The input is 8 Vp-p and 100Hz and reached to output of 1800 Vp-p and 100Hz.
The publisher mentioned he used the following parts to build it:
OP07 , LM356, MTP2P50E and BUK456800B.
In the multisim database, I couldn't find these exact parts (perhaps because companies stopped creating them). So, instead I used the following parts for the following simulation:
OP07, LF356H, MTP2P50EG and NDD03N80Z-1G.
And I can't figure out whats the problem with the design I implanted on the multisim, as I don't get the high voltage that is desired.
Thank you for anyone who reads this and tries to help me, much appriciated !
