Hi Everyone, I'm definitely a newb to electronics repair, so I wanted to get some advice about my Tektronix 2467b. On startup, the scope errors out with one of two codes: "Test 05 Fail 04" or "Test 05

I have to replace the large power transistor on the A6 inter board the TIP35A one it was damaged from prior ill handling plus it appears to have been overheated at sometime as the case is deformed. I

Hello Guys, Many thanks for technicals comments, thats great ! I must keep your advice in a corner of my brain when I work on any stuff with digital signal. Regards Alain

Fifty feet ? Nothing, I got batteries ! LOL But if I ever need a cord I have no idea where to get one and I don't even have the DC cord. I reluctantly recommend a modification - to myself. Hell, it's

Hi all, Just found out about this group and I hope you all can help me out a little. I bought a 2215 off ebay (and subsequently got my $40 back no questions asked, so not only did he know it was

Whoa, why did that cap blow in the first place? I used my 7A22 and I remember that I was careful to keep the overdrive lamp off. I used the filters to remove LF and HF as much as I could so I like to

"It seems to be working with a good sine wave on both channels from the calibrator" ??? Is this the calibrator on the scope? If so, it should be a nice square wave. Are you using a scope probe?

Triggers are derived from the appropriate channel, or externally. They're processed, and that signal is used to trigger the sweep. AUTO triggers the sweep at a fixed rate in the absence of a trigger.

Hi Leo, For some reason the photos you think you are adding to your photo album today, are not showing up in the photo album! tom jobe...

Hello John, As a general rule of thumb, a thorough check of the Low Voltage power supplies, both for voltage on spec and ripple are both important and yet, an easy check. Not just because problems at

Hi Tom, Thanks for the documents, I added them to my 2215A paperwork and checked my scope for these mod's. I am in Spain, but based on the SN (204xxx) my 2215A was manufactured in the UK, so it's

Greetings All, I recently purchased a 465 on Ebay UK, having now cleaned it up it's looking good, It seems to be working with a good sine wave on both channels from the calibrator, but the only way I

Hello Kerry, Just a correction... While the hypothesis of the ÷5 stage misbehaving is still sound and would cause exactly the symptoms you describe, I got wrong (and stated wrongly) that the slower

Hi Leo, I didn't see the photo(s) of your Schaffner AC inlet filter posted, so I put two photos in your photo album of some of the Schaffner filters I have that were taken out of some 22xx scopes.

Hello Kerry, I don't own a TG501 so I don't really qualify as an expert, but I downloaded the service manual from the Tekwiki (here: http://w140.com/smb/TG501_SM.pdf) and, by just looking at the block

Hi Tom and others, Sorry for my mistake of changing the subject, I have messed-up, so there are two threads now, I promise to not do that again... :-( Anyway, I added a picture of the two RIFA

Hi Miguel, That is definitely an odd number for an option. Up until now I would have said options are ALWAYS listed in the catalogs as opposed to modifications which are never listed. But I just

Hello I'm a newcomer to this group who has fairly recently acquired a SG503, PG506 and TG501 in a TM5003 module. All of these units are working fine, apart from the TG501 which shows some odd outputs
