Pioneer SA-900 Stereo Amplifiers as a matched Pair

I bought a large lot of Vintage and these 2 matching Amps were in there. In this picture, the bottom amp powers on and sounds very nice. The Tape Monitor switch needs to have the spring put back in place.  I have Deoxit sprayed each of the pots, and there is no crackling or static.  The Top Amp blows the Left channel fuse immediately and could be repaired or used for parts. A rarity to find 2 like this.  Cosmetically nicer than the others i have seen listed. I have not taken these apart, Tested values or otherwise had them apart, They are sold As Is and will be Packed and shipped well. International shipping would have to be discussed before. Thanks for looking!
