We need more sticky threads with sources for common hobbyist parts such as:
High tolerance resistor kits - better than 5% tolerance
Audio grade capacitor kits (polystyrene, polypropylene)
High quality pots and rotary switches
Basically the stuff that has limited to no coverage by Digikey, Mouser, or Newark.

agreed, a database of known good parts would be great.
i'd also like to see an improved search facility, i get better search results from google than from the diyaudio.com internal search.
and also a thread dedicated to audio related mathematical formula with explanations for noobs like me.

While I agree with the need for genuine information on high quality parts for audio ( leaving aside cost ) the big problem on the www is overcoming the hype /propaganda /blatant advertising that uses colorful words to describe non active parts like --
"out of this world"
"a gift to the audio designer "
"only a quarter of the price of xxx "
and so on .
There is only one way to find the truth that is by tried and tested parts used by the top audio designers not some hype from a manufacturer under pressure from its shareholders to increase the $$$$ in their pockets.
How does it SOUND --- to you as that is how a product is judged .
This has split engineers into two camps and you don't need me to tell you who those audio gurus are -- arguments become flame wars ,editors intervene but if you have made the decision on those you specify and I agree with you although that is my personal opinion and I can understand others disagreeing but YOU are the one doing the listening and each of us has our own basis for judging "beautiful music " .
While acoustic tests by audiologists try to come to a set standard and your hearing range is judged by that scientifically that is not the end of the matter as the auditory nerves go to the brain and its the BRAIN that judges audio and each person is an individual in their response to musical reproduction its called "individual personality response " .

I'm in the 'objective' camp. If results can measured independently and consistently, then they are probably accurate. You can objectively measure that X% distortion exists, regardless of whether X is high enough to be a concern.
And sometimes 'quality' doesn't have to reference the audio portion - there are circuits where the taper on a dual pot really needs to be well matched for it to work properly, or where a two slope "log" taper doesn't cut it.

OK - here's one source for 1% resistor kits:
CBR-12 Nova | Nova, CBR-12 Metal Film, Through Hole 48 Resistor Kit, with 1480 pieces, 10 → 1MΩ | 156-2571 | RS Components
Never came across this in years of looking.

i dont know if your resistor kit is such a good idea. does this company produce all of these resistors or are they made by a third party ? is there consistency within the production runs ? has anybody used these with good results ?
The actual resistors are made by Vishay. The Nova kit is CBR-12, available in the UK from

I don't know about above mentioned kits, but I have bought several resistor kits from China (one through hole kit, and two SMD kits - 1206 and 0805 'book type') and they are ok.
When I need something 'especial' (for example, for feedback circuits of an (ultra)low-distortion device) - I buy brand resistors not on Ebay, in a local shop (and they buy them in their turn somewhere in Europe - on a TME/Mouser etc.).

bought recently a FKP kit from Wima to have some polypro caps on table.
Not sure if Muse or others, are offering aluminium caps kits for audio.

A E96 resistor kit is a lot of parts that you may never need. Why not just buy the values you need and not waste your $ on valued you will never need.
The only kits I have are E12 1/4w resistors and some some ceramic disk cap up to 100p, the rest are bought as needed for each project.

E96? The kit I posted is E12 minus a few values (full E12 between 1K and 100K only). And it's still nearly $100.
Okay I did not look at your link. But my point still applies to spending all that $ for values you may never need. Esp 1% resistors regardless if e96,48,24. Up to you how you want to stock your lab.
A forum page or thread with links to very good threads can override the need to use sticky threads. Sticky threads make sub-forums combersome to browse while links in a separate page/thread do not.
This can be organised in a sub-forum with a fixed number of threads named after the forum's subsections. So, a link to a thread under 'Solid State' would go in a thread named 'Solid State'.
Alternatively, a sub-forum can have a page named 'Stickies'. The page would list sticky threads alone.
