ghd4 2b in real time

Kev if you lay the 2 housings beside themselves and pass the appropriate size screwdriver through the 4 hinge pin holes the housings will be stable and remain flat while you work on it. Why did the resistor blow? My opinion is it's a supplier issue, 99.99% of the R8/R11 resistors that blow are base colour blue, the original base colour brown ones (in 50 ohm) almost never blow. However if there is a swivel connection problem (like the ones that took the obsolete Type 2 cable) then the brown ones will fail just as easily. Same goes for Cloud9 R31 & R32 under the switch, blue 50 ohm resistors dropped like flies, never saw a burnt out brown one.

in principle yes but on ghd4&5 you would need to use the bush, both blue and brown on paper should be fine but the brown has a high vmax so is more tolerant, bottom line its a voltage spike that takes them out either bad connection in swivel joint or switch or even customers bad mains supply. I feel more confident in brown
