McIntosh mp 100 Phone Preamp Problem.... Blinking Red Power Button

Hello all,

 

Appreciate any potential help... I'm a little dismayed... 

I was testing out RCA interconnects on my McIntosh MP 100 preamp, and suddenly the green faceplate starts blinking about every second. After maybe a few minutes of this, just the reg light around the power button blinks about every second. 

 

No more power on! 

 

I looked into the manual, and I didn't find anything that would help. Any suggestions? Did I blow a fuse? Did I somehow kill my McIntosh mp 100 phono preamp?

 

Thanks

Richard

Maybe a dumb question, but was the Mcintosh powered up during the interconnect switch?

Yes, i think it was powered up when I made the switch. 

 

… was that it? 

 

The McIntosh tech asked the same question…. Saying I should make sure it is powered down when doing anything. If that is the case… such sensitive equipment….

I always power down before changing connections.  To me, it only increases bad possibilities to not do so.

That is a pretty nice phono stage.  Once repaired it should serve you well.  Good luck.
