My Transistors, original or copy?

A heads up, NTE has closed for good...it was a Philips North America company till 2001, then changed owners.

The people who sold it in 2022 are saying bad things about the current owners, I think that in view of a shrinking market, and NTE itself selling parts of dubious quality marked with their house numbers, the demise will not be regretted.
 
Back in 88 NTE was a competing line to ECG. Somewhere along the line it was all absorbed/assimilated into one. We had a saying back then (that’s still mostly true today): “But ECG is PHILIPS, and PHILIPS isn’t worth a $#**”.

They survived for years due to the HUGE profits that the service shops would make on them, because they were 3 to 5 times the cost of industry standard types. The % mark-up was the same, so the higher cost part was “preferred”. Electronics are rarely repaired at the board level anymore - throw the whole thing out, rather than replacing the four burnt out transistors and the resistors that were collateral damage. The original market has evaporated. People who still rebuild/restore/repair good vintage gear and actually give a damn have always avoided ECG/NTE so nothing changes there.
