Hello, some months ago i get another Egret2, i know the seller changed the tube and chassis (swaped from a NAC) in the Egret2, then i have a MS9-29S tube (A68KJU96X) and MS9 29A chassis.
Well, after turn on the candy i can see how the screen shows the image with a green tint colour for 1-2 secs almost, after that the colours are displayed ok, no more green tint colour on screen. I thought this happen because the 29A chassis dont have autodegauss (tell that i noticed 29A is conected to the Egret2 video jamma conector without modifications, i mean that the jumper cable, that joins degauss circuit in Egret2 jamma conector is present like if a 29T was conected, if i´m right that jumper cable on conector should be released using a 29A chasis to add a manual switch instead that jumper cable)
Then, i get a 29T chassis from Japan, because i´ll want the autodegauss and no the 29A, well, at first 29T test i noticed that the Green tint still appeared on screen and this time not for 1-2 seconds, appear all the time, i had to move the Gain Green pot on Remote to adjust the colour to avoid the Green Tint on screen, after do that Green Tint appear on screen only for 1-2 secs after boot.
I tried also the 29T from the another Egret2 i have, same results, it seems Green tint appear at first Turn ON and need change the Green Gain pot on remote.
After those tests i reccapped and resoldered all the 29T and 29A, also i cleaned the tube to try see if something wrong in yoke, no changes, remains the Green boot screen after Turn on.
Also i recapped all the PSU
I thought that maybe that problem is normal because for some reason the tube turns on earlier and shows that green tint with the game intro displayed image that in anothers tubes should be displayed on black, seems like the tube turns on earlier than another tubes and happen that? All tests are done with an Atomiswave Base conected to jamma, in the another Egret2 tube (MS9 29T) this not happen, i mean the Green Tint colour on boot for 1-2 secs.
I remember that with 29A the Green Boot tint happen only for a 1-2 secs and after all colours displayed ok, i suppose this happen because the Green tint pot on chasis is adjusted to avoid the Green saturation always, like i did with 29T to avoid the Green tint saturation, but then, this tell me that the tube displays always a Green tint (not only in boot after turn on)? Why happen this? Could be related with something in tube Yoke?, a voltage problem?
Any help is welcome.
