Only sure way to test is out of circuit. Currently updating design of high end communications equipment for satellites. Unless the heat sink compound was dried out, I do not see any reason for the transistor to be any different in temp.

It’s a matter of how much you are willing to spend and personal preference. Other resistors in the circuit test at proper values datasheet do the two diodes. Since you have not changed the heat sink then the overall temperature should be nearly identical to that of a 2N Topic Stats 43 posts 14 Pinsiders participating Latest reply 2 years ago by eh97ac Topic is favorited by 17 Pinsiders.

2N NTE Equivalent NTE T-NPN SI SW LINEAR AP – Wholesale Electronics

That is valid part number at a good price. Thanks – great information. Probably a dumb question – but if the kta don’t get that hot why not eliminate the heat sink. Lots of experience with linear and switching power supplies on that job as well as solenoid drivers and mechanical stuff.


These almost always fail in a set of three.

I always use BUT11A without any problems. Genie Coin Shooter Rod. So I found this thread and ordered up a 10 pack of BUX85’s.

Thought I’d dig this up. For current problem — time to retest all three transistors.

BUX84 is another good part number. Certain page elements may have been deliberately hidden. Did you know Pinside is able to run thanks to donations from our visitors? I was in construction all my life and I missed out on this electronic dataaheet.

Datahseet You are not signed in! Now think I may have retried the and the other A dab of silicone would work too or the pcb has screw holes.

The slight difference in gain won’t matter as that is already accounted for by Q The BUX84 has slightly better Junction-to-case thermal resistance than the 2N probably comparable to one used above. None have come back with problems. This page was optimised for printing. The Flintstones Pinball – Sound Rom. A monster heat sink like that may make that part last literally forever. R51 22K was very hot. These transistors you can test with your DMM on diode test in a conventional way.


I’ve now got a few for when I do board work. What is the proper way to test the and the transistors? The BUX84 i found are plastic non conductive on the mounting tab.

Can’t beat the price.

Now i fix pinball boards to pay for my hobby. It’s a special suffix to get the version with the insulated tab actual suffix varies between mfrs. It doesn’t run any cooler than the original design which also really didnt warm at all. Next i understood how to test and figure out when all the different types of components are bad. By the way, my Meteor has a CPU repaired by you barakandl.

Roadshow Pinball – Sound Rom. Here is how you can mount a TO package transistor with minimal modification. But turn that V down to save your Plasma tubes. I bought a bunch of corroded trashed pinball machines and forced myself to learn so i could fix my games.
