If it only has primary and secondary windings (no driver windings), you could pull a transformer out of a small (low power) junker amp and install it in this amp, to confirm that the problem is the transformer.
If the transformer is defective, you will have to rewind it. Count the turns accurately when removing the original windings.

Before I pull the transformer and start unwinding it .
Is there anything else I should check ?
Like drive wave forms ect ?
When I load the locations with fets the amp will draw excessive current as soon as the remote wire is applied .
Would it most likely be the transformer or could it be the inductor as well ?

After examining the winding that you pulled off, what convinced you that the transformer was defective?
Is there anything else I should check before pulling the transformer again ?
Instead of a 0.1 uf cap can I use a 1000pf cap to to see the actual square wave for the fets ?
To rule out a driver issue

I have been using a 0.1 if cap on other amps along with this amp and the wave form is what I get on a previous post .
So I guess I will be pulling the transformer and unwinding it to see if I can find if there is a short since twisting it doesn’t change anything

Virtually 100% of the time, it's best to find the short when the transformer is in the board. Push, pull, lift, twist... When you pull it and the short miraculously clears, expect it to boomerang. If ALL else fails pull it.
I rewound the transformer I didn’t see any shorts on it at all .
Do I load a fet in each bank to see if it still draws excessive current ?

You load the FET locations with no FETs in the PS.
Did you re-wind ALL of the windings, primary, secondary, driver...?

Did you check ALL locations?
Do you have another transformer that you can drop into the amp?
It doesn't need to be close. Even just soldering in the primary windings may help you to track down the problem.

Never mind .
I found a broken solder connection .
I appreciate all the help with this amp
Thanks Perry
