Heathkit IM-105 Schematic & Cal Info Needed

Isn't that something else, when you can find it all over the place, but for some reason they want money? I just can't fathom why that would be?

I have it but I paid for it. It's easy to pay for...

You can buy a complete repro copy from

It's the difference between helping your neighbor fix his plumbing...or... demanding that he pay you to hold the pipe for him.

Don't know about you, but I help my neighbor FOR FREE when he asks... I often volunteer if he doesn't ask.

Think about it next time you ask for help.

Sadly, I don't have the schematic asked for.

It's a Heathkit IM-105, why would he spend money to get a schematic to repair it. Some helpful guy will make a copy of relevant pages and get him on his way. Mikek

This might help explain (or help confuse) whatever is happening with the Heathkit manual copyrights: As always, just follow the money.

I just realized I have one of those in a pile here somewhere, which means that I have the manual. Digging... yep, got it. However, I'm lazy. Just download the JPG schematic and bug me if you want something scanned or photographed out of the manual.

Incidentally, the taut band meter movement is almost indestructable, making this meter well worth fixing.

Helping your neighbour sure.

The manuals cost 30 to 40 bucks and they are old and most are falling apart. He's asking alot for a stranger. A neighbour yes, one or 2 sheets to copy yes, but it alot to ask on the internet for more than that.

I hope somebody is able to help him and has the time to.

try IM 104 on

Ugh. Pet Peeve.

Pick a compressed bit map file type like monochrome .pdf, or monochrome .tiff, or .gif, or .png for line drawings like schematics. Both .tiff and older monochrome .pdf files can use the fax (CCITT Level 4? or something like that) compression scheme which gives pretty small file.

.Jpg with it's "some sort of Fourier coefficent" compression sucks for line drawings. Artifact city. (Color and grey level .pdf and .tiff sometimes use .jpg. Both .tiff and .pdf are really just wrappers around a collection of compression schemes).

Hi Jeff,

Some very nice person gave me almost everything that I was looking for which was really nice but I only need one more thing. Jeff do you have the parts layout drawing showing where the resistors and adjustments are located? Appreciate your help.

Never mind the email. I'm going to be busy tonite. Here are the files in PDF and JPG:

I have a manual for the IM-105 and would be happy to send you the schematic and calibration instructions if you still need them.
