Never managed to find a set of his vids at a price that I liked and then gave up trying.
FWIW, the podcasts are divided up along the lines of his videos (e.g. Basic Video Game Troubleshooting, Monitors 1 and Monitors 2, X-Y Monitors, Basic Electronics, Semiconductors, etc ) and the total run times seem to add up roughly to the tapes.
For example, the podcasts for Basic Video Game Troubleshooting run a total of 77 minutes.
I watched the series on Linear Power Supplies last night (learned a lot, including the fact that my sister-in-law likes the 80s Randy Fromm look

) and it was a complete run (including the opening and closing "credits").
