Got the old girl up and running with only a couple of issues.
Some repinning and a couple of new diodes will hopefully sort my Vari-target issues.

My biggest issue is the drop tqrgets not resetting.
Thinking the issue is mechanical.
In test mode with the playfield up everything fires and will consistently reset properly when 5 of the 6 targets are down.  All six wont get there.... with 6 down none manage to reset.
Playfield down I can only get it to reset 3 targets.

Got New coils each around 23v.

Had it apart. Cleaned. Everything moves freely.
Longer springs on the targets.... shorter ones to the frame.

Just seems like there is too much friction with the targets.
Ive played with the coil depth without any noticable change.

There is some play in the links to the plungers. Cant find them in Oz... part A-262 from memory.
What am I missing? Its driving me nuts!!!!
