1810-0146 replacement

[tomcircuit]

My axial inductors arrived, but I couldn't really find a nice way to tack in the 68uH inductor that didn't physically interfere with the innards of the HP-55. I decided to construct a replacement array from three 120uH inductors and one 68uH inductor, all "1/8W" size. I used a solderless breadboard as a jig to hold them all in place while I trimmed leads and soldered a common "rail" across the top of the four inductors. I carefully de-soldered and removed the faulty inductor array, installed my replacement, and then re-assembled everything.

At power on, instead of seeing "0 00" I was greeted with "0.00". Problem solved.
