Just a follow-up. Thanks to Dave McGuire (thanks Dave!) I received a replacement polyester film cap today and replaced the old exploded paper film cap on the 1980 TRS-80 Model 4 floppy drive power supply! Haven’t tested it in the machine yet, but thought I’d share the process! Photos in the directory below: https://drive.google.com/drive/folders/1C_F28AXjqI8P7baLBs8Y5WPEwESNZMjl?usp... - Bob Shuster

While Dave searches for this, does anyone else maybe have one available? On the Model 4, it?s C21 on the Astec #AA11320 power board, 0.1?F, 250V AC, metalized. Spacing on the leads is about 18mm? I should probably replace it with a polyester version if available.

Until now! Power supply filter cap on a TRS-80 Model 4. So where do you guys go for parts? I?m not looking to stock up, just need some one-offs (probably the X caps.) Do you just go to Mouser or Digi-Key?
Mouser or DigiKey.
Does anyone have spares?
I have tens of thousands of capacitors here. What do you need?
