D*A*M: Red Rooster Booster, Tag Board Layout

While I was thinking of what could be made with tag board off-cuts, this popped into my head. 

The D*A*M Red Rooster Booster is probably my all-time favourite booster - I've only ever made one, and it was so good I stopped there (it was a point-to-point npn version with trimmer).

This is a PNP version; the 3k9 resistor could be swapped for an upright/inline trimmer.

Fun fact: In Australia Red Rooster is the name of a cheap roast chicken franchise.

  2. Hey Thank you much for posting this, I am building this on a Tagboard myself...

    I have a few queries though, apologies for sounding lame...just wanted to be sure..

    1) Does the Emitter connect to Lugs 3 of both the pots?
    2) Do the centre lugs of both pots connect to each other and then to the Collector of the Transistor?
    3) The blue wire, connecting the Negative of the 47uF capacitor, connects to the Emitter + Base + Negative terminal of the 1uF Capacitor & the 4.7nF capacitor as well?

    Appreciate your inputs please.

    1. You can find a schematic here. https://www.pedalpcb.com/docs/Chickenhead.pdf

      Only difference is the layout above doesn’t have a trimmer on the emitter.

  3. Hello. Probably best to put this next to a schematic to get your head around connections, as you appear to be having a lot of trouble making sense of this. And if you have any issues at all, trying to fix it will be very hard.

    1). No they are not connected. Boost 3 to V- Range 3 to Range 3.

    2). No they do not.

    3). No they do not. 1u and 4n7 connect to the base. The 47u connects to the emitter - the base and emitter are not connected.

    1. Thanks much for the inputs Andy, I got confused due to the colours matching on the pot lugs with the Transistor lugs (it is done usually on larger schematics/layouts where instead of wired connections, reference points are made. But thanks for clarifying....I was working without a schematic, now that you have shared one, I get it.

    2. Fair point about the colours. I might update the layout to make it clearer. Hope your build goes well.
