Thanks, @atmasphere , I guess I am going a few extra miles then. I will worry no longer. Thanks again.

@mulveling , forgive me for my limited ability to understand electrical theory, but based on what you typed, assuming the applicable cap failed inside a tubed preamp, the output transformers of the tubed amp (assuming a tube amp was behind the pre) would still protect the speakers from DC voltage? |
@atmasphere , this is pretty much what I do now-a-days, but how much time should it take the preamp to stabilize? As far as understanding electrical theory, much beyond which wire goes to where is beyond me, but here is what I have: the separate power supply of my SLP-05 has two meters on it, and one is supposed to read "210 vdc nominal" but usually reads ibetween 230 to 240, and the other is supposed to read "60 mA dc nominal" and usually reads between 55 to 60. After turning the preamp section ’on’, it takes a couple of minutes for the meters to come up to within the paramters I just listed and then a couple of more minutes for a red light on the front panel to illuminate which theoretically means it is ready to play. (My amp has two switches on the front panel, one power switch I am assuming provides power to the four large ower caps; according to the manual "left and right bias voltage and high voltage" and the second switch is what gets the tubes glowing. After the preamp meters and red light say it, the preamp, is ready to go, I normally turn the first switch of the amp on, but then I usually wait about 20 to 30 minutes before turning the second switch on & lighting up the tubes.) Is my amp at risk the minute I hit that first switch, and would you think that I should wait longer on that? Thanks. |
