all four driver transistors tested bad. once the first tested bad, I found two matched pair for 24 bucks shipped on eBay. will drill out the old transistors so I have some spare heat sinks.
ordered a bunch of 1r 5 watt resistors, 10 2n3055 (not much more than 5 so why not?). guess I need to invest in a 100w bulb and junction box. I'm certain I have a spare socket somewhere (updating a house with original fixtures from the 50s and 60s...)
so now again we wait for parts. weekend visiting the in-laws shall be spent checking usps tracking
