Hi everyone, I'm reviving this thread because I just bought a NAD 214 amp and I have a few questions about what was discussed. Please bear with me as I am a bit of an amp N00b.

I searched for replacement power supply caps and found these:

UVY1J472MRD Nichicon | Mouser

63V, 105C, 4700uF, and I confirmed that the size is ideal. Is there anything I've overlooked about these capacitors? Are they too cheap to be worth installing?

Second, with regard to the input capacitors, is the problem merely the quality of the stock capacitor? Should I replace it with a higher quality 1mfd cap or should I change it to a capacitor of greater value than 1mfd?

Third, looking over the schematic I am unable to identify the muting transistors. Are they TH101/102 "thermal breakers?"

Lastly, I'm also curious about the controversial shunt over the transformer. Does anyone have any insight to the benefits or drawbacks to this shunt?
