The table shows the exact amount of precious metals in grams per 1 unit of product:
| Gold (Au) | Silver (Ag) | Platinum (Pt) | Palladium (Pd) |
| 0,01008 | 1,967652 | 0 | 0 |
Б5-21 (постоянного тока) contains 0,01008 g. Gold , 1,967652 g. Silver .
Given the course of precious metals, we calculate the approximate cost. Multiply the amount of precious metals by the current exchange rate.
Estimated cost= 0,01008g*2840.7$ + 1,967652g*30.8$ = 89.2379 $
Источник питания Б5-21 (постоянного тока) is on the secondary market of radio components 89.2379 $
| Gold (Au) | Silver (Ag) | Platinum (Pt) | Palladium (Pd) |
| 2840.7 | 30.8 | 1625.56 | 3085.54 |
