hey where did you get these silver knobs from?

Gustav said:This may seem a little dumb, but whats a good way to shop for resistors for the switches?
I went to Farnell.com, and by the time I got to the 5th value, I already had.
1. 1 pcs 3 euro resistor to cover one value
2. bag of 50 pcs (minimum) for a second value
3. One value missing
4. One value "ships from the US, add a gazillion dollars for shipping"
Mouser/RS etc results in a similar mess.
Basicly asking if there is a shop that covers the E96 range

Hi Gustav,
I ordered every resistor for all my switches (as per Harpos spreadsheet) from Farnell (called Element14 in Australia... Same thing).
Look for the multicomp brand, they often are cheapest and come in MOQs that aren't too insane.
Also, you can save a few dollars by not getting too pedantic about the resistor values, give or take an ohm here or there. I.e. A 499ohm resistor might be 3x the price of a 500ohm resistor. (Maybe a bad example but you get the idea). This makes a significant difference to the price. Ordering very obscure resistor values is an expensive process... Hope that helps

Thanks. I was a little worried about going off-value, because the differences will add up the way the switch is built, but Ill go for it

Not sure I did it right.
Maybe try this calc sheet for X step positions.

Sorry, but no.Gustav said:Thanks, Harpo! (Thought the negative value was just an accumulated rounding error )
petermontg said:I think I did a basket for all the resistors from Harpo's sheets. It is with mouser 1% tolerance. I'll have a look see.
Edit: Am not sure how accurate it is been some time since I did it. Some are out of stock. It has free postage to Europe.

my pleasure, but this is just a quick and dirty tool, far from perfect/foolproof.prescott said:Harpo, the calculator sheet is just fantastic...
Is it possible to extend it with the HPF, the same way, when I can change freqs and steps?
Look at the headlines or part numbers...BTW, is there info about how to separate the peak and shelving bands?
Look FI at calcsheet row17 and row 200 to get the relation to the 'headline and parts numbers' for the low band.prescott said:But how do you mean "look at the headlines"?
Its just putting the peak and shelving bands to separated rotary switches and thats it?
