Hi,
I am brand new to this forum. I am looking for help/ advice. My Dad built and repaired and collected vintage tube amplifiers for his whole life. He has been done with that for a few years and I have been slowly rehoming things. I am now down to the resistors and capacitors of which there seems to be thousands. I am not exaggerating. What do I do with them? Who would want this many? It would be Herculean to sell them in lots on ebay. Any help would be wonderful.

You could sell them as a bulk lot on Craigslist, in the instance that you are in an area with enough population to create a potential demand. If you are in North Dakota on a farm, you got problems moving that sort of thing out. Selling small lots or individual parts is probably out of the question as you would be 20 years at it and end up with a residue of unwanted stuff anyway. You could advertise with or contact ham radio or antique radio collectors in your area to give them a heads up too. If you want top dollar, you will maybe have to think in terms of years but if you are eager to liquidate quickly, in many places that will entail making less than "ebay asking" prices.

If the lot consists mainly of wax, paper or plastic covered, or electrolytic capacitors, and carbon comp resistors, and appears to be over 20 years old, the caps are most likely no good, and the resistors would have to be tested individually with a meter to determine if and how much out of spec they are.

If you post your general location, we might be able to point you to a local antique radio organization, who could eyeball them and suggest any value and the best way to liquidate.

Don't expect too much from the resistors. A local surplus store (that is no longer in business, primarily because of the pandemic) sold 1/4 and 1/2 watt film resistors for about 5 cents each. Your dad may have bought them in bulk originally for the same or less per piece.
The capacitors would go for much more a piece. It depends on the details of those a lot.
You could take a look at places like Sal's Capacitor Corner, advertising here -->, for an idea of what new (not second hand) parts could sell for. Of course a store has to account for overhead, advertising, etc.

Older type resistors typically drift upwards in value way beyond their markings or acceptable tolerance.
So those are probably not of value anymore. You can use a good meter to randomly test a few handfulls of them and determine if they are within 10-20% of marked values.
If not scrap them.

If you really want to avoid extra work for little return... you can advertise everything caps and resistors at some give-away price or free.

Thanks for all the replies.
I think 20 years is about the right estimate of time. I had thought the resistors would keep as a good portion are unused in packaging on rolls.
I already scrapped the aluminum cased capacitors. But I was hoping the other ones that look like ceramic or something would still be of use to someone. Everything is located in southern NH but I am in VT which makes it a pain to list on Craigslist. I do what I can when I go there but just throwing it all away seems like a waste. Even if it goes in a metal dumpster I'm not sure if it's getting recycled.
I thought of building a smallish press and just making resistor cubes.

You could offer all of it here on the classified section.
Take a few pictures of the whole lot and post it here too.
Ask peanuts or a very low price like $50-$100 plus shipping...or just give it all away for the cost of shipping.

It all depends on the type and brand of resistor. If they are metal film or carbon film resistors, or carbon composition resistors made by Allen Bradley, then they are probably fine. Carbon composition resistors from other manufacturers may have drifted in value considerably.

Since this is located in southern New Hampshire, you might try contacting the New England Vintage Electronics Club and either bring it to sell at the next meet (September 25), or ask for it to be advertised on their email list.

Get rich on things like this you will never.....I would just put it in the classifieds here, and take the best offer.

Talking about meditation are we?

The Meaning of the Om Symbol. 'Om', 'Ohm' or 'Aum' is a sacred sound that is known generally as the sound of the universe. Om is all encompassing, the essence of ultimate reality, and unifies everything in the universe.

The "close to zero value" statement is not allways true and there are exceptions.

For instance, N.O.S old carbon composition resistors (made by Ohmite, Allen-Bradley,... see pictures) are in great demand in the vintage guitar amps community and not cheap. I checked a few samples of these old Ohmite "Little Devils" and all were still within their original 10% tolerance.

Old N.O.S paper dielectric capacitors, especially "Black Stripe", "Bumble Bee" and "Vitamin Q's" command (very) high prices in the same vintage guitar community and they don't care if these old cap's are electrically leaky (which most are now).

And if you have already scrapped SPRAGUE "Atom" type electrolytic caps you made a big mistake.

Better to be well informed before trashing anything, or selling for peanuts...

No, I resisted it. Had little tolerance for such things.

possibly more by your reactance---namely by your capacitive and inductive impedance.......Say THAT 5 times fast.....;)..)
