I'm having some problems with my MV-55 and was hoping that some of the expertise here might help provide a solution. I've documented the issue and the troubleshooting steps I've undertaken as best as I could below.
Below I refer to the left and right channels as being the left and right speakers when facing the system.
Original Issue: No sound out of the right channel.
Troubleshooting Steps Taken:
- Swapped Sources: Switched between various input sources to rule out any issues with a particular source, but the right channel remained silent.
- Swapped Left and Right Inputs from Pre-Amp: Exchanged the cables from the left and right inputs to make sure the issue wasn't with the pre-amp. The right channel remained silent.[
- Swapped Input Tubes Between Left and Right Channels: no sound from the right channel while the left continued to perform normally
- Swapped Output Tubes Between Left and Right Channels:
- V5 output tube brightness increased
- Shortly thereafter the "Fuse out" light came on for the left channel so presumably the fuse blew.
- The "Fuse out" light is not illuminated for the right channel.
Any advice on how to approach this or suggestions for additional troubleshooting would be immensely helpful.
Thank you for your time and assistance!
