The component rivets inside the old tube chassis I am restoring were of soft brass and drilled out easily.
Now I am trying to replace two RCA jack plates (**) on the vertical rear plate of the chassis.
These are not accessible on the dimple side , inside of the chassis.
The outer side rivet heads are chrome plated brass, domed, and a lot harder.
There are six to remove. On two attempts the drill has started off centre , now the rivets are spinning.
I though I would ask here of anybody with rivet removal experience, before purchasing a small cut-off saw.
Thanks for any info.
(**) The RCA jack plates do not work with present day RCA plugs with 1/8 inch. 3.2 mm pins.
The jacks have a ceramic bushing with 4mm bore, and the spring contact is also oversized and does not contact.
A banana plug (4mm) dia, engages properly.
