Hi Mike,
Thanks for your reply. The silver mica caps are still there (4000pf & 10000pf). I took them out and checked them for both capacitance and leakage and they’re fine. The other 2 caps on the oscillator board (0.1uf) were replaced by mustard type caps which I know perform well, and they replaced the original leaky caps. All the caps were leaky and a good idea to replace them I felt. I also checked for out of spec resistors and replaced as necessary. As Bill mentioned it might be a good idea to check the bias traps as due to a recap job the alignment might be out. I had to do the same procedure on my Revox G36!
I am unsure whether to tweak the equalisation pots as in the Ferrograph manual they strongly suggest not to touch these as they come out carefully set from the factory. However a bias adjustment is necessary I feel to ensure that the machines record well.
Thanks for the experience shared re caps!
