Quoted from rcbrown316:

I used these for the flicker only because I have 5 or 6 original lamp driver boards laying around.

In retrospect I should have just replaced the board with an altek for a few reasons. 1. all new components 2. these double the amount of connections. for an extra 50 bucks I think it's worth it.
GI is comet single smd natural except in the uterus thing where I used 2 green twin smd and 2 red twin smd's. Under the PF I used twin smd's in all the inserts. I ran out of color matching ones so I just used white because the inserts were in very nice shape.
Left incandescents in the back box. I don't like that too bright and reflecting off the glass

Quoted from Philk:

Might put my Embryon up for sale,

Quoted from Philk:

We'll see I guess, playfields come up every now & then. This is never going to be a restored museum piece but rather a player. There was a line of people looking to purchase this when I got it but unfortunately the gameplay hasn't grown on me.

Quoted from Grizlyrig:

What we also need is for someone to reproduce the playfield.
With Paragon and Space Invaders getting done I think it was a miss to not do Embryon.
