Can anybody clue me in on the proper channel size for the dial glass on a 40-190? I'm looking at Antique Electronic Supply (<!-- m --><a class="postlink" href="http://www.tubesandmore.com">http://www.tubesandmore.com</a><!-- m -->) and finding three different sizes:

Small: 5/32"W x 3/16"H. .090" internal gap
Large: 7/32"W x 3/16"H. .080" internal gap
U-Channel: 7/32"W x 1/8"H. .100" internal gap

The U-channel looks to be the closest to what is already present; can anybody offer me a hint? I'm ordering up 4 tubes (two for my 40-190, two for my 40-180 chassis that I'm going to use as a "practice" refurb before I tear into the chassis that goes with my cabinet) and am attending a few other miscellaneous issues while I'm at it.

This winter I'm really hoping to finish the necessary work in my garage to make it hospitable for work on old radios... the 40-190 is shamefully dusty.

But at least I have all the pieces except the lower antenna strut, and I can fabricate that.

Oh! What dial lamp do I need? Might as well get a couple of those, just in case.
