And many people have blamed their lack of ability on the parts, but it’s not the parts fault usually. It’s more likely the lack of troubleshooting other defects in the circuit And it’s convenient to blame NTE, but that’s not usually the real cause of failure, just a scapegoat. There are some critical circuits where a substitute just won’t work correctly. For instance if you’re replacing a single output transistor in a group. I’d prefer an OEM part so that things stay better matched.

Secondly, “crossing a cross” is not a good idea without some additional research from looking at data sheets. Here’s why, for example.

However, it is rated at 1W. Remember these are substitute parts so as long as the max ratings are equal to or above the original, they are generally considered acceptable by companies such as NTE. So we end up with a part that is rated at half of what it needs to be. In short because it’s confusing: However, Transistor C is rated for half the power of the others. I’m not saying don’t do this. It’s a worthwhile tool when necessary.

But it is just that- a tool. You need to compare specs on datasheets to make sure the replacement part will work and stay working. NTE parts are crude approximations to the real dayasheet they substitute for. It is only the flexibilty of the average circuit that lets you get away with NTE parts.

If you have a row if output transistors in parallel, as you will in most large power amps, NTE will cross the transistors. But if you insert one NTE in a line of say Motorola parts, it will have been made on a different line by a different process. So you cannot trust it to track well in terms of gain or 2n33567 importantly thermally. You can wind up with an NTE transistor that either hogs the current or one that 2n3576 turns on as hard as the others daasheet so is not up to the task.

This is important, hell even the Peavey replacement guide warns against mixing transistor brands. NTE parts as a rule cost three to ten times more than the parts they replace.

That is a hell of a price to pay for a little printed baggie around it.


As Dude points out, NTE might offer up one sub that covers a 20v, a 30v, and a 40v transistor. So you can never assume that if all three cross to the same NTE that they are also the same. NTE dataaheet cross them to some NTE types, but the main feature of the and is that integral heat sink.


And local technicians can grow up never learning that difference.

Education is what you’re left with after you have forgotten what you have learned. Originally Posted by The Dude. Last edited by soundguruman; at Originally Posted by Enzo. NTE’s glory days are past. Using the NTE crossreference book was not ideal can you say swapped pin assignments? I still use them occasionally I rebuilt 2 Hartkes 2 years ago with them. It has all the stuff you want, so if you can get copies, it’s worthwhile. Valuable stuff, even if you don’t buy NTE parts, the information can be quite helpful.
