Current regulator Diodes please help

[grahamfocal]

I am desperately after the following current reg diodes to complete my AMB headphone amp. I can get them from Mouser, but the postage for such a small item is huge!!

I need:

1N5306 or 1N5307 X 2
1N5313 or 1N5314 X 1

any help with either where I can get them for cheap or if anyone have any please.

Some of these were listed in a post in our swap meet forum on july 12 - 2010.


For sale : Constant Current Diode 1N5314, 100V, 4.7mA

thanks for that, have not heard anything yet, so in the meantime anyone got any spares......pretty please.......

What is the current that these are providing?

There may be other types that can do a similar job, that is close enough to enable the circuit to work.

A jFET wired g-s acts as a current regulating diode. Adding a low value resistor to the source lead makes it's output current adjustable, downwards.
I have matched pairs of ~3mA current diodes for a Krell Klone KSA100 lying in stock.

2.2mA or 2.4mA according to me specs for the 5306 / 5307
4.3mA or 4.7mA for the 5313 / 5314
How was the Krell Clone, that was something that I was looking into doing at a later stage. The headphone amp is kind of my learning curve.
