Im not trying to derail your thread but how much wattage does the monstacade draw at load?

I bet electrical costs top $100/month to run it. I prefer to tweak on air cooling b4 I go ln2.

I think for the temp control ln2 is a better bet anyday over a cascade, just my opinion tho.

Here my breakdown:
$25 per dewar fill (lasts me ~3 weeks)
$200 - 50l taylor wharton
$300 - F1EE which can be updated to fit any socket for just a couple dollars for a new holddown/backplate

So I assume that for $1600 the mostercade/something similar could be had? I would need to fill my dewar ~50 times to equal the original cost. not including electrical usage each month to run that monster. 50 dewar fills = 150 weeks or almost 3 years of running ln2. in 3 years i bet the monstacade needs a regas and retune. that isnt free either...

Just my $.02
