Just tested the LZ1AQ amp with BFU590QX.? Performance equivalent to the 2SC5551. As with the 2SC3357, the max voltages are lower for the BFU590 than for the 2SC5551. However, just like with the 2SC5551, the voltages in the LZ1AQ circuit have plenty of margin.

?

Both Mouser and DigiKey have the BFU590QX in stock.
