What are those problems you speak of ......just curious cause I have a clone on the way
If you search for "Ody problem" or "Odsseus problems" you'll find plenty

But to save frustration, I suggest you read the thread relating to the exact clone you're getting. I have the Terminator and Term-C, but as you know there are a lot of different clones out there. So far the Term seems to be the closest I've found to the Ody. Not that I'm any consultant on the matter
@dwcraig1: I had that o-ring issue for the first time last night after a rebuild. I found one tiny hemp thread keeping the o-ring at the top from sealing. These units have to be cared for; you gotta keep 'em squeeky clean
@LucidAce: I've noticed that bubble. Sometimes I catch myself trying to see how small I can make that bubble. I've not experienced any pressure issues you mentioned.
Navy_Lifeguard's method of wrapping the negative NR has given me too many problems, so I've reverted back to just wrapping the wire all the way around the unit (sandwiched between the base and the large ring/nut acting as a "washer"). It's a bit of work to get it just right, but my "dancing ohms" are history, and the unit is centering properly. Just sayin'.
