Result of a swap: a Stern Trident from 1979. Electronics copied from Bally, mechanics
a little bit different. The game is in good condition except the lower slingshot arms
need to be replaced. Fortunately new arms were included with the game.
The playfield is in decent shape.
Trident has worked fine, and is a quite nice game to play. But suddenly the displays
went all black! Of course, the fuse is first suspect. It is in solenoid driver board,
just as in Bally games. Blown. OK, replace with new, good displays again! But why did
it blow? Better check the display voltage to be sure. It is 170 V, just fine. Maybe
the fuse was just old. Close the backbox and begin playing... SNAP! Blank displays!
Now what? The fuse is still good, and the voltage is 170 V as before. But no displays.
After 10 minutes, I found another fuse on the back of display panel, under a big sign
saying "DISPLAY FUSE"... and that was of course blown. There must be something wrong.
And so there was. One lamp had fallen out from backbox panel, right onto one display board.
Metal base shorted something, fortunately the display fuses were not oversized. Worse
things could have happened for the display or CPU board. Off with the lamp, in goes a new fuse
and now it is working again.
Trident was bought half by me, half by Mikko. But because the Paragon that we acquired about the same time,
felt somehow less playable for me than for Mikko, we decided to adjust the ownerships: Mikko now fully owns his old
favourite Paragon, while the Trident is now all mine. Not a big deal, since all the games are in one place.
But anyway it is nice to play a game that is completely yours. And if there should ever happen any mishap
during repairs - well, you are allowed to break whats yours.
The game moved on to its next owner.
