ive got a dead nt-2701. i ordered a cap kit, but wanted to test out a few things while waiting. first question is what to use for ground when testing b+ ? the chassis isnt ground. is there a ground test point? the manual isnt clear on that. i have Dc voltage coming out of the
bridge rectifier, but that as far as ive gotten, not knowing what to use for ground to test B+.
i already changed the tda-4605-3 IC, as ive seen quite a few of them bring a neotec back to like, but didnt help. any thing else on these that is a common fault? its out of a golden tee, its VGA ?

thanks
 
i thought about the green wire, but being as its dead i wouldnt be sure if its dead, or my connection is wrong. also, further looking , i think the 2701 is ega?
