Yes, whichever you go for you do appear to be short of a power supply. Which one to get will doubtless depend on budget. And also budget for a service if necessary. Do you have a Burndy for the SNAXO? If not, budget for that too.
Personally I’d go for another Supercap and burndy for the Snaxo. Is this all olive? If so an olive SC should be reasonably priced even when accounting for a service. Cracking system that will be. SBLs?
Edit. In the meantime you can power the snaxo with a Hicap.
Hi yes, SBL’s (of course) And I have a Hicap spare now which I could use on the Snaxo for the moment until I can find a Supercap. Just need some more racking and some more Nac A5 now.
