I recently got one of these off the bay that didn't run.
I stripped it down, cleaned it, soaked the whole thing in wd 40, re-greased the drive with lithium grease, lubed the motor with 3 in one and put it back together with original wiring and e unit untouched.
This is, bar none, the best old turbine I have. Starts up every time with minimal voltage...crawls at slow speed until it stalls on voltage-starved sections of track (dirty...my bad) and beats all the later model turbines with single worm drive I have...because it just RUNS!
I have a question about scale on these turbines...they look to be s scale on o gauge spacing. Is that a fair statement?
