This post has virtually all the values.
I got some stuff from the local surplus store. You can use through hole resistors easily on the pads. Everything bog standard really.
You need the adjustable version of the mic https://nl.mouser.com/ProductDetail/998-MIC5156YN
If you are using the "through" hole version get this pot: https://secure.reichelt.nl/nl/nl/pr...den-staand-10-k-ohm-64y-10k-p2716.html?&nbc=1. The smd board cleverly allows "all types"

So sorry no bom.

Swopping polarity will work as well. Swopped the polarity around on the boards I bought from you. And then there is 8 volt accross them with negative probe on negative pole and positive probe on positive pole.I replaced them with unpolarized caps a while ago. Measure the bridge and get some unpolarized replacements 47uF 25V
So the IRF840 is doing fine in this circuit? I have also purchased them for this board.I found the fault.
I found out that the experiment cables that I use between the trafo and the 6,3v module are to thin that I get a voltage drop.
I took another pair and paralleled and I now get 6,3v dc out.
The rectifier is SB560.
Will change to unpolarized.But it still working as it is.I think they are a part of a voltage doubler.c1 and c2 are the wrong way around still. Check my post 87 and 88.
