Message	Date	From	Subject
Hello to all in the group. I have purchased some Far Circuit Zero- Beat circuit boards and the parts list that came with them calls out Mouser part numbers that are not used any longer. I emailed Mouser to see if they could convert their old numbers to their new numbering system but no luck. Here is the website of the parts list/pcb http://www.n0ss.net/kr5l_led_cw_tuning_ind.pdf Could some one, who understands board design/layout , update the parts list so I could order them and build these boards up?? I am looking for the proper tolerances/composition and size to be able to use the pcbs from Far circuits. This would be a great help to me. I am not fussy the parts supplier does not have to be Mouser, it can be whoever you are comfortable with and will handle small orders. Merry Christmas and Happy New Year to all. Brad N1VWD

Brad: None of the tolerances are critical. The circuit uses a multi-turn pot to adjust the frequency. The resisters can be metal film or carbon film, 1/4 or 1/8th watt, 1% or 5%(in many cases, 1% are actually cheaper and more readily available). The only critical cap is the .47(use the type specified). The search feature on Mouser will reveal many candidates. You will need to look at the board to see if the capacitors fit the mounting spots on the board. Dave - WB6DHW <http://wb6dhw.com>

This is somthing you should be able to do your self, Ordering components are an important part of all projects. I'l cut you an deal: You find the resistors needed, they can be 1/8W or larger, 5% or less. The rest is: Mouser no. for the components, first choise found: NE567 526-NTE832 5K pot 72-T93XB-5K (this should fit board) 0.1�F 81-RDED72W104K3M1C1A 0,47�F 647-QYX1H474KTP 10�F 667-EEA-GA1E100B 22�F 667-EEA-GA1E220H 100�F 661-EKZE250ELL101MF1 There are for almost all components more than 100 alternatives that can be used. That said, It's kind of hard to figure exact sizes from an coarse board layout, so you may want to check the leg spacings on the capacitors. Also, I'm not so familiar with the US shops, so I may not have selected the cheapest components, but none of them are realy expencive. 73 de Thomas LA3PNA/AE5YS. 2011/12/22 Bradford <n1vwd@arrl.net> > ** > > > Hello to all in the group. > I have purchased some Far Circuit Zero- Beat circuit boards and the parts > list that came with them calls out Mouser part numbers that are not used > any longer.

Brad, There's only one tough part on there (tone decoder) and Mouser has a cross reference for it. I would suggest you dig into this and try their web site and word searching to identify the parts you need. You can do it and it will be a big confidence boost when you succeed. This sort of Mouser order will be very little cost wise so even if you goof it won't hurt much. Just search with the actual part description in your build notes and you'll find everything. If you just can't figure a part out come back here and ask. John KC9OJV ________________________________
