MX-949A/U Tube Socket Adapter Kit for the I-177
This is a "breakout' box that adds additional tube sockets to the I-177 tester. These can be a bit hard to find, but I stumbled across this one online and bought it before it could get away. It's dated 1953, the same year as my I-177, and is in good condition except for the large ceramic socket.

The original paint only has a few minor dings and chips, not enough to justify repainting it. All it really needed was a good cleaning. It definitely makes the I-177 more versatile.
There's no electronics inside this unit, just wiring from the tube sockets and octal adapter cable that go to the numbered pins and jacks of the front panel. |

The large ceramic tube socket was cracked, which seems to be a common malady with these units. I epoxied it back together and filled the cracks with a porcelain filler for appliances.
