NOTE: Niobium Oxide capacitors have a 20% voltage derating which means if you buy a 10V rated capacitor, you can safely put up to a constant 8V on them without worry.
🛒 BUY
• Niobium Oxide Capacitors I used (Mouser): bit.ly/2Bp18WO
• Torx T15 with LONG neck (Amazon US): amzn.to/2ScAskx
• Bulldog Clip (helpful to pry off back case): amzn.to/2H7lIhF
• Soldering iron with °F-only LCD & Solder Kit (80W, cheap!): amzn.to/36BYi0K
or
• Soldering Station (120W, ESD safe): amzn.to/30g1Frt
or
• HAKKO (Japanese) Soldering Station (70W ceramic core): amzn.to/2YvIo42
• Solder (Leaded Rosin Core 1.6mm): amzn.to/3IGuxxm
🤓 USEFUL TOOL for Super-Geeks:
• DE-5000 Handheld LCR Meter (Amazon US): amzn.to/2ScttJz
The absolute best handheld meter to check the ESR of capacitors. That 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.).
💵 NOTE: Your price on Amazon (US only) is the same even if you don't click the "amzn.to" Affiliate links above, but if you do kindly click and purchase within 24 hours, Amazon may pay me a small commission on all qualifying items in your Cart (even items not linked above).
