R51 burns when the transistors go short. Standard BUX84 and 85 transistors are with the non-insulated tab. Super Skill Shot Shop. Only sure way to test is out of circuit. I have seen some transistor have an insulated tab which makes mounting more difficult, so check specifications.
Based on what I have seen on the newsgroups and on pinside – there are quite a few electronics type people here Same thing is going on with LMK regulators. BUX84 is another good part number. I should take a formal class some 2n384. I don’t follow the ‘running cooler’ line, though. Topic Gallery There have been 3 images uploaded to this topic.
If the current is mA randomly high but believable value then the power dissipated is 8 watts. Replaced the 2n with the rest of the HV Regulator components.
Thermionic Pinside member 3y 41, There have been 3 images uploaded to this topic. Hardly gets warm to the touch after hours being turned on. Had some issues with a Bally SDB.
Lots of vatasheet with linear and switching power supplies on that job as well as solenoid drivers and mechanical stuff. The BUX84 has slightly better Junction-to-case thermal resistance than the 2N probably comparable to one used above. 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.

I was in construction all my life and I missed out on this electronic stuff. Being able to put components going in and out. LMT might fit as the pinout would match.
By the way, my Meteor has a CPU repaired by you barakandl. Great to see you’re enjoying Pinside! A monster heat sink like that may make that part last literally forever. Been working as an electronics design engineer for 30 years same company the whole time.
These transistors you can test with your DMM on diode test in a conventional way. Here is how you can mount a TO package transistor with minimal modification.
Please donate to Pinside, support datashheet site and get a next to your username to show for it! Unless I’m missing something major, it looks like this transistor is neither difficult to find nor expensive Genie Coin Shooter Rod.
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.
Then i started get into the theory of how and why things work the way they do and i am still shakey on it. My day job pays the bills.
