They're WIRES. WIRES can be removed, put in a big bin, and sold to copper salvage companies.  Scopes?  They'll sell for just as much without the power cables.  Probes (attached or otherwise) Gee,

interleaved: What I'd like to see is a way that you can get to the connectors gracefully, a breadboard connector is one of those ways. No idea how much they cost, they may be rare.  If you had

I’m not particularly focusing on that. But since he mentioned it apparently in response to my mentioning that the voltages on pin 1 were a tad higher than what the schematic calls for, I though it

I don't think you should focus on that, the specifications of TM50x are very loose. The +33.5VDC is specified to have a tolerance of +23.7V (low line full load, worst case) to +40 VDC (high line, no

I have a Hakko 470, can it use that diaphragm ? Best, Bill

ISTR that when I recapped my TM-501 the voltage selector jumper pins were labeled with the various line voltage ranges such that if I knew the line voltage in my lab I could set the jumper correctly

Hi everyone, I recently purchased a 11801B with an SD-26 module. Because I haven't used one before, I'm trying to understand if the behavior I'm seeing is expected or if the equipment is

I have a similar issue and I think your post is sort of answering the post that I just made. You can take a look at the comparison between the edges I get when the delay is very short to when the

Yes, I agree. But the thing is, as I said earlier, I see where the jumpers are, but I don’t see any indications anywhere as to how to change that. On the power cord retainer outside there is a

Hi Stephen, Yes, maybe you're wrong. Hardware is not software, you cannot always crash, fix, restart, and continue. With software, with the advent of Internet and ubiquous connectivity, you can

Stephen, Be sure the input voltage selector jumper inside the TM506 is set to the proper voltage range your electric utility provides. If they do not match your power line voltage the three AC

If you look at the back of a horizontal 475, lying on a table top... (not standing on its feet)... it looks, by your pics... that the intact foot in those picture... is one of the two feet, on a

You’re absolutely right. I’ll see what I have in my stash. Thanks for pointing that out.

I am interested in the scope and plug-ins. I have been looking for one of these for a while, and have a definate use for it. I am in Syracuse, New York, so picking it up is not possible. I have an

How about using 0.33 ohms in parallel with 1.5 ohms, for 0.27049 ohms? Certainly closer than the resistor tolerances. Steve Hendrix

Yes, you’re right. There is no load at the moment. Any other pins/voltages I should check before calling it good?

I’ll see what I can find, and if it’s not costing an arm and a leg. How do I know that? The ones I have so far are: 1- PS503A (which was working fine until the 7.5A fuse blew) 2- SC502 15Mhz

This one *IS* mine! It comes with 6 plugins, and works. 2A63 2B67 3B3 3A3 3A74 3A74 They can be shipped, but after ?Aug 10th? and probably $85 shipping. I'd like $30 for all that picked up

Yes! Around here, they do toss good usable Tek equipment into the dumpster... but, they always keep the power cord. I'm not sure of the thinking (One could need a 1 dollar power cord; but, not an
