hi, i have a pair of old mac 50-w2 mono blocks and one got sick tonight.
the first symptom was a rushing noise a few seconds after the amp was
turned on, much like being between channels with a old tube AM radio.
i powered it off and suspecting a tube swapped tubes with the working
amp.
problem satyed with the same amp - so not likely a tube.
i then swapped outputs to the speakers - problem stayed with the amp -
so not the speaker.
when i put it all back together and tried again, one of the output
tubes flashed blue and the fuse blew.
when i've had similar problems in the past, it's been a bad tube,
but it doesn't look like that this time.
thoughts?
Time to put that bad boy on the operating table and give it a proper
physical. (:)
