Cover frame, with nice "hold in place when loosend" screws, I like that

The first thing to catch your eye is that massive transformer. Expected, since this is a linear supply.

Heat sink + the reason why this sounds like a 747 taking off..

Some beefy capacitors, sorry not the best pic.

Weee, a LM317t + a LM337

Hmm..

Some power resistors, looks like current sense to me ?!

Now, that's a REAL power switch, not some soft latching rubbish

Mains input / fuse / tab select (i think it's capable of 120v as well as 230v) And that 747 exhaust again ... -.-

That's a thing of beauty, a joy forever

As a well known person would say

Hmm, yup.

Wonder why they didn't use 105c caps, but then again they are all still fine..

Looks like that insert is changeable to set it to 120v ?
![](http://ec-projects.com/billeder/hp_e3632a/17.jpg)
That's a nice fuse holder!
![](http://ec-projects.com/billeder/hp_e3632a/18.jpg)
Ay, screw that..
![](http://ec-projects.com/billeder/hp_e3632a/19.jpg)
And YAY, still works
![Wink ;)](https://www.eevblog.com/forum/Smileys/default/wink.gif)
Set to 3A and spot on +- 0.1%
![](http://ec-projects.com/billeder/hp_e3632a/20.jpg)
Set to 10V, spot on.
![](http://ec-projects.com/billeder/hp_e3632a/21.jpg)
Set to 10V, measures 10.002 I'd call that a pass.
![](http://ec-projects.com/billeder/hp_e3632a/22.jpg)
Set to 3A, 3.006 ... Think i could live with that
