I got it on ebay for $50 with the original box and in mint conditionThey are an excellent preamplifier with little to criticise about the design. What I love about them is the complete left/right separate power supplies right back to the transformer and very careful layout.
The ALPs bowden cable linked switches can get noisy/intermittent in their old age and it is a big job to properly fix. (I'll post up a link to yesterday's rainy day Rotel project).

How do you feel about replacing the op amp 5534 for this
OPA-604 biased with a FET transistor into class A? that the mods that people from the fm tuner group does to the tuner 990BX
what about the 2134 op amp ?
When you need high instantaneous power you need high voltage specced transistors. I think at the time there was not much choice.Interesting Don, thanks for digging in the back shed of your brain for me. So they were only a 3.5A Ic rated transistor, massively paralleled. High voltage, lowish current, lowish selected gain and massively stacked. I think I prefer the modern way...
I remember this stuff now. It was in the Titanium Series of Yamaha. Very nice gear. I sold it when it was new and it was flying off the shelves because peeps loved the titanium finish. It's a nice amp, not heavy duty like some but for home use it's ample and should sound justtt fine.Is the yamaha MX-55 any good ?
I found a Yamaha MX-55, I like the specs for distortion, the power is not that bad
You should test those, what do you make of the specs ?
I am going to use it as a 2 channel amp
It's interesting that in Canada the titanium finish was very popular and we depleted the supply. Staff was buying it too and customers where getting into it. It was like the fancy woodgrain MB Quart speakers that we got huge amounts of inventory of. It took a few weeks and then the people started coming in and buying it. What a visual combo with titanium Yamaha with some African wood or other exotics finish for the speakers. I really dug the titanium stuff.when Yamaha was throwing out all the Ti coloured gear
