content: Tek mainframe & modules still available, the HPs are all gone.Item 0: Agilent 66312A power supply, dead output, A$50SoldMy old good power supply from the lab at work, now has dead output (was set to 5v when that picture was taken). Service manuals for it are available, but another that I don't have time to fix.I'm finally getting to the end of a house move, and have decided to get rid of some repair projects it seems I'll never get to.Item 1: 4x HP/Agilent 66309D power supplies for repair A$200 for the lotSoldThese were bought as a parts lot many years ago, all four are physically in decent shape, (now) with knob & phoenix plugs present. I have a set of fault descriptions that I verified, although I think I may have done a board swap to make one unit work after that.Item 2: 1x HP E3631A for repair A$50SoldMy old main bench supply until it died in December 2018. Can't find my notes for this one, but I believe the fault was around the control processor, so possibly a parts unit.Item 3: Tektronix TM-500 series chassis & modules A$200 for the lot1x TM-503 chassis1x DC-504 counter module1x PS-501-1 power supply module1x DM-502 DMM module2x custom modules (see photo)1x SC-502 oscilloscope module - physical damage to connector, has physical but not electrical repair1x TM-515 chassis - physical damage to rails, will need repairItem 4: Magnepan MG-0.5/QR (pair) + MGCC-1 A$200An old pair of maggies, plus a nearly matching center speaker. They worked fine last I used, but have been sitting around for quite a few years.Somewhat off topic for this forum, but may as well list.I also have another HP linear supply that may be listed later, however it's stuck at work until my corporate overloads allow us in again.All available for pick up only in Ultimo, Sydney (right near the MSY) payment via Paypal, bank transfer or cash.

content: The notes on the 66309's are:Serial No: US39073090Repair Determination:• Claim: Channel 1 appears to be okay. Has voltage and current output.• Claim: Channel 2 has no output. Goes unregulated when output on is pressed.Serial No: US39072701• Claim: No display. The only thing that appears on display it 'shift' when pressed. Repair needed to eval for further problems.(My notes which I don't fully trust indicate that this one may be working now)Serial No: US39071033• The HP front panel unit• Claim: Unit has bad output on channel 1 and 2.Serial No: US39071461• Claim: Unit has no output. Both channels are inoperative.(My notes say this one may be fully dead, with an issue likely at the input transformer)
