VTVM resistors

[Neil Morrison]

If you can't find the ones you want you have a few choices. One is:-

"Set of 50 1/4 Watt Metal-Film Assortment $4.99 Brand: RadioShack
Catalog #: 271-309 Model: 271-309 Where to Buy: In Stores
1% tolerance. Set of 50, 5 each: 10, 1k, 10k, 100k. 4 each: 47, 100,
470, 2.2k, 4.7k, 1MEG. 2 each: 150, 220, 15k."

You'll have to buy several packs and combine them to try to come up
with the values you need.

Or, you can try going through regular 5% carbon film and hope you are
lucky. I've tried this way - you need to go through a LOT of
resistors.
