3 of 5 controls were free. Bass & Selector-switch still frozen, hard.
Apply Kroil. 12 hours. Re-apply Kroil.

Which is why I use Kroil and don't waste my time on other products.

Using Kroil as cleaner/rinse would be wildly expensive! And of all the Dynaco products, the SCA 35 and ST 35 are amongst the lease amenable to going through a dishwasher. Between the cloth-lead transformers with open bells and fish-paper insulation and other issues, the risk is just too great - or that would have been my first choice in this case.
