Karl, just for grins try replacing all the lamps in one series circuit with o=
nes of the new types & see if they work. It may be that even though the lamp=
s are rated for 3.5v that they are rated for lower current than the original=
 ones, which would cause the new lamps to drop more voltage than the older l=
amps when mixed.=20

Peace,

What am I missing?

Thanks !
Karl
