Lots of shit on ebay with no real specifications to be found. old, appears only in catalogs.. new versions cost order of magnitude more.
Is there some way to estimate if something is like 1 watt, 10 watt, etc?
Is it a safe bet to say if somethings got N connectors on it, its good for 10 watts?
Same with isolators: Can you find one of particular size and assume others of similar size have same power handling capability?
how about filter pole count estimation?
what a fucking mess
can you measure temp of these things to determine usability... like run for a minute and see if its physically hot? or is it gonna be internal problems that don't couple well (i don't know whats in these cans).
