Update: I need help
Since this gig started a week ago the money is already being held by fiverr. The money will be given to the seller in 3 days if I don't dispute and win for this shit design. We are in the second stages because I did dispute based on what you guys were saying. And that worked. This idiot "revised" his circuit. Now I need to know if there is any reason I should be paying for this or if you guys can find flaws that can downright destroy this whole deal.
LTspice file attached below
Here is the new schematic
Comments I have so far, "3055 will not function at 1 MHz. Its gain-bandwidth product is 2.5 MHz, and it needs to provide a current gain of at least 20, which it can not." , "the first time the amplifier output goes below GND, D4 will burn up"
I should also note the goal of this was a 140watt amplifier for 500khz-1Mhz.
You guys were great. Hope you don't mind me pinging you. I have some serious thanks after this. @jpanhalt , @OBW0549 , @AlbertHall , @MrAl , @Sensacell , @AnalogKid

Hi,
This amp is 140 watts between 500khz and 1Mhz for my signal gen. I paid this person on fiverr and am wondering if this thing is any good before I accept the delivery
UPDATE: My fiver guy said Q5 is supposed to be a 2N3019 like Q3. Thanks to @bertus for pointing that out
