My 214 and 222 do not. No. The 214 is an analog storage ’scope, so quite different. The 222 is a different size.

I had the same problem with my 7623 (not an 'A' model) and it turned out to be one of the transistors on the horizontal output board was slightly loose in its socket. When it warmed up, the transistor

Looks to me like the same as the TekWiki photo, differing only in a broken Cursor / Sweeps knob and yours has a darker CRT filter.

Mine doesn’t.

Like a Tektronix 109 pulse generator. See https://w140.com/tekwiki/wiki/109

I've got the BNC version of this: http://www.leobodnar.com/shop/index.php?main_page=index&cPath=124 I'd bet a lot of us have at least one of them.

You’ve tried https://w140.com/tekwiki/wiki/TDS754 ? I only briefly glanced, so don’t know if there are schematics or not…

I have a 214. I installed NiMH packs to replace the failed original NiCd packs. It works well. See https://w140.com/tekwiki/wiki/214 for schematics. I’m afraid I don’t recognise the component from you

Python long pre-dates Arduinos (certain boards can use a special version of Python called MicroPython) and Raspberry Pis. It was first released in 1991, but over the last decade has seen a surge in po

As an electronics hobbyist, I collect and use vintage test equipment, especially Tek ’scopes. Indeed, my Tek 2430, 2465B, TDS350 and even my 466, 564, 549, and (very handy!) 222 portable are both part

Would anyone still be using a 1980s era 'scope for professional applications? As a professional software engineer, that sounds to me rather like someone using an 80's era PC for commercial software de

There seems to be some variability in normal operation, so best to refer to the setup instructions in the service manual for intended behaviour. That said, my 7623 behaves rather like you describe wit

Fan speed is temperature controlled, but on startup it should spin -- though slowly enough to be quiet.

Yes, I am. That 2430 is now in great shape and in regular use on my workbench.

I was tempted to bid on it to get the DM44 and transplant it into my 475 or my 466, but I decided I’ve got plenty of better DMMs around, and don’t need more 4xx series ‘scopes. So seller cancelled the

I'm the proud owner of one Type 191 in as-new condition. I mainly use it for its intended purpose, measuring the bandwidth limits of (mainly) 'scopes & plugins up to 100mhz. It seems a shame to modify

Thanks, and good points — I’ll keep my eye out for better probes in original condition.

I'm not sure it's worth returning, particularly as it's my fault for buying the cheapest P6137 on eBay at the time. 😊 I have another P6137 that cost several times what I paid for this one, and it's fi

I just acquired a P6137 probe fairly cheaply, and I can see why - it's been assembled from other probe parts and the indicator switch on the cable assembly (174-1081-04) doesn't work: what I assume is

But eBay Japan seems fine, or at least it worked from the UK when I looked at the 2466BHD listing last night.
