you actually need a shielded brick aka cocktail brick, transformer on an UR brick is not magnetically shielded and the raster cocktail bricks are, unless you enjoy the rainbow distortions and in that case just go ahead and use the UR brick.
repeatedlyHave you actually confirmed that firsthand (i.e., that an unshielded brick interferes with the monitor?)
I actually just finished a conversion on my Centipede cocktail table using a raster brick. I don't see any distortions or anything of that sort after leaving the monitor on for about 20 or 30 mins. I'm unfamiliar with the abbreviation but what is "UR" and is that any different than the raster brick I used in my conversion?you actually need a shielded brick aka cocktail brick, transformer on an UR brick is not magnetically shielded and the raster cocktail bricks are, unless you enjoy the rainbow distortions and in that case just go ahead and use the UR brick
Wonderful, thank you!UR = upright
CT = cocktail
CB = cabaret
CKPT = cockpit
YMMV = your mileage may vary
Is that copper band around the brick the shielding? If so, then the brick I just put in does have it.FWIW - for what it's worth ... my WL CT brick is shielded.![]()

Yes, the EMI shield is copper. Proximity of the magnetic field to the CRT is much worse in a cocktail than an upright.
Here's someone else's pretty pics.

So, I got this warlords cocktail,, monitor has massive burn in,, along with reduced Horizontal width on screen, & given where its burn in is located ,, must have been like that for years.
I'd like to try and swap out "the sanyo 100vac monitor assy". Its got a picture tube p/n 370HAB22 (With No swappable candidates exists)&(no definitive schematics exists)I changed all electrolytic caps as well.
I would like a compatible monitor before I start to check all board timing, I checked the clock , 12.096 MHZ. spot on. My limited experience, lots of theses early warlords had horizontal width problems?
SO, can I just swap output pins 12 and 14, on the power brick (037046-01 see attached), to change to 120ac ? ("ANDREW", mentioned this about swapping a couple of wires, turning working warlords CK. with 100vac Sanyo into a warlords with 120vac compatible monitor.
Also , Is the swapping of pin 12 (100vac) OUTPUT , to pin 14 (120vac) considered, changing to an UN isolated AC input for the monitor,, a NO-NO!..
or, how to tell if my replacement monitor (wells garnder) will fuction PROPERLY AND DOESN'T NEED A SAFETY ISOLATED TRANSFORMER or swapping of pins altogether. will run fine on just the 100vac?
"I could try comparing ac output voltages at pins 12 and then14,,,while, swapping the common lead from pin 10 and then to frame ground to see if "isolation" is functioning properly?
