eico: 666; Tube & Transistor-Tester Deluxe

I have purchased an Eico 666,I am cleaning and testing this unit. I have read some modifications for this unit, diodes mounted to the meter leads. Would this be a good modification and can they be mounted to the wires other end away from the meter? Seems it would be easier then mounting directly to meter connections. Would there be any other mods to make for durability and reliability? All information would be appreciated. Richard

Richard, I'm having trouble adding a link so Google this: buying, restoring and calibrating an eico 666/667 You are looking for a document called restr666.txt and it usually comes up as the first hit. I'm not sure if you had seen this yet, but it's an excellent resource. Best, Rik w2rik
