Sorta like W. C. Field's comments on marriage ("Women are like elephants - I like looking at them but would not want to own one.")
I like the quote
.Apparently many of the Quads out there Have issues with sensitivity with either the EHT or leaking panels or have issues with dust ingression due to holes in the dust covers. The Panel I am doing first is a Bass panel that was replaced by Quad in the 80s so it should have been fine.... Then you take the panel apart and see that the technician must have been late for lunch or clock watching and wanted to go home on a Friday afternoon as maybe only 35% of the diaphram was covered with the conductive stuff. It was applied in wild streaks missing most of the bottom quarter of the panel which kind of explains why that panel was always a bit quite, I am amazed it worked at all personally, but apparently many are like this.
The good bit about the 1980s Quad service
was the fact that new treble panels were fitted and the new at the time protection circuit. The treble panels will have been coated as poorly as the bass one, but at least the stators are not burned as may are as they have been protected since with the protection circuit so when I rebuild them properly along with the other panels (already done the EHT) they should sing and hopefully be reliable for someone for years to come.
