Label on the insife of the cabinet shows high voltage horizontal sweep module as 9-454. If that's not it, let me know.

I had this module, but used the last one I had in a set that sat unused for almost 25 years. The CRT tested like new, so in went the module. Set is working great. Sorry I can't help you. I also checked my used stash.

I found CR3205. I should hang off that to check for 150 vdc at c of hot? What is c of hot? Sorry, just can't think straight. Also, i can't locate CR3473. Wanted to mention a blue wire coming down from the yoke with a red wire has burned at the end where it plugs onto the HV board. red is fine. trying to test today and smelled burning.

Yes for 150V use anode of CR3205 as ground.
CR3473 on main board ( 9-214 ) ??? Left of main filter cap & a stand-up power resistor. Use cold ground for that. Fix zorched yoke wire now, if you are lucky its causing shut-down. 73 & merry Christmas Zeno

I found CR3473. Clipped off that and metal corner mount of crt and got from 0 to 4 but realized i had left the ribbon cable off the main board that runs up to the crt board. when i put that back on, meter never went up at all. as for the blue yoke wire, i had to relocate that on up the trace to another location on the back side of the HV board as it had burned the board around that immediate area and the pin where the cable used to mount on had fell off. the smell i get now is just from the instance where i first turn the set on. it sparks there at the burnt area one second. what next?

Blue wire is low end of yoke. If you havent cut out all
the burned PCB & replace etch with wire. Also remove the burned connector & be sure the red wire is clean. Path of yoke is through LX3262 lin coil, LX3261 width coil, C3261 coupling cap, then TX3251 pin transformer. Also give the board a real good visual for bad PC cons etc. 73 Zeno
