Hi. I'm looking for a bit of guidance here please. Since moving house a couple of years ago I am only just getting some test gear set up. I find I have 4 good genuine Tek probes to go with the 4 Tek

Hi all, What is curious is that I tested the FET on my curve tracer, and it looked OK - both FETs display near identical curves (Id over Uds as well as Id over Ugs) and the curves do look normal and

I'm 99% sure it's a 453 tube in there, and it was probably like that when his Dad bought it back in 89. It in part might explain his defensive responses (that's the polite way of describing his

Sean: from the symptoms, a possible scenario is that the EHT regulation has failed. I always dread going into that box! I'd suggest you open up the back and find / remove F1437. You can then power the

I asked about that. I wrote: "The CRT has clearly been replaced with a smaller than original replacement. Do you know what the replacement CRT is from? Have there been any other replacements and/or

On my unit I have the binding posts as follows: Hi: Red Lo: Black -15V: Green Gnd: White +15V: Red +5V: Red Which is how the photos on the Tek wiki of the Tek made units have it. (I also have the Hi

It just doesn't look right, that crt appears to be slotted into the space where another crt once lived. Maybe his late dad replaced the original crt when it failed? Geoff.

There's a guy listing a 453A scope which appears to be equipped with the CRT from a 453 (6 div vertical, not 8). The current ad is a relistng as it didn't sell last week. I contacted him before the

Just now I got thinking more about this. The TD is in parallel with about 100R load (47R resistor to 50R input 3S2). That's a heavy load for Ip = 1 mA! The TD wants to switch to its high state at

That’s disappointing. There is another layer of the onion yet to peel, apparently. The better data sheets show you the test circuit, while others just give you the test currents and leave the rest

Accordians use bees wax mixed with pulverized crushed rosin to increase the melting temp and strength to hold the reed blocks in.? Would this mixture help?

jrseattle, I wonder if C776 is leaky. That will cause problems if it is leaky. This is a part that can load down the circuit. Those I always replace with a film type. You said a problem could be to

I received another patient...this time it's a 454 that is outwardly fine (actually it's in superb condition), but had a very serious HV fault. Apparently the previous user was using it and it started

As I recall, it is secreted on trees, scraped off and cleaned somehow. Over the past thirty years or so there have been numerous articles about the origin of shellac in Fine Woodworking magazine. That

Is it secreted? I always thought it was distilled from the bug's shell. -Dave

Probably came from a hamfest, the yellowsheet, gift from friend, etc. Stuff I sold on eBay made it to Hawaii, Japan and Europe.... Also lots of stuff from St Louis migrated eastward. then there is

That or Y-12, but I don't recall if Hughes was ever involved with Y-12. Sean

Hi, Tom. I received the UF4004 Ultra fast diodes and replaced the 1N4004 diodes in the circuits loading the secondary of transformer T710 but to no avail. The behavior hasn't changed. Just curious
