Well, here I am with another power supply. This time it is a venerable Lambda brick.
| Manufacture | Lambda | |
| Model | LM B-15 | |
| Serial Number | D27233 | |
| Voltage Output | 15vdc +/- 5% | |
| Output Current | 80watts. |
I got this beast a garage sale and for only 12 bucks now let us hope its really not just a brick. So the first thing I did was attack it with my tools, pulled it apart and gave it a good brushing to get rid of the dirt, webs, and just crud. I have included some pretty snaps, and I know how you love to see the inside of this stuff, to show you why this stuff is unstoppable. I found this power supply listed in a Lambda catalog from 1974.

Next item is too put some wires with power on it and see if this 'brick' works.
