Thanks for the links!
I read the badcaps thread and it covers the same ground as the ones I read yesterday on eevblog. Interestingly, both are driven almost singlehandedly by the same tony359 guy.
I don't doubt tony359 is experiencing the issues he describes at length. Due to the lack of corroboration from the community, however (and the T3A is apparently a very popular unit, so logic dictates that many users would be complaining about the same issues), Occam's razor says tony359 is the unlucky recipient of either a defective unit or a defective handle.
In that case, why can't a guy like him who runs a YouTube repair channel just take the thing apart and diagnose it instead of bitching about it on forums? It's not like a soldering station is a bafflingly advanced device, and besides it would make for a good video.
Maybe he should send it to Mend It Mark to get an expert opinion
