I just love the look on the roo's face after the bloke clocks him one. All kind of "What? That's not supposed to happen! I, I, I,... [speechless]".

--- End quote ---

Yeah, he looked just like my math teacher Mr Wilkes when I told him why I lied about losing my math book.  :-DD

What you didn't get to see was the part where the roo chased the guy down and launched him with both feet...  :P

3rd Scotch while cleaning up the shed = 5340A with Nixies  :palm:

I am blaming the cleaning as I found a 2U space free  :-DD

Must find the photo of my Mum in Bed in a Caravan when Mum Roo and Joey came in to say Hi  :o

I'm not familiar with a schaffner filter. Here's the primary side of the Inverter circuit. Does it have one?

--- End quote ---

Yes, it does, better check the brand printed on it.

Its the grey metallic box under the yellowed white tube on the left side.

I really didn't pay much attention to it but unless I'm having a brain fart I think it said Toshiba on it. I would have to go back and verify that.


--- Quote ---Also the plastic caps, as above photo those red boxes, if yours are transparent ones like below examples, replace them asap. Other wise they will pop too like these ...

I am well aware of those caps and their reputation for explosive failure. This 2465 has one, the other is a different type. I looked it over and the cracking normally seen on these caps is almost nil on this one. But I certainly agree it has to come out. I have a chart (attached) that originally came from the old Tek Yahoo Group outlining all the caps on the Inverter and Regulator boards. I used that chart to re-cap a 2465 DMS several years ago and it proved very valuable. I will use it to re-cap this 2465. I am also aware that the service manual has errors which can lead to incorrect placement of caps resulting in magic smoke.  I avoid that issue by doing one cap at a time...matching value, voltage, and polarity. It takes longer but it results in an accurate rebuild. The 2465 DMS powered up fine first try after it's rebuild.

That is one thing I'm afraid I can't help you with. My one spare is already in service. :-//

Oh, lookie here... it appears a suitable replacement is still available; a fellow found one and posted about it here on eevblog. You may wanna try and find that switch on DigiKey since Mouser shows them still "On Order".

Thanks for the lead. It turns out DigiKey has it in stock. I'm going to put in an order.  :-+


--- Quote ---Also... I stumbled across this recap kit while looking for that switch; it seems a bit expensive, unless you count your time tracking all the parts down as worth more than minimum wage. ;)


Cheers,

That rebuild kit looks interesting but I think his price is a little high.

bd139:
Just a point on the EMI filters on these. The little silver box actually contains 2/3 RIFA X2 capacitors and a common mode choke usually. RIFAs are pretty bad on their own but when you put them inside a pipe bomb, interesting things happen. We had one much newer than that in a SAN power supply and it blew its load all over the inside of the unit. I have a photo somewhere in the office I will dig out but it was a right mess.
