Indeed. Maybe I was just lucky to not get stuck witha huge stockpile of them, so I was free to select devices that best suited the task - and the 3055 rarely got a look in on that basis OR on bang-for-buck.
As always, YMMV.

Even better. I'll pay you 10% over shipping for the whole load. :)

My magnet says steel. The copper-slug '3055 items in my collection are the plastic-package gizmos that don't have that nice high 200C operating temperature limit.
A fair few of those suffered from HF instability, as in "I can hear you three megs up". Layout was everything, otherwise the only cure was to reduce the loop gain and to hell with the degradation in regulation.
Glad to be rid of both devices.

I've worked with 5V 1000A linear supplies built with them that were rock solid. Of course, that power supply was in a $250,000 piece of broadcast equipment.

I built several 5 to 17 volt high curent supplies biult from a 7805 and a bank of surplus 2N3055 about 30 years ago for two way radio repair benches. Stable and clean. I had to repair a started motor for one of my service trucks one day. It ran fine on one of those supplies.

Then yours are newer than mine.

I use ammonia to remove body oils from the keycaps. How are you going to use a cleaning cloth to clean between the keys without spending hours? I can clean a dozen at a time with my method.

Why remove the keycaps when there is no need?
I used to use Alka-Seltzer tablets to clean small knobs, when there was no ultrasonic cleaner available.

Useful onli for big, big screens. ;-)
That cloth is incredibly effective with finger grease. Also very useful if you are victim of friends and colleagues that have the need of pointing at the screen with oily fingers.
I only have two keyboards. :-)

Did you ever look under the keycaps?
I've used dish soap and a brush with long bristles. Well, first I blow out the dust and ashes with shop air, then scrub with dish soap, rinse with clear water, blow dry with shop air, and let it sit for a day. Works like a champ!

No need to, unless you type on the bottoms. :)

Ammonia is cheaper, and I can wait overnight. :)
