[QUOTE="sercoe, post: 1011259, member: 15606"] Hi all As I use a Mk3 and a 160 to test valves, I like both instruments for different reasons. The 160 is portable and very solidly built. The mk3 has a greater range, eg negative grid volt to about -100V. Here is a link that describes all the Avos and their weaknesses: https://jacmusic.com/Tube-testers/Analog-Testers-Part1.html This guy also repairs these fine old instruments. Even that very rare meter can be repaired apparently. In future I will use a Roetest as it gives you the option to store all your measurements in a database, characteristic curves included. :thumbs: [/QUOTE]
