Nenad Filipovic If you are interested I have some working units available for sale. Contact me off list for details. Craig

Oran, Thanks for starting this discussion. Here are the values you were asking about. When everything is connected, what voltages do you see: At 15V TP. 1.675vdc At the emitter of Q1546. 1.683vdc At t

Got a 465 that was somewhat functional but no trace with blown F1419. Went thru Groupsio file library and replaced the C1419 and that got the signal trace. Reviewed the Power supply and here are the o

Jared, My thought is the CRT Grid Bias calibration needs to be done. Craig

Jon, Static precautions need to be followed when handling. I’ve heard about cleaning the hybrid mating surfaces with the iso alcohol, but personally never done it to solve any issue. Why would you hav

Jon, If you look at the hybrid you will notice one corner has an angle in the heat sink mold. This has to match the base you are reinstalling it it as it has an angle also. Review this before removing

Dennis, Received book, guess just have to have extra patience when dealing with the Postal Service. Thank you for all of your extra effort. Eric, yes we are definitely in the same county. I’m glad to

Well I guess I won’t be receiving my book. That seems ridiculous that it’s not moving. There must be another issue. Maybe need to file a claim with USPS. Craig

I don't dispute the issues you are experiencing with mail delivery but it is not like this . Dennis Not that it matters but my latest Media Mail experience is I shipped a book to Southern California D

Larry is there a chance that there might be a purchase of the Rotary switch as a group purchase from DigiKey or all parts sourced up to the individuals. Craig

To clarify, when you say "jitter" I'm concluding that you mean the entire trace is randomly jumping in the vertical only? Your signal is triggering and the horizontal sweep is stable? Dave, Thank you

Jeff Dutky, Thank you for your intrest. Went thru the readings as you described ahead of vertical switching TP364, TP374 and after vertical switching TP322, TP324 and made comparisons, I see no jitter

Dealing with a 465 scope that is having a condition on CH1 that the trace has a slight jitter to it. Less than .1 but it is annoying to me. Is visible when a signal is displayed or when the Attenuator

This a a repost of Chuck Harris description of a 2445b to 2465b hack job. Maybe this will help you find out if you are dealing with a true 2465B. This information was obtained by searching Tektronix 2

Jared, I should be able to get these for you. Let me know what is appropriate for you. Craig

I would suggest that you disassemble it again remove the option rack and boot the scope without the option rack assembly. Yes you will see option errors but see what you get then is a good starting po

I doubt that it is a PS issue as unless you turned the 10v pot. Go back thru all of your PS to main board connections and carefully review every thing that was possibly disturbed during removal and re

Another technique is to use ChipQuick, which is a very low melting point solder. Thanks I was unfamiliar with ChipQuik, Got some ordered from GoKimco. Sounds like this should help solve the issue. Cra

To ensure that ALL the solder on both sides of the main board is molten, I used a Weller 100/140 gun along with the de-solder tip. Maybe add some chipquick to lower the melting point. Stock up on PCB

Wondering if anyone would care to pass along tips for removal of the larger can capacitors in equipment such as the 400 series power supply section. There are large quantities of solder and seems to t
