The tants. in the 108SR to which I referred were used as coupling caps. between the (AM)Radio detector o/p and AF Preamps., and also between the tape preamps. and AF stages, so no high voltages or currents involved, but leaky coupling caps. obviously upset the bias on following transistor stages. Just another example of something not expected to last and be in use over 40 years after it was made, I guess!
