..Bi-n-tic soon finished!
just cant find: 2n2 styrene, 1k PT146 tempco...Where can I buy them?

and also: should I connect the short leg of the LED to LA in the Saw
Pitch Shifter/Wave Multiplier?..and where should I connect the other
longer leg of the LED?

and what would be the difference in between using ferrite bead to 10R
resistors?

Regards/Boward

not sure where you are, but mouser in the US has 2n2 polystyrenes:
part number:

23PW222 (these are radial type)
or
23PS222 (axial type)

i used the axial type in the past, but those seem to be sold out.

iirc, ferrite beads has very low resistance at dc, and has much more
resistance at high frequency. these are common. it should filter PSU
noise better than a resistor.

Elby Designs sells the Tempco and also a Bi-N-Tic filter special parts kit:

The 2n2 cap is Mouser 23PS222

You would not notice much difference with a 10R resistor. The bead
helps filter out RF. If your neighbor is a ham or a CB radio operator,
you might want beads.

Short leg is usually the cathode, so that would go to LK (Kathode) while the
long one goes to LA (Anode)

I can also include the 2200pF polystyrene to the kits if desired.

The ferrite would offer improved high-frequency suppression but the resistor will work perfect for most of us.
