I was very pleased with the manual I got for my amateur (ham) radio. Without it I could not figure out how to input and/or change the P/L setting on my radio. It drove me nuts as the radio was essentially useless. That all changed when my manual came. Then it took only minutes and I was done. Now my radio works fine. This is an exceptionally good resource as it's a very easy and user friendly download. Thank you very much! Dziękujemy za!
Last week I bought a second hand BAUKNECHT TRK4850 DRYER. It is a professional machine with many programs and switch options. I feared it would be a huge quest to find a manual. I was delighted when I found owner-manuals.com. After payment I received the file to download the next day already. The quality is great. I am very happy. Thanks!
but kindly the distributions of the operating programs not find in the owners manual,can you help me to understand the operating programs instructions thank you

Section V Paragraphs 5-74 to 5-76 5-74. The cause of excessive output ripple on any of the supplies can be isolated in the following manner. Measure the ripple at the output of the rectifiers of the supply in question. Compare the measurement with the value given on the schematic diagram, figu r e 5-33. If the ripple is excessive, check the input filter capacitors and bleeder resistors. If the input ripple is normal, the cause is most likelylow gain in the amplifier transistors.
Model 175A 5-75. Table 5-5 gives troubleshooting aids for locating causes of loss of regulation in each supply. 5-76. The balance between the +6.3 volt and -6.3volt supply outputs and ground is determined by the supply load. The load is a series-parallel arrangement of tube heaters, diagrammed in figure 5-34. An unbalanced output voltage can usually be traced to an open o r shorted tube heater o r a wrong type tube.
