As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
Good price for a 10 turn, & 10 turns make great bias pots!
These are great for those precise adjustments, like biasing tube amps, or a fine adjustment for a function generator. Okay, a bias pot for a Fender amp is 10K, and for a Marshall amp it is 22K. No problem! Give yourself some extra leeway! Go with 12K or 15K to dial it in with better range and better control. Remember 1/ 1/R + 2/R = R, so for a 15K pot put an 18K resistor in parallel with this 100K, and use it as is. No need to use a 10K at all! You will get around 15200 ohms, and the linearity is affected to such a tiny extent, it wont matter. For a Marshall pot, lets try 30K! Put a 47K in parallel with this and you will get about 32K. If you want 22K put a 30K in parallel with this. Use a 33K for 25K. The 10 trun means dialing in that bias voltage will be really precise,. and if it gets bumped it wont get knocked too far out of whack! Lets say you want to put a fine control in a function gen. Use the 10K and put it in series with the coarse adjustment.
