🛠 TOOLS:
• Plastic TV alignment tools: https://amzn.to/2Scykul
For making CRT adjustments on the white-covered side of the analog board. NEVER use metal! It must be ALL PLASTIC!
• Torx T15 with LONG neck: https://amzn.to/2ScAskx
• Bulldog Clip (helpful to pry off back case): https://amzn.to/2H7lIhF
• Phillips (+) head screw driver
• Discharge tool or flat-head screwdriver with a wire with alligator clips, for discharging the CRT -- ALWAYS done with the power off and power cord disconnected!
• Soldering iron with °F-only LCD & Solder Kit (80W, cheap!): https://amzn.to/36BYi0K
or
• Soldering Station (120W, ESD safe): https://amzn.to/30g1Frt
or
• HAKKO (Japanese) Soldering Station (70W ceramic core): https://amzn.to/2YvIo42
• Solder (Leaded Rosin Core 0.82mm): https://amzn.to/3GzJbVl
• Desoldering wick (Amazon US): https://amzn.to/3iMAnA5
💁♂️TIP: Set soldering iron temperature to 350°C. Don't use lead-free solder.
• 99% ISO Alcohol (Spray Bottle!): https://amzn.to/3ae4fG6
• 99% ISO Alcohol: https://amzn.to/3NoFkxN
• 99% ISO Alcohol: https://amzn.to/2YsK8v3
💁♂️3 alcohol choices because it's often out of stock.
• Voltmeter (Cheap!): https://amzn.to/2H1S7Ge
• Hot-Glue Gun & sticks: https://amzn.to/39hBfav
• Heat gun or very strong hair dryer that can melt hot glue, so you can remove some of the stock capacitors more easily after desoldering them -- some are hot-glued.
• Used toothbrush for scrubbing away the flux after you finish soldering in all your replacement capacitors. You can also use the opposite end of a toothbrush if you need to make adjustments on the Yoke as shown in my video.
• Swabs, for dipping in the alcohol if you need to clean up any spilled electrolyte from old, leaking capacitors.
• Rubber gloves (or any electrically insulated gloves) if you need to make adjustments around the CRT Yoke, especially with the power switched on.
🤓 USEFUL TOOL for Super-Geeks:
• DE-5000 Handheld LCR Meter (Amazon US): https://amzn.to/2ScttJz
The absolute best handheld meter to check the ESR of capacitors. Amazon link comes with all 3 accessories: TL-21, TL-22 & TL-23. If you buy this to check your caps, feel free to post your ESR measurements of the Analog Board caps in the Comments section, and be sure to let me know which Frequency you used -- (e.g., 120Hz, 1kHz, etc.).
MENTIONED IN MY VIDEO:
• Capacitor List (Mouser Cart): https://bit.ly/37metyA
⚠️ If you choose your own capacitors, ensure the Lead Spacing matches the Analog Board holes. All other caps in my Mouser list sit flush with the board. Carefully consider the Height of your caps so you don't choose caps so tall they stick out and touch the CRT.
• Replacement connector pair for P1 is sold on Mouser:

19-09-1049: https://bit.ly/2w0DXTC
Gold Terminals: https://bit.ly/3GHLwgF
Standard Terminals: https://bit.ly/3oESSey
Product photo on Mouser is wrong but Description clarifies that there are "4 Positions." I bought the 2 connectors & gold terminals.
• SilenX IXP-34-16 60x25mm fan has been discontinued. Get this Noctua Fan instead:
