content: Coming from your hands, in must be in near factory shape! I didn't know you also got the 2005A, pictures would help if you still want to potential buyers. Alas, I'm up to my ear in uV PSU but others would appreciate such a good beast.

content: That looks just beautiful. Beats the hell out of mine, into which some oafish boob drilled holes to fit oversized neonsCheap ones at that, as they too were burned out by the time I received the PSU.

content: It's a great supply. If I were in short supply of supplies I'd go for it.I have the version without the 10/20V switch, and nothing compares to how fast you can dial in a voltage. Great output too.
