The normal small blue ones work fine - pins are fairly close and in line or in a v shape (there is an extra middle one). I can't remember the exact package code.

Hi,
the advantage of 3pins inline (sil), is that one can orient the VR to enable which direction you prefer to turn to make an adjutment.
The disadvantage of the 3pins inline, is that one can insert it the wrong way.

The advanatge of 3pins offset, is that one cannot insert it the wrong way.
The disadvantage is that the designer might have a different idea from the user on which is the preferred way to adjust.

I measured mine before I soldered them in the board to make sure they were zeroed out while all the way counterclockwise, It's been a year since I assembled the boards. I still haven't finished the amplifier though.

Hi CViller!
I got your boards F5C V2. Can I use them for the normal F5, 25Watt? And I heard that the ztx 550/450 that I have, has to be for Q5, the round part in front and for Q6, the round part to the back? Is that right? Thanks for the answer. Grtz Teake

Hi Cviller!
I put the boards together, the F5c version from you, and got to much voltage on the output, 0,1 volt, and the powertransistors are getting very stinky hot. For R1 and R2 I got 10 watt 10 ohm resistors. Is it possible that the wattage from those transistors is to high? And are there maybe connecting points that I( missed, because I am using this board only for F5 purpose, and not for the Turbo version. Thanks for the answer. I think I got Q5 an Q6 right now an also P1 and P2.
