I think I've acquired more than I need. I'll try to see how many I have. But, you're not getting the blue Arcturus ones!

Thanks! I'll take what I can get My only 71A is an ST type.
I just did a little comparison of the 183 and 71A.
Same 5 filament, but the 71 draws only 0.25A vs 1.25A for the 183.
Also the 71A is about 0.8W vs 1.8W. Other than that they looks pretty close.
