[Milsurplus] Alignment of tube tester I-177

[WA5CAB@cs.com]

Wim,

The Tech Manual for the I-177 through I-177-B is TM 11-2627 dated 03 August 
1944 with changes up through Change 3 dated 05 March 1954.  I have several and 
they turn up on eBay every now and again, although usually without the 
changes.

But as Bob says, check the rectifier first and look for obvious damage 
elsewhere.  Also, make sure that the fuse lamp is the correct part number.  It 
should be an 81, which is a Single Contact Bayonet based lamp rated 6.3 volts 1.05 
amps.  Someone could have put a 12 volt automotive side lamp bulb in its 
place.
