I've been fixing an Orban broadcast processor and if they want a
particular ressy .. then they just get them made;!..

20131.499.01 RESISTOR, 1/8W, 1%, 49.9K R23

Oh no they didn't! And no, the pantomime season hasn't started early!

All of those values are standard values in the E96 series of resistor values!

E96 ( 1%): 100 121 147 178 215 261 316 383 464 562 681 825
102 124 150 182 221 267 324 392 475 576 698 845
105 127 154 187 226 274 332 402 487 590 715 866
107 130 158 191 232 280 340 412 499 604 732 887
110 133 162 196 237 287 348 422 511 619 750 909
113 137 165 200 243 294 357 432 523 634 768 931
115 140 169 205 249 301 365 442 536 649 787 953
118 143 174 210 255 309 374 453 549 665 806 976

Two significant digits (plus the multiplier) are sufficient for all the lower
orders (E6 to E24) but from the E48 series upwards, three significant digits
(plus the multiplier) are needed ...
