Yes it is the model 37667 35 kvdc and 30 nF. The cap didnt work for 2 days
before explosion. I ran my coil for maybe second or two ( just turned variac
to max) and the top of capacitor ( where the sticker is ) just ripped and
flyed around the room messing evrything with oil and oil did also spring
from capacitor! So i so i was sad, after i cleaned the mess and taked the
cap out and leave it dry it didnot have any visual damage. After it dried i
tried again, and agin it worked for a few times and then blew forever. This
cap is made from 8 caps, 4 strings in series, every string has 2 caps in
parallel. Every cap is rated 8750 V and 60 nF. I still have some caps from
inside. Intresting thing when i tried one cap from inside it worked ok so i
disasembled it it was black inside and full of holes like swiss chese. So my
opinion is that maywells 37667 are better than Cornell Doublier because they
are also self healing, more practic and so. The only problem was in my
Maxwell that the seller sucked all life from him and sold it to me. Does
anybody on the list wants to sell a maxwell HV cap any model at reasonable
price? Maybe somthing like Terry Blakes capacitor?
