.001 ceramic

[bullpeters]

Hi.I need a .001 uf CERAMIC capacitor for a train wreck clone. I can buy ONE for .34c but the freight is $15!!! I don't really want to argue the very arguable need for this particular part. Its a Trainwreck clone and for once i want to try it right. Any thoughts on salvaging one or perhaps a good sort would drop one in the mail for karma,or at the least some paypal?

Look for 1000p or 102 markings on old capacitors. The flat pancake style usually about 2mm to 6mm diameter and <1mm thick.

old TV's, CRT monitors, and PC power supplies are full of old parts. Walk around early in the morning on garbage pickup day.
The ceramic caps are not usually what failed. I cut them up occasionally for resistors capacitors and diodes. The electrolytic caps are trash.

You will most always run into the basic shipping charge if you order something from a supplier. One cap or a thousand is still a small package that must be shipped, doesn't cost them less for being almost empty.

How about walking into a local electronic repair shop - televisions, stereos, computers, even appliances, and ask them if they have a part they would sell you. If you walked in here, I;d probably just give you one. My sales tickets cost me 15 cents each. SO rather than use up a ticket, i ive the occasional resistor or cap away for free.

You would think that they could stuff one in an envelope and mail it to you !!!!?

Mick,

Farnell now called Element14, R.S. Electronics for mail order within Oz.

Should be a local Altronics distributor nearby which will have them.

I built a trainwreck, disc ceramic is the go for that cap.
If you get desperate PM me and I'll put a couple in the post from Adelaide.

If you are a member you can see my schematics etc. here - the "Junkbox Trainwreck" built from an old Ozzie AWV PA Amplifier.

Thanks Ian. I will let u know. Glad for the confirmation about the cap. Thought that the ceramic might just be trainwreck nonsense. I am using 6sn7 triodes for the output, (Idea from AX84.com) Fully regulated power suppy, the bias, the heaters, everything. Powder coated the chassis. Something nice to keep.

The "Junkbox Trainwreck" I did. For your possible interest.

Note you end up with a spare 1/2 of a 12AX7, I added a "wrinkle" of my own by using a parallel input to take advantage of that spare triode. The 2 triodes at dissimilar operating points for a bit of harmonic emphasis.

Cheers,
Ian

wish you hadnt shown me that. I am just connecting the last bits and i dont want to change anything now. I expect to get about 2watts flat out. I cant imagine 35 watts in my house!!
really nicely drawn schematic.Impressive

It is nonsense - no specific need for a ceramic capacitor, any 1000pF of high enough voltage will be absolutely fine.
