If you’re lucky, the Yamaha P2200 with meters, P2201 without are quite good but may need some refurbishment. These don’t have speaker protection though.
Same goes for the later PC2002/PC2002M (metered) which do have speaker protection and in my experience are pretty robust if properly working. Fully refurbished they are almost bulletproof.
Each sounds very smooth with plenty of power reserve, most were probably used in studio support applications or sound and theater applications so be sure to get a service and operational history before any purchase. Many other later Yamaha professional power amps are also nice sleepers in power, sound, and size, having gotten smaller and lighter with fan cooling.
All our recommendations should include photos because besides great sound, big amps should also look great too!
