Lubuntu 17.10 4GB Core2Duo 1.4 GHz Laptop
Audacity 2.2.1 @384k samples/sec
Distribution release.

After recording and processing to restore old wornout tape there is clicks similar to a record with lots of dust at regular random times. See Att.
There are minor flat spots in the recording.

Am I pushing my old Laptop too fast eg the sample rate?

Try dropping the sample rate down to 44100 or 48000. Use whichever works for you best (they both have a frequency bandwidth that far exceeds old tape).
