Just got a 25" amp and have some questions. What's the difference between a blue and tan reflector board?
Also do 25s use different boards or is it all universal. Im planning on stock piling so spare parts and didn't know what to look for?
Thanks

Deflection Boards will all work

Blue are the oldest, then tan, then Green

Green has a few mods built in
There are 8 diodes which need to be fitted whatever model you have
There also are some old blue board missing the width and height pots, which would normally be hacked onto some resistors.


I am making the deflection boards PCB from scratch shortly, and have sourced all parts to make these from scratch, so there is no real need to stockpile.

Hope this helps, so any board will work in any machine, as long as you do the pot mod and the diode mod

Congrats on scoring a grail monitor by the way
 
Thanks I just got my star wars cockpit in the basement this morning can't wait to get off work and tinker. I'll keep a look out for your boards will they basically be plug and play then?
