A friend asked for my help troubleshooting an Eico 235 VTVM her Elmer gave her. Someone has been messing around inside it, so I don't know what is stock and what has been ... um ... improved. Although it uses the traditional (miniature era) 6AL5/12AU7 tube lineup, it does not seem to share the schematic of the other Heathkit/Eico VTVMs (at least, not after the changes it's been through). I'd love to help her get it going -- it's a nicely built meter and looks like it has real potential. But I do not relish trying to trace out the function and range switching without guidance. So, if anybody has a manual they could scan (or, failing that, a schematic), we'd be very grateful. If you have an original hard copy you would sell, even better -- she'll be happy to buy it. Finally, if you have a hard copy but aren't able to scan it and don't want to sell it, could we borrow it for a week or less to scan it here? Please help if you can. Thanks! Charles

An Eico 235 is the as a 232... differing metre style is the only difference. IIRC If you can't find a 232 manual send me an email offline. I send it when I'm not on my phone..

Some Eico manuals, including several for model 232 are at: http://bama.edebris.com/manuals/eico/ Joe Hobart Flagstaff On 7/31/2014 3:46 PM, David Holland wrote: > An Eico 235 is the as a 232... differing metre style is the only > difference.
