i have no idea why i could measure just one signal...

Im doign a new half-bridge anyways...much better and beefier...

about the ICs...Ive got the main 4420 doing the feedback work...Do i need 
another 4420 to got with the 4429 to drive the GDT?As in hvguys circuit, he 
has his signal go to a 4420/4429 pair..Do i need the pair or just the 4429?
