LF coulped transformer class A amplifier

[maria_m]

Hi guys. Thanks for your time. I need help with BJT with transformer circuit. I used the osciloscope to observe the wave on the colector side of amplifier but I find it's not accord with the theory. I can't find a problem. I tried with TS_VIRTUAL and 1P1S transformer. I changed the parametars of transformers like turns ratio, R on the secondary etc., but I didnt see  change of wave on the osciloloscope.  Maybe I used wrong transformer. Audio power od transformer is 10W. I use Multisim 14.1.. Sorry for my english.

Hello!

Could you attach the file or a screenshot of the circuit you have in Multisim? Also, give us more context on the wave you expected to see on the oscilloscope.

Hi. Sorry for waiting. I need to take the parameters of this transformer to get 10 Watti at a frequency of 1 khz and simulate. Turns ratio is 17.69:1. I dont know which transformer I should take in this case. Thank you very very much.

Please attach your schematic.  The transformer in multisim is close to ideal, so it should work fine.  Something else in your circuit is probably wrong.
