[Boatanchors] OT Maybe.. WTB

[Ron.K3PID]

Pete. I am very much aware that the ECG & NTE are "replacement" parts! Unfortunately, the original manual only references the Crown part number which cross references to nothing and someone in the interim has repaired it using the ECG725 so that's all I have to go on. My guess since most of the power devices are Fairchild, this was probably a private label UA 739... but that's just a guess! I posted the request for the ECG & NTE part numbers because I thought it more probable that someone would have one of those parts...maybe a bad assumption..

  Green Brook Electronics is shown as a supplier for the NTE725. It might
  also be helpful if you mentioned what the original part number is that
  you're trying to find.

  "ECG" and "NTE" are the prefix codes for replacement semiconductors and
  generally not OEM codes.
