I have a 1772 and it's running well on the original capacitors. I have not found it necessary to change any tantalum caps yet, although I've had to change one or two in my MA1720 driver.
The obvious thing to do is to sort out the 34 meg first.
I found that if the loops were wrong my set didn't go into mute mode but just got wrong indication of the frequency received. I have not had too many problems with mine I'm relieved to say.
I have had one or two problems with those slider switches. Mine were fixed with switch cleaner. They are available but not always easy to find.
