thanks, the wonky pots are hopeless unless there is something i don't understand about coarse vs fine adjustment but i doubt it. 1st pass i will try to get them out and deconstruct without breaking

Is it just me or is the service manual for a 2221a scope next to impossible to find? I have been searching google all evening and have only found the 2221 service manuals for the 60 MHz scope and not

It's in the dictionary: 'discreetly cautious'. 'Wary' is 'marked by keen caution'. Not the same thing. Interesting article, although the author has some stylistic issues. The attempt to attach one

yep thats them. is there something more reliable to replace them with or should i stick to tants? phil yeah, can't complain :-)

i took a pic. i'll send it to your personal email. i see know easy way to attach a pic to these replies. i have 3 brown blob "dipped" tants for C7196, C7197 and C7288. i forget exactly which of these

If we're looking right above the power switch, I have 3 ea 15 uF @ 20 V tants. Looks like they are decoupling for +/- 8 & +5, so 20 V wasn't too close. I dunno. They die. Even with a couple bad tants,

thanks...i'll check it out. it does not seem right but i will revisit. phil

Phil, If I recall correctly, the 465B has a dual rate horizontal position control to give finer resolution when the sweep is magnified. This can seem like play in the control. --John Gord

For the record- tried resistor to the ring connection, was only able to get 10x functionality on the 5D10. Jamie

Which cap are we talking about? I'll slide the skin off of mine and see what it has in it. The pic in the manual almost looks like a wet tant. Those weren't real commonly used. -ls- "pdxareaid"

yeah, tantalum innards leaking out occurred to me but it sure looked like solder. what you say makes more sense. i never looked up tantalum construction but i understand they are electrolytic. i will

Good tip on the manuals from artek- my friend (the owner of the 5116 & 5D10 I'm working on) has them and they've been helpful in understanding the scope and plugins better. I'm sure when the time

Good job you found it, may have taken a while- good eye. Sent on the TELUS Mobility network with BlackBerry

Phil -- just a couple things -- you should probably replace that tant anyway. What looks like solder probably came from inside it. And the good news: .2 is the normal minimum on the 10-turn DTM pot

that is: So, not a very exciting fix but so far i have a nice working 465B but i'm NOT quite sure why :-o ok...i'm done. :-)

sorry about the voltage ripple table. it looked a lot prettier when i created it.

hi gerry, i think the problem is bigger than your email. several members have been spoofed...look at the "hello" posts...they are from several different members. phil ps. your 465 seeing the light?

i'm not sure of the best way to post this followup for all previous responders see. so, i'm replying to my original post... i spent some quality time with the new toy today. i guess it just needed

Thank you, sir!
