a blurry sound. As a driver I don't know what it is, I plan to test it in a Hiragi 20W which I'll be doing soon. I currently have a TTA004 and a TTC004 in a Walt Jung shunt regulator. Toshiba's model is good, it doesn't deviate much from the measurements.

in fact in my amp the TTA is good, but in a simple simulation like that i have strange results
Could you try in your ltspice ?
thanks
