aftermarket fuse location

Far as I can tell, QSA greater. Others lesser.

MC, you have lost track of the question 

OP In your Pass is there a fuse on the other side of the power supply?

Pass is one of those amps. It has such a great power supply, not a lot of room for improvement. Krell and Ampzila, Threshold, huge PS and TO ME the AC fuse and the PC other than being big enough, didn't make that big of a difference.. Ampzila the PC was cold welded in..

The +  side of the rail for sure. Threshold had 2 fuses one on both + rails of the amp. I used gold plated Acme back then.. There was no SR that I knew of..

A lot of speakers had inline fuses too. I bypassed all the mid driver fuses in Infinity and  Acme fuses for the highs.. 1990s. I still have one set of Infinities set up that way.. RSIIbs.

Fuses count especially in the sound path or after the Power supply..

My Mac preamps have a few inside the MX series. Inside yes, the AC fuse no.. Cary is the same way.. The PC on the Cary makes a huge difference but the AC fuse didn't..  After the PS it sure did though. That is a weird one.. ALL SR fuses though..

Regards

@oldhvymec, thx....the only fuse that i am aware of in the PASS X250.8 is within the IEC....I swapped to the SR Orange, but didnt frankly notice much
