Yamaha Amps & Simple Killer Amp...
I've seen here and on other boards people recomending the Yamaha M series and MX series amps. Does anyone know what the difference between them might be? I've read about the mods here to the M-80's which sparked my interest in the Yamahas.

As a side note, I'm thinking about taking on a construction project. I've followed the Simple Killer Amp threads and seems like that would be something I'd be interested in building. Might anyone that has built one have any comparisons to commercially available products?

Hi Bian:
The finest amp Yamaha ever made is M4, stay away from Mx, and M series.

I have a M4 & C4 that are not putting out any audio, not sure of the history of the problem as they came from the curb:eek:
The bulbs that are not blown come on, what usually goes wrong with these beauties?

I took apart an old Yamaha receiver to recover parts from it - which I regret, it should have been repaired. But I noticed failed electrolytic caps on the main board, not power supply caps either. No other sign of fault but it would not have been possible to see the failed caps from a visual inspection without first removing them from the board. Hope this helps.

Thanks, I have every intention of getting it fixed, it is a work of 70's art that I can't wait to hear.....:)
