Where do I find components?

[Jameson]

Hi, I hope someone can help, im new to sourcing electronic components. I have made a Vellemen signal injector/tracer from a kit and have previously received excellent info from this forum regarding what parts I now need to make a probe. The issue I'm having now is I cannot find any retailers that have the full gamut of components i need; Ive been searching for more than 2 hours and also refering to ads in magazines such as Practical electronics. I dont want to buy these components from 3 different places as the cost of p&p soon adds up. If anyone can provide these items or know where I can source in one go please let me know. What i need is

x1 0.15 uf cap - 400v
x1 100 pf cap - 400v
x2 Germanium diodes (1N34 or OA90)
x1 1 nf Cap - 400v
Some wire to fit into 1mm holed perf board

Thanks for any pointers

Cricklewood Electronics - helpful, reliable, good quality components, and much used by members of this forum. They also have good, responsive telephone service.

I think more info may be needed in order to best help you, I expect your probe will be compact and hand held? If so then small axial lead capacitors would most likely be suitable unless a printed circuit is the basis in which case you probably need small radial leads.
I have an excess of real Germanium signal diodes that will exceed the generic 1N34/OA90 and you are welcome to these as this component is a regular pitfall to the unwary as people try to pass off inferior types.
Most of my capacitors are still in a storage unit while I have building alterations but if you want the diodes drop me a pm, you are welcome free gratis.
And I second Cricklewood Electronics too.

In the 'Where to get sets and parts' section there is a stickied thread for "Recommended Component Suppliers". You can see it at the top of the page here.

I can sort you the caps & wire, diode too probably but a pull not a new one, for the price of postage, but as Mike says more info would help.

Thanks for the replies they're most helpful. I was not aware of the stickied thread that will surely be helpful in the future. So the probe I want to make is in fact a recommendation from David G4EBT on this forum to be used with the Vellemen K7000 tracer. see post 4 in this thread...........

So from my limited understanding of how this actually works (I just want to build it for now) what I need is

x1 0.15 uf cap - 400v
x1 100 pf cap - 400v
x2 Germanium diodes (1N34 or OA90)
x1 1 nf Cap - 400v

If anyone here can provide this then yes please I will pay for postage and parts as expected. @ Diabolical Artificer yes I don't mind if the diodes a used one as long as its suitable. Thanks so much

Looking at Davids nicely illustrated probes, I would think axial would fit snugly inside something like an empty Sharpie type casing etc, I think the smallest physical sized capacitors at the specced Voltage will still be fairly bulky so cunning assembly is called for. Possibly some brands of highlighter would allow more space and still fit the hand comfortably?
Diodes will be in 1st class post this morning.

Mike's sorted you a diode bless him, will look for the caps today.

Found a 1000p (1n) 630v axial & a 100p 500v silver mica, no 150n, does it have to be 150n? It's an uncommon value, I've plenty of 100n's. I'll see if I have some ceramic 1n which may be smaller.

Drop me a PM with your address, Andy.

Edit, looking at the schematic, the 150n is in series with a 68k giving a 3dB rolloff of 15khz ish, so if you use a 100n & a 100k for C1 & R2, it should do the same thing as a 150 & 68k, IE pass everything under 15khz but roll off frequencies above that.
