Dear all,
Here first how to treat pictures with a free picture software program, IRFANVIEW. At least the instruction is worth while. Use big sized pictures with a big object in them.

FILE UPLOAD SUMMARY
Please click on the bold underlined Links for additional information.
[1] Pictures of a tube (valve) should display the tube (valve) only. Please cut your pictures accordingly.
[2] Pictures for the Forum should be of reasonable size before upload, not shrinked after upload. Another "how to" is here. You can add high-res pictures and schematics using the Attachement(s) button beside of Submit .
[3] Even if you have preset the table width to 600 pixels you have to check wether the size may have increased by adding some entries. Enabling multiple lines for a cell will help you.
[4] Pixels at 300 dpi. A circuit diagram must be (rotated if necessary) in portrait mode, top to the left, the dimensions are rule. PDF is not allowed. A must to read is the "how to" here.
[4.1] For modern schematics printed in colors you find an orientation here. A special instruction is not yet available. If in doubt consult the schematic administrator.
[5] "Makers" is synonym for manufacturers and brands.
The above data are collected from all the i I have found.
Please click on [ Mail to the author ] in case of any complaint or suggestion.
Kind Regards
Georg
