Bigjay, The Bubs are a #7349. 1.26 watts, 6.3 volt, .2 amp, .55 MSCP, glass shape "T", BIPIN Base, 5000 hour life, C2R filament. Try google-product search for "7349 BIPIN", or better yet do "16435ATR". They are cheap & easy. I've had my 16(B) since new (along with a 7, 7T, 15, and a pair of 9's). Decent products all. Let me know should you need anything more. bob berkman, mojave desert
