My Taxi pop bumpers got weak for a few minutes, then stopped working altogether. F3 was blown, also D12 on the Aux Power Driver board and Q73 on the CPU. Should I check/replace anything else before I fire it up?
Thanks.
Edit: also, spoons are fine & not stuck on

Replace the pre driver for Q73, ohm the coil for the correct resistance. Replace the coil sleeve and check the plunger and coil stop for mushrooming.

Thanks! Replaced Q73 & all is well. (Already had rebuilt pops)
