TDS 520A 'parts only'


David Collier
 

Hi all,
Just acquired via Ebay. Front panel dirty; no fuses blown; one 10 ohm NTC current limiter and two voltage limiting diodes in the PSU needed replacing, also a handful of SMD electrolytics on three panels were around 6 ohms ESR. Replaced with 10u 50V and 47u 16 to 35V standard electrolytics from parts bin.
Finally switched on: result ALL checks passed and nice clear display!
Now all I need is a 500Mhz input connector.
