Bonjour, we recieved a fine TEK 492 SA, circa 1980s..1990s, fine condition CAL in 2007. SN B055xxxx Will post photo album. Q: Do these have the notorius SMD lytics on some PCB that leak and

Thank Benjamin for answering.... There is a 1000mfd/75wdc cap in the circuit, so there is a filtering (regulation) on this power supply, as I look with a scope at the waveform of the 32 v unreg, it is

When you look at the diagram, you observe that there is a regulation by the addition of a 1000 mfd/75wdc cap..and if it is really 56 volts, the value of the cap should be much higher..

Hi John: Thank you for your kind offer. I have a great 555 scope, which I intend to keep working. I also have types CA, D, W, 1A7, and 1A5 plugins. Would your parts stash include those from scavenged

hers the scriptblock part i talk

Hi i am Charlyd on the evvblog i thought i jump in here i guess i missed this perticular part, because i am a member in groups.io here..and very interrested in exporting the eeprom content on the

Hi John, Thanks for offering to share. Do you have many 7000-series knobs and potentiometers? I'm also looking for a correct graticule, light filter and CRT bezel for my model 511 and model 422, which

Schematic shows 52V typical with 116V supply voltage, 56V is not excessive especially if your mains voltage is a bit above 120V. Ozan

Unregulated voltage is higher than what us really "says". For example, the +5V unreg on my scope is around +11V, which then gets regulated to +5V. According to my service manual this is normal For

Hi.. I have a 465m with HV section blowing the fuse... Found that the 32v unreg source voltage to be 56 volts !! ..A look at the diagram show the transfo, then a bridge and a 1000 mfd cap rated at 75

Hi... My name is Richard, I recently acquired a 465m scope in mint condition..The problem is that the fuse in the high voltage PS burn instantly when the power is applied..Check all diodes,

Love to have it but is it in NZ? How much do you want for it? PM: ccdman1 at outlook dot com thanks

Hi all: To add a bit to the surplus equipment discussion. My employer (large aerospace company) had a surplus store for decades, which had most everything from soup to nuts (almost literally). I

Question to Jean Paul re: x-y distortion measurements method you mentioned. I have an HP334 Distortion Analyzer, and in the HP manual, it tantalizingly mentions a way to view distortion products. BUT

CLARK! YOU WONDERFUL HUMAN! YES, IT's the same power supply module. Thanks a million! And a million over! Alex

Hi, After long hours of measurements, cleaning etc. I had a final look at the acquisition board again and identified a suspiciuos via close to one of the infamous SMD caps ( see pic ). I traced it

Hi Simon, Thanks for the response. After long hours of measurements, cleaning etc. I had a final look at the acquisition board again and identified a suspiciuos via close to one of the infamous SMD

Hello, some time ago I have acquired TDS744A in unknown condition. Whet it arrived it didn't turn on. I have checked main fuse and it was blown. I have dismantled the scope and found that power
