I see Sony sells those for (gasp) $22.55 each!

NTE has an Equivalent NTE283 for $10.53 but I wonder if it would hold up?

Eric-

Decades ago, I worked on one of the early 12-inch Sonys, probably the KV-1201 that I have the manual for. One of that set's numerous separate problems was a vertical-sweep problem, and I remember installing two replacement-type (ECG or other) output transistors. They lasted a short time (minutes to hours), then one or both blew again. I then bought the "real" Sony parts, and they were fine. One of the few or only times I had to have OEM transistors in a device to make it work.

Your set has a horizontal issue, not vertical, so with luck it will not have the same problem.
