  1. AR-II Question

    That brown stuff was adhesive to keep the capacitors in place so that they don't wobble during transport and break their leads. This is done on the big caps since they have a lot of mass. Fyi, I didn't know this either and went through the same thought process that it seems you are.. and when I...
  2. Newbie from the NorthBay

    Welcome! You might already know, but there is a big arcade event each year in the Bay Area : https://caextreme.org/
  3. Hello and help needed in San Francisco

    Welcome! As an fyi, this site also has local forums. You have to have set your city in the main klov web site to get access to them though. I didn’t know this for many months. The reason I bring this up, is that you can do a search there. I remember seeing posts about some guy in Vallejo that...
  4. so what did u do with your games today?

    Did my first ever monitor "repair." Did some work on my Multi-Williams... the red signal was dropping, but would come back if the cabinet was moved (or bumped on the side, Fonzy style). I had previously reseated the connector, but it didn't help. I pulled the chassis and reflowed the pins on...
  5. CRT workstation suggestions

    But was the reactor grounded?
  6. CRT workstation suggestions

    You seem to be stating, and contradicting the earlier advice in this thread, to keep the isolation transformer floating for the same reason that the eevblog video is saying. Am I understating you correctly? And if so, is there any condition or use case to have the isolation transformer grounded...
  7. CRT workstation suggestions

    I have seen a bunch of videos like that too. I think they are targeting different use cases for issolation than is used for monitors, maybe... (To be honest, I'm not sure why you need to have an isolated supply for the monitor) But.. the use case in the videos I have seen that advocate removing...
  8. Spy Hunter Cockpit / Sit down Restoration

    This might be a dumb idea, but could you just weld (or jbweld) a washer of roughly the same diameter on top? I know it's hacky.. but if it works?
  9. Warehouse and game collection photos

    Sick. Is this a shop for an arcade route?
  10. Let's design some POKEY replacements

    +1 This shit is hard and setbacks are part of the process with something of this complexity. I admire your grit. And as ArcadeTechGW said, you clearly have the knowledge and skills. Hang in there :)
  11. Let's design some POKEY replacements

    Ah, ok.. the comments are what made me think it was part of something larger. (There is a disassembly out there that I saw once, but now can't quickly find again.)
  12. Let's design some POKEY replacements

    Do you have a link to the rest of the disassembled code?
  13. Still looking for a Black Widow in in Az, So Cal or Vegas.

    I saw the one I was thinking of again. It's not in an original cab though: https://ventura.craigslist.org/vgm/d/simi-valley-black-widow-arcade-video/7796617845.html
  14. Soldering skills (lacking) for small holes - how to

    All of this... and this might be obvious from the above, but you can also use the soldering iron and a heat gun/hot-air at the same time. I sometimes do that with a soldering iron, but when desoldering through hole parts, I'll turn the board sideways and use desoldering gun on one side and the...
  15. Soldering skills (lacking) for small holes - how to

    Wait. what? I only have one, and it's grounded, but what's the issue if one isn't? And whatever the issue is, is it only an issue if they are on the same power circuit? What if one is floating/battery powered?
