Hello all, Have a 7904A, low SN, 1982, stored for decades.
Usual cleaning of switches, contrlols, the CRT, bright and in focus.
But all surfaces, PCB, PS, HV, CRT are coated with dust.
Suggest I vacuum with brush nozzle, finish with compressed air? Which is better?
Am Wary of Air, Vacuum ESD, damage,
So, should use Metal nozzles , earthed?
Many thanks, Have an absolutely fantastic day
Jon
