Well, while I get the original diodes, I tested with two UF3003, which I think are similar .....
When connected, and take a few seconds, the LED is red, and have burned three MOSFET, a channel.
I can? Replace, BUZ11, by IRF 540N, or not a good idea?
Can I have burned those mosfet, because of the UF3003 diodes?

The N version of the 540 may not be a good choice but the non-N version will work for the outputs.
The UF3003 shouldn't cause any problems for testing. They may work as a permanent replacement. Make sure that they don't run too hot.
Did you reduce the bias setting before testing?

I replaced the mosfet burned for four IRF540
Bias adjustment was too high (almost 3/4 of the way), could have been the cause of the destruction of the three mosfet? (Along with two diodes, "intruders" ...)
Now, I've adjusted to a little less than half, and ..... the amplifier, works great!
Another repair more successfully completed! large, Perry! thank you!
