Hi, Would strongly suggest you install a 350v AC rated X rated capacitor rather than a 300v component, particularly if being used in a 220/240v AC environment. 350v components are readily

HI Milan, The CLIP is very useful.? It is nice that it includes all of the options too.? Thank you for making that available at a reasonable price. ?I guess the inductors were a bit lighter than

C8 and C9 are 0.47uF paper coupling capacitors which can leak current, which will change the output tubes bias and cause them to conduct excessive current. Those mica will fail shorted, or simply

Mica caps short from silver migration. I used to see a lot of them going bad in IF transformers when the gap got small enough to arc. The radio sounded like heavy thunder. One TV transmitter that I

That is true, and not for sale. Bill Lauchlan Sent: Wednesday, November 03, 2021 4:00 PM To: [email protected] Subject: Re: [HP-Agilent-Keysight-equipment] HP ET8866 True

Leakage in C12 is unlikely to be a serious problem as it's a high value electrolytic in a low impedance part of the circuit and not in a position where leakage would make a difference to tube

I'm currently working on an 8594E power supply, and replaced the RIFAs. C103 C104 and C105 are 0.1uF x2 250V I replaced them with these: Mouser #:

Hi Dave, Thanks for the info! I?ll let you know what outcome will be Best regards, Mark

Yes Mark, that should be close enough. Just be doubly sure that you're matching or exceeding the safety class, and staying within the same type (X vs Y). Good luck. Man I do NOT like that

PLCC only acceptable and only in Industrial or Extended temperature range. -JW is LONG gone Sent: 03 November 2021 17:17 To: [email protected] Subject: Re:

Hi Dave, Thanks for yor quick response. Yes my whole house was smelling for some days. SO if I take e.g. 0,1 uF that will do? Best regards, Mark

Ahh, a Rifa. Bet that smelled nice. The capacitance of these line bypass capacitors is not at all critical. Just find one of the proper safety class and the right physical parameters, and it

Hi Roumen, I have an HP8590 with the 0950-1977 power supply unit inside. In the power supply the Class X capacitor has melted down. I want to replace it, but I can?t read the Farad value

HP used "ET-xxxx" for Electrical Tools, and "MT-xxxx" for mechanical tools. These were usually one-off things or built in very small numbers, but they were often designed and built with the same level

And…documentation will be almost impossible to find and may have never existed except in the tech’s personal notes. wrote:

ET stands for Engineering Test. ETs were commonly built for in-house use at HP manufacturing facilities and rarely if ever sold directly to customers. Certainly possible a “good customer” might

I did not catch the earlier thread on the 437 meter. I will bet thats exactly the same thing going on with my meter. Its a small cheap meter. Not very HP at all. Thanks for the

Inductor was ignored coz i scanned CLIP with wrong settings... Milan

ET numbers usually meant custom in house test equipment of fixtures (and likely one of a kind, or very small custom run). Daun

Jim, Pictures would help. Any part numbers on the main board or display? 73, Steve WB?DBS
