I do something similar. Not sure I get the role of the resistors. Can you post pictures ?

Have a look at post 10206 of the F5 Power Amplifier thread. F5 power amplifier. The resistors are inside of shrink tube.

Cviller: I just orders some PSU boards and forgot the Rectifier boards. Do you mind canceling my order so that I can re-do it with the Rectifiers? That way I won't get smacked with shipping twice.

If it's not possible or you don't get this in time, no big deal.

You can ignore my last post. It will be easier for both of us if pick up some rectifier blocks instead!

Sorry for the confusion.

Hi ,
I am in a bit of a mess with the F5 project. I purchased my boards back in September 2009. I have only just got around to (starting) to build them... too many other projects.
Firstly I have found that the resistors provided do not match what is on the F5 BOM (from TechDIY). I was about to ask for replacements when I found that I do not have a current schematic showing what resistor values are actually wanted (this is a V1.0a 2009-03-14 board.)
Can anyone point me to a schematic for the V1.0a which defines which resistors should have been provided?
Thanks for the help

Default Cross-Post.. cross-confusion

thanks for the fast response / ticking off.

There is a reason for the cross posting.. I was hoping to pick up on all the changes as discussed in the various forums, not just those specific to your boards.
The boards, as delivered, have missing resistors, as well as wrong value resistors and resistors which physically do not fit on the board. Before resoldering and/or reorderingI need to be pretty sure of what should be there.. hence the cross posting.
After a certain point the size and scope of forums become very hard to manage when seeking a definitive definition of components. It would useful to have a "sticky" area in your blog to make this definition... as it is we are all reduced to searches which often return references to missing or outdated documents. In the professional world we would put all this under the heading of Configuration Management .... tedious but essential

best regards

Default Which trim pots?

There's lots of different mounting styles for trim pots, which one fits the P-F5-2V20 boards properly?
