If you cut the middle leg of the transistor you can use the metal tab as the collector and mount it just like the TO transistor. I have seen some transistor xatasheet an insulated tab which makes mounting more difficult, so check specifications.

Heat in this setup is very minimal. Hardly gets warm to the touch after hours being turned on. As you can see from the back side, no tricks in mounting it.

Fun fact about these driver boards. If R51 is burned, you can assume all three HV transistors are bad. Probably a dumb question – but if the kta don’t get that hot why not eliminate the heat sink. Or use a heat sink for the TO?

Well, with out the heat sink it may get too hot. Adtasheet probably could have used a different heat sink but I wanted to keep it looking factory as possible. Sometimes doing mods like this borderline on what people would consider a hack. Modern and still made replacement for the TO transistor would be a BUX85 at less than a buck apiece. I don’t follow the ‘running cooler’ line, though. Regardless of transistor type – this circuit is still dissipating the same amount of power.

This power is dissipated as heat.

If the current is mA randomly high but believable value then the power dissipated is 8 watts. This power dissipation is the same regardless if 2N or BUX84 or any other type transistor. Since you have not changed the heat sink then the overall temperature should be nearly identical to that of a 2N The BUX84 has datqsheet better Junction-to-case thermal resistance than the 2N probably comparable to datzsheet used above.

But the 2N has better case-to-sink thermal resistance typical of metal can 2n3548. So, the thermal resistance is nearly identical. Unless the heat sink compound was dried out, I do not see any reason for the transistor to be any different in temp. And I see no reason for the heat sink to be at a different temp, either. Now — if the transistor being driven has a different gain then it is possible that one of the 2N’s may be running slightly cooler.

But most of their current is determined by biasing resistors. I was in construction all my life and I missed out on this electronic stuff. Wish I could have learned it years ago. Been working as an electronics design engineer for 30 years same company the whole time.

Currently updating design of high end communications equipment for satellites. Tons of miscellaneous jobs as well. Most fun was the datashert system for people under home arrest. Had wireless ankle straps on the person with anti-tamperGPS tracking that was fun to testbuilt in breath-analyzer didn’t get to test that onecameras Lots of 2nn3584 with linear and switching power supplies on that job as well as solenoid drivers and mechanical stuff. A lot of that stuff rolls over nicely into pinball and arcade electronics which is mostly generic stuff.

Based on what I have seen on the newsgroups and on pinside – there are quite a few electronics type people here It doesn’t run any cooler than the original design which also really didnt warm at all. I was trying to say in this datahseet it does not get hot datasheeg to original component.

I will have to look into finding BUX85 with a non insulated tab. The BUX84 i found are plastic non conductive on the mounting tab. Thanks for all you guys do here. We really need people like datadheet on pinside. I bought a bunch of corroded trashed pinball machines and forced myself to learn so i could fix my games. First i mastered using a soldering iron.

Being able to put components going in and out. Next i understood how to test and figure out when all the different types of components are bad. Then i started get into the theory of how and why things work the way they do and i am still shakey on it.

Tons of reading, tinkering, testing, playing. I should take a formal class some day. Now i fix pinball boards to pay for my hobby. Anything i make on pinball boards funds my next pinball purchase. My day job pays the bills. Standard BUX84 and 85 transistors are with the non-insulated tab.

It’s a special suffix to get the version with the insulated tab actual suffix varies between mfrs. Had some issues with a Bally SDB. Replaced the 2n with the rest of the HV Regulator components. Circuit went bad but can’t figure why. Replaced the 2n and the non-heatsinked and for a few seconds it output the correct voltage then nothing. R51 22K was very hot.

It’s new but already looks burned. What is the proper way to test the and the transistors?

Other resistors in the circuit test at proper values as do the two diodes. Yep — BUX85’s on this page: For current problem — time to retest all three datqsheet.

Only sure way to test is out of circuit. R51 burns when the transistors go short. These transistors you can test with your DMM on diode test in a conventional way. Probably the one I didn’t replace was also bad. Now think I may have retried the datashdet the other I hate re replacing things. These almost always fail in a set of three. If you don’t replace them in a set, you risk shorting them again. Could the lmk be replaced with a t in a similar fashion to using the bux85 for the or is the pin config too far off?

By the way, my Meteor has a CPU repaired by you barakandl. LMT might fit as the pinout would match. I don’t think I would try that. Hey, would this be a good addition to pinwiki?

As 2N’s get scarce only Central Semi making them now at greatly elevated prices. The BUX85 seems to be a viable alternative using method shown above. I have sent out probably 20 driver board using a BUX84 as datasheet HV transistor over the last year or two.

None have come back with problems. I got a few of my games with datassheet too. Bumping cause this is good info and those new to the hobby might have missed a good piece of info. I’ve now got a few for when I do board work. Can’t beat the price. That is valid part number at a good price. Yes, but the center lead – collector, will have to be folded up, solder a wire to the center lead and then attached the other end of the wire to the the tab mounting screw to provide circuit continuity for the collector.

Datasheet metal tab, un-insulated. Unless I’m missing something major, it looks like this transistor is neither difficult to find nor expensive:.

Unless I’m missing something major, it looks like this transistor is neither difficult to find nor expensive: I have probably 20 of these driver boards on hand i need to eventually go through, that is a no brainer to me. In the end it doesn’t really matter as long as the solenoids are clacking and the lights are flashing! Unless I’m missing something major, it looks like this transistor is neither difficult to find nor expensive It’s a matter of how much you are willing to spend and personal preference.

Not long ago when Motorola was making these, new ones were less than a buck apiece.
