content: The input board on my venerable HP 5335A has gone tits up so I decided to part out the unit since shipping costs are quite high for a large heavy unit. Besides the busted input board, A channel is broken and its probably an old op amp, everything else works. It has no options. So what I do have is:A4 Main Logic Board (power button cap has snapped off but will be included)A5 Display/Keyboard and front panel.A2 Amplifier Support boardA1 Power Supply board.Rear Panel with transformer and IEC input.A7 HP-IB board with A14 rear connector boardFront FilterA6 Rear Panel board.Frame and panels.Shipping is from Canada so shoot me an offer on the parts you need.

Alternatively, I could sell you the busted input board, which also has lots of the switches on it but they are push on/ push off rather than momentary.

content: I have a 5335A that's missing the button for the power switch, so I have to keep powering it up with a pen. Do you happen to still have that button?

content: That's a common problem and mine was also busted. Unfortunately, it was sold with the CPU board, sorry.

content: I don't suppose your HP 5335A had rackmount brackets/handles?It seems to be ridiculously hard to find 4U mounting kits for HP gear. Other sizes come up fairly often on ebay, but 4U are like hens teeth.Seehttp://everist.org/HP_notes/Parts_I_need.htm

content: I've almost certainly got the brackets but not the handles.I suspect that postage would be prohibitive however if you're interested then let me know.

Just one?The frustrating thing is, the brackets to fit with handles are different from plain brackets. So if I buy plain brackets, I can't later add handles if I find them.

content: I have no idea if a transplant is possible but it sounds like your board is a newer version so most likely not.
