Just scored the accompanying black livery Threshold FET ten/hl with 'E' Series psu for my SA/1's
What amazes me time after time that Threshold gear seems to be so reliable.
I've had dozens of them and apart from one faulty output transistor in a S/1000 Series II, it just always work.
And bulbs for my SA/1's which I bought 50 of them but only changed two of them over the years![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I've never seen any Thresholds at repair-facilities. How can that be? Are they conservatively build, gone through a perfect part selection process when build, have a simple topology...?
Pass Labs will probably the same in this category.
So I do not feel the urge to replace any parts like lytics or so but maybe I should.
I did replace the eight Mallory's in one set of SA/1 and put a thermistor in them as a rushin current limiter, that's it.
Amazing stuff!

When someone says, "I've had dozens of them..." And if we are talking about reliability, are we talking about, how much time has expired in hours/years/decades when device is operated normally vs. "Abused"?
If one says, I've had dozens of them...how long in time had the device been owned?, one per year? , five each year?...OR have all dozen been running full power 24/7 for a decade or two ? If indeed you have owned a dozen in a span of seven years time, that is not much time they could have been running.
PS, the first photo shows a full-wave bridge & other devices without appropriate heat-sinks...so much for engineering design details. Those holes in those devices ain't there for decoration... (Not a fan of derating)
