    It seems like I always need a resistor that I don't have and it's a pain to drive an hour to the electronic store near me to get a package of two pieces for $3-4 and it's not for sure they will have what I might need because the selection is very small and limited and probably quite old to boot. They sell more items such as testers and equipment than they do components for electronic restoration so can someone recommend a Mouser " starter kit" perhaps that won't cost an arm and a leg that might have most types and values included that the Marantz units normally require or is there even such a kit? Or if no kit what would be the best way to order, such as most often used types and values that cover most of the bases.

    I have bought metal film assortments off Ebay. Some say they are of dubious quality because they are unbranded, but about 99% of mine measure within tolerance. Just check out your seller before ordering.

    I don't know if they sell assortments, but Tayda is a reputable Ebay seller based in Thailand.

    Ok I will check that out. Thanks.

    Metal Oxide kits are more difficult to find on there than metal film it seems. Maybe because they are cheaper to produce??

    I have hundreds of thousands of resistors.
    Lucked into nice assortments from different places.
    One was an electronic tech school drop out yard sale.
    One large bin was thrift store score.
    One was a huge pile from Bryce, he bought out any sale with tubes so old TV and Radio shops stuff.
    RadioShack had assortments and I got one of them.
    Many orders from mouser.

    The point?

    Damn difficult to keep stored and sorted and I never seem to have the one I really want.

    I find that I really need one very rarely.

    I have probably spent more time sorting and storing and trying to maintain resistors than actually needing them and using them.

    Mouser has large assortments but they are costly.

    Usually I look at a schematic or two and get an idea of the most common values. However I find I have ALWAYS had to place an order or THREE every time I did a project. If it wasn't a resistor it was a transistor or odd ball cap.

    Capacitors were easy to stock up on. I just didn't get as picky on voltage ratings. Newer caps are smaller with higher ratings so size was no longer that critical. What I did was tag on a few extra pieces with each order. Some power resistors, some caps, a few common transistors, etc... And when I did order parts I ordered 6-10 extra just in case I needed them for another project in the future.

    Now that I no longer do repairs I have a large bag of parts kicking around. I'm sure those caps are going to dry out one day and no longer be any good.

    Do you have that LARGE jumble bag of resistors you keep telling yourself you have to sort out one day? I tried to keep them in the bags Mouser sent them in but I couldn't read them half the time. Staples sells those little brown change bags. Using a marker pen in LARGE print I wrote the value/values of what's in the bag and that seems to be working pretty well.

    My Ebay assortments come on ammo tape. I put them in marked 8 1/2 by 14 envelopes.

    here's how I do it.

    buy plastic zip-lock bags off eb. 2x3 will work, 3x5 are better. sort by size (1/4, 1/2, 1W, 2W, ...)
    then by value and by boutiqueness (cheapy MFs vs hyphenated like Vishay-dale, or multi-syllable
    like Rodenstein) and then bag then with a white address label. lastly plop into small boxes by
    wattage and also labelled as such.

    when needed just pull the boxes, liberate needed values and stack for use. if you're existentially
    anal, then keep bags out as they drop below the economic lot for re-order. economic lot algorithm
    is cheaper to buy at qty=10, than at qty=1 pricing or for those with a Finance MBA when
    qty 10 is cheaper than, say 8 at qty=1 pricing.

    do same for caps. decide whether to stock only axials or radials. Axials turned radial are cool but
    radials turned axials look like skinny sumo wrestlers and look better. not to mention for the
    angels-on-a-pinhead religious - there's less undetectable inductance.

    all my caps and resistors take up about 3 linear feet of 8-9" high shelves. so you'll need a bookcase.

    I buy Joe Knows Electronics resistors on Amazon. They are boxed and individually bagged and marked. Very handy!

    I have gotten WAY in the past from Digi-Key.

    I actually got the drawers and trays on a couple assortments. The gigantic pile from Bryce came in moving boxes with parts bins full and semi sorted. I spent time cleaning and bagging that up. Mostly larger stuff from tube days. I am probably the king of 2 watt carbon comps.

    I scored a pile of high watt cements from another old guy sale. TV stuff again.

    I literally have boxes full and all sorted.
    It's a massive amount.

    It has been handy when I do need something odd. But hunting the odd one takes time.

    I have some nice drawer racks and one of these days, I'll get those in play.



    Really.




    One of these days.
