WTB or WTS Tektronix 465

chrismh_somenumber
 

I have a 465 that, except for a blown HV multiplier (part 152-0552-00), works fine. The problem started while I was using it, so I know it works fine.

There is no display on the CRT and I've traced the problem to the -2450 supply. Following the troubleshooting procedures, I disconnected the anode lead and the dummy resistor in the HV supply and the -2450 came up. The manual's suggestion at that point is to replace the HV multiplier.

I was planning on selling this scope anyway so I'm hoping that someone on this list:

1. Wants a 465 that only needs a HV multiplier

2. Has the part I need and wants to sell it (part 152-0552-00)

Thanks,
Chris

Chris, I don't know the construction of the multiplier but perhaps it can be repaired.

I have a working 465 but it's got a few minor issues.? A parts unit might be nice if it's cheap enough.? I have a 465B parts unit; I wonder if it has the multiplier you need.

I am in Los Angeles.

Someone on the list has done some rebuilding of HV multipliers ...maybe it was for the 2213..the concept is pretty straight forward? electrically. basically caps and diodes. THe challenge is laying out and building (potting) one that doesn't arc when your done

Chris,

I checked the manual and the 465B uses the same multiplier.? So I could disassemble my parts unit and remove the multiplier.? I have no idea whether it is good, and it will probably be a bit of work to remove it.

Let me know what you think.

Bob

Bob,

Thank you for checking on that. Someone else offered me an unknown condition multiplier for cheap, so I accepted.

If that doesn't pan out, I may take you up on your offer, if it's not too late!

Thanks,
Chris
