success! works like a charm... 
I ended up using the 6.8 volt 5 watt. the 9.1 clamped @ 9.2 but the spike from turning it off and back on quickly was still blowing the bulb. that was my second concern.
just out of curiosity, for the rapid off-on test. I tried a modern 47 (AML from pinball life) and an NOS Tung-Sol 47. The AML blew @ 9.2 and the Tung-sol did not.
I did suspect part of the problem here were the cheap, modern bulbs.
Also.. No 35Z3's were destroyed in this test...
I did test voltages on the tubes as well and all filament voltages are where they should be.
Thanks Again, Mondial
