My SA-260 power transformer runs pretty hot, too. Mine had many of the e-lytics replaced (underneath) already when I bought it. I didn't check if all had been replaced.Perhaps it runs fairly hot normally? I can keep my hand on it for only about five seconds.

Yes, mine is painful to touch too. I have no idea what normal in this amp is. In other amps I've owned, that's too hot and usually a sign that one or more cap isn't doing its job.
I have set mine up to run on 117 volts and I use a variac with it.I am sorry I failed to mention this.
I do this on pretty much all tube amps except homebuilts where I have control over PS design. Most old amp run nice and cool at 115vac.
The amp produces plenty of heat but I can not get to it right now to check. It is in rotation but not able to be checked right now.Sorry
I just put my ammeter in line with the power transformer and idled the amp on my test bench for 3.5 hours. The meter stayed at 1.64 amps the entire time. The power transformer was quite hot, but was not drawing excessive current, so I guess it just runs this way normally.I'm wondering whether this amp might be a good candidate for keeping a whisper fan running on it?
Any thoughts?
