I know it sounds counter productive, but add solder to the dip legs your trying to remove. Its then easier to desolder the pins. It's also a lot easier to remove the solder if you pre heat and continue to heat with your hot air as you desolder with your hakko. You have to be careful with the...

It's not the output voltages that are the issue. The problem is that the monitors main pcb is dependent on that flyback being correct to produce those voltages.. For example... The first (and easiest thing to determine) are the flyback pinouts the same? Then, you get into the real issues. The...

Hate to be the barer of bad news. It's not possible. Unless those two monitor pcbs were exactly the same I wouldn't even think about trying it. Flybacks don't just supply high voltage (although it is their main purpose). Depending on the flyback they have multiple windings supplying grid and...

Another saved from the dead pile! I'll be using that case tab image to fix one of my machines! Thanks zzj!

The windings on the flyback/ hv transformer short internally. The short causes heat that can melt the housing as well as the expansion of gasses. It can either crack or burn a hole through the plastic housing. They're usually toast at this point.

You could try some high voltage putty or carona dope, but it's a band aid if it works. The hole was most likely caused by a short and you're going to have to find another hv transformer. If you can't source an nos/pulled one your best/cheapest bet is to find a non working monitor and hope the...

I've had to lubricate the bearings on a number of seagate drives. I would, however, recommend backing up your drive. Especially since you opened it. You can use a modern scsi drive replacement solution ( zuluscsi or bluescsi) in initiator mode to copy/backup the drive to an SD card. That way...

As croissantking said, your sound issue might be something as simple as a dirty audio jack. I would cover all the simple stuff first and trace your way back. Looking at your pics, another issue I see is that some of your caps aren't soldered to the pads. Are you using enough flux? Make sure...

Nice. Congrats!

Dead mac scrolls was written before all these caps went bad. That's a common issue with monitors, and it's usually caused by a bad cap. When was it last capped?

And so, the battle begins... This beast has parts... LOTS of parts.

Yeah... I was just about to say the same. Se tubes run at a super low bias on g1 from what I've seen in the past (-36, I believe). I was using a sencore cr3000 to check out a bunch of tubes and had lots of fun figuring out their settings / pinouts (the pinouts I found in references were...

When you say your doner tubes are kinda compatible how far off is your heater voltage? I believe the se heater voltage is 12v (which threw me at first since most run around 6.3v). If your heater voltages dont match, you oght be having issues with the gun emmisions.. Also, just to confirm...

Not sure its worth all the work, but you could design a transposer to change the orientation/position of the aforementioned upgrade - i.e. socket booster (see pic). Not exactly this... I'm just using the picture to convey the thought process., i'd design something like it to change the socket...

Yeah...I've never seen anything like it before. I haven't had a chance to boot it yet (wanted to go through p/s before power up). Wanted to see if anyone had any insight into it first. The joystick and buttons just go through the 16 pin dip gameport, so they should work fine. I believe the...

I was given this Frankenstein this weekend, and can't seem to find anything on it. It seems to be something made videx. Its a strange beast. Besides the obvious controls on the cover, It also has some other weird stuff inside. It has a videx 40/80 column card in it (not weird), but it has an...

That looks an awful lot like a molex micro fit connector. This might not be the exact one, but will get you in the ball park. https://www.molex.com/en-us/products/part-detail/436450400
