Agilent E3615A, my eleventh benchtop power supply.
That's some serious TEA
I probably have a similar ammount of E361xAs, as you can never have enough DMMs, PSUs and oscilloscopes (and to a lesser degree all other test gear
). These E361xAs are great little PSUs and I quite often had situations where I needed like -15V, -5V, +5V, +15V, +30V and +150V to test some gear, so I used like 8 E361xAs to power it, (+150V from 3x E3617A in series)
