Nice pair of Vintage W5M Mono block HiFi tube power amps. These were my main amps for a few years after they were fully rebuilt. 30 watts per channel (amp). Cosmetically and electronically excellent and ready to run. These are not full of cheap Russian tubes, but have nice mostly old USA tubes and sound amazing.
These are 6L6 based Williamson style amps, and each uses a pair of 12AU7's in the preamp and driver stages, and a 5R4 tube rectifier. I installed a pilot light in one of them. One has the larger "old" style output transformer, and one has the "new" type. Both are Peerless of course. Some guys say the older larger one has better bass, while some guys say the newer one has special nickel plated laminates and sounds even better with more "clarity".
Read about them on the interweb. I couldn't tell the difference in everyday use as differences in room. Will have more of an impact, but suit yourself. Any difference is very subtle if even detectable, (and I used large Altec 604-8G studio monitor speakers).
