[FA:] Triple decker substitution box

I usually just use pots myself, then replace them with fixed resistors when the design is finalized.

Anyone who must yous pots, must be on drugs. Pots are used for calibration, not design! Yikes!

What works, works.

If one needs to use pots to design, it's (whatever "it" is) not likely to work. I simply cannot imagine using a pot in the design phase. They're ugly enough when they're needed to calibrate. Yeesh!

Keith: It sounds to me that you are the one on drugs. Good luck selling your triple decker substitution boxes.... they went out with the dinosaurs. Most design engineers DO NOT use substitution boxes but rather "tack in" approximate values of resistors derived from calculation or educated guesses and/or will use a pot in a finicky initial design when experimenting with tolerances. electricitym

Keith: "yous" pots....... nice grammer and spelling.... maybe you are the one on drugs.... or "pot" ? ? electricitym

No sales? Not too surprised!

I am not surprised either....... you can find this on his website

I can not believe any serious electronics hobbiest is buying these.... even at the EBay bid price of $31 At a few places I worked over the years, the design engineers would roughly calculate or make an educated guess about the resistor value and reach in the parts bin and solder tack on a resistor.... and then change it if need be. I have seen them also use a potentiometer to zero in on a critical value.... and they were not on drugs either as the OP suggested. Dan . . .

I actually understand the "name" and arbitrary pricing. The name is a rip-off of the 99 cent store. The arbitrary price is a way of pointing out what a bargain it is IF you pay less.

I have rarely used a Decade box myself, and when I did it was a L&N .001% unit used for precision calibration.

^^^^^^^ Jesus wept...

Bob: Nice "pick up" on grammar. I didn't "yous" my spell checker for that posting. electrictym . . .
