Paragon center pop is staying locked on transistor in q13 spot on the driver board is super hot I don't see any shorts in the wiring and all switches are clean and gapped. Everything on the board front and back look good with no burn spots and no hacks. Any info would be helpful

Quoted from barakandl:

Try this. DMM set to diode test. Red lead on ground, black lead touch the transistor tab/middle leg. If it shows less then 400 on your DMM, it is dead.
I don't think radio shack is going to carry a transistor close enough to what you need. Get a TIP-102. I used to sell these but I am out of stock right now. Try Great Plains Electronics.

Thanks I will do that test now I'll let you know what I come up with

Transistors have a range of 131 to 145 across the board with q13 being no different.but I did do the jumper wire mods and cleaning all the connections with alcohol. Is it ok to use die electric grease on the connections?

Got it!!.. I swapped transistors and it works only bad thing is now the drop target reset coil is not working no worries though I just removed the wrong one but the locked coil is fixed. Thanks for all the help guys couldn't have done it without yall. I def learned some new skills today. Looks like I'll be ordering some new transistors tomorrow.
