Yamaha M70 Amp : Is this true ?...Warning of mylar capacitor being fire hazard

Well, this is interesting. The "trick" was really quite advanced voltage tracking power supply.

This isn't just a mod, but an entirely different power supply.

Also interesting, is that the Yamaha EEEngine and nuForce seem to use variants of this idea today.

Perhaps it is what accounts for some of the M-70 charm, and that of the a-560-760-960.

Of the many Yamaha Capacitor kits, I supply on ebay, the M70 is the only kit I supply that includes replacing this capacitor. 

Fact of the matter is, it is my advertisement the OP is talking about. 

I decide to include the mylar capacitor also, just as a favor as I knew this was a big issue, so may as well include that capacitor also, even though the kits were made to replace the electrolytics only. 

I find it funny that my inclusion of a free bee capacitor as a favor, turns into someone thinking they are being scammed!!, but that is the world. 

All the best from the greatcanadiannorthernstar. My kits are also on reverb.
