If you have a voltmeter with a fine enough scale to read the output voltages on both the preamp and amp, and a cd with a sine wave test tone, you can play the cd, then step the gain switch on the pre, and measure the right channel output, then the left channel output voltage from the preamp, then the same outputs from the amp. Each set should step in a reasonably linear fashion. That should allow you to distinguish the amp from the pre. It also helps if you know what the full scale output voltages in each case should be.
Help/Major Problem
I have a Aleph-3 amp and a Rogue 99 pre with phono.
I played the system all last eve. with no problems.
Tonight I fired it up and nothing!
All seems fine except no sound.Only a muted signal(music) when I turn the pre way up.I can see the line stage tubes through the cover of the 99 and they are lit up.This problem is with phono,CD and tuner.I have checked all I.C.'s and P.C.'s All check out fine.
What the hell could be the problem?
