Blue ESR meter and tube equipment servicing

[BubblesTheFish]

Hi,

A few quick General Questions about the Blue ESR meter --

1) I can see where it is very useful for "modern" repairs of solid-state equipment, but do you find real value for tube-equipment repairs? (If so, to what extent). Sure - I can see where you might be working on an old tube tuner and want to check a few of the smaller electrolytics in-circuit, but can you REALLY find problems with the HV caps (400V+) that are more typical of tube equipment?

ie -- I guess what I am trying to determine is how much value an ESR meter has for a mostly tube-equipment technician. Would ~you~ find it a useful tool for tube-equip servicing?

2) To what extent would the ESR meter itself be damaged by dielectric adsorption? As you know, it is not uncommon for a cap, even discharged, to regenerate its voltage. Since you cannot test the cap with a discharge tool attached, I am wondering whether (a) dielectric adsorption could damage the meter, and (b) whether the regenerated voltage (even smaller amounts) would adversely affect the ESR meter reading? My understanding is that the Blue ESR has no ability to safely discharge the cap, and that seems like a limitation.

Thanks in advance,
BtF
