Q107,207 what's better 2SK170 or J310 , going through DIY Audio thread again would be painfull, thanks

J113 with 1k resistors replacing the 3k3. While your doing the shunt put a pair of 33uf 50v organic polymer caps on the input from the psu board, ie right on the -0+ on the pcb

Thanks Simon
I have spare quad of 2SK170 but I'll order J113 instead

Yeh, save the 2sk170 for signal duties. They're wasted in the psu.

Yup 100%

One more q , 10uF inductor for Calvins why not to use fixed inductor fromt the Mouser or elsewhere ?

[sq225917]

You could use any air core you desired. I roll my own at 8uH, works fine, rock solid stability. They do need to be air cored though.

Nice , what diam . of core and wire , no. of turns?
