Question B1 buffer maintenance

Hello, I stupidly burned the jfets of my B1 buffer
(Reverse polarity on a lead-acid battery)
Is the LSK170 quad grade B a good choice?

The documentation states that Idss should be between 5 and 10 milliamperes.
... and Grade B Idss ranging from 6.0-12.0mA
Is this however OK
Thank you

I reckon it would be. Grade B or BL for the original Toshiba JFETs, is generally the preferred kit.

Hi, thank you for your advice ;
I will probably buy the original kit at 'Pass DIY' to take advantage of the Toshiba JFETs NOS ...
... even if the shipping costs are horribly expensive !!
I really love the sound and neutrality of this device
