Mosfet substitute questions

[Jazz P Bass]

Thanks guys. The FQP13N10L I mentioned in the first post are my cheapest option due to shipping to my locale.
I was hoping to get some input on the Vgs clamps I asked about so I could include any zeners in the part order that I need to put in this afternoon.

I was under the impression that the 'internal' zeners where for handling issues.

The newer mosfet designs worked around the susceptibility of frying the junction by simply touching the pins.

Yes, getting some extras and matching was the plan.
Base voltages at bi-polars were in keeping with currents, from memory approx. .55V for the ones idling lower current, and approx. .6V for the ones idling hotter.
Again, voltages and idle currents followed the Fet's when I switched them around.

Itīs weird because I canīt imagine a mechanism for that to happen just out of the top of my head.
Oh well.

The best replacements are the IRF530, IRF530A, IRF530N and the RFP10N12.
