    Building my first amp is what motivated me to really learn electronics. If you study and build you can really take a quantum leap in understanding how and why electronics function.

    Youre very welcome ;)

    Btw, when I decided to start learning I barely knew how to turn on the TV... (No kidding) Lol

    I'd have to agree with that one...

    I'm quite impressed about how much faster i'm learning as I build. It's like everything makes sense now. Nothing like "real life" experiences.

    This is encouraging and it's good to know to start with the books first instead of just diving in and hoping the kit instructions are good enough, which I'm thinking they wouldn't be by themselves.

    first kit I bought (Chinese 5E3 kit from Mableaudio) came with no instructions what so ever and on inquiry I was directed to google.
    It came out quite well but there was quite a bit of debugging to be done. luckily my father (who has forgotten more than I will ever know) is an electrical engineer.
    he helped with the first one but made me learn how it all worked.(give a man a fish......) now with the help of this and other sites like it I can usually fix all my feckups myself.

    and there is no such thing as bad knowledge.

    Ok, how'bout this mess here? ;) ...will those straight parallel lines cause any hiss?

    Thank you.

    Looks good. My only concern would be ever trying to get one of those pots out in the future.... not much wiggle room on the wire.

    Copy that.... it was real tricky installing all those wires with so little room, hope the pots will last a lifetime, they're supposed to be the best there are (apart from NOS military pots of course) they're PEC. But since I'm the one who will be servicing this amp I don't think it's going to be much of a concern, I hope... ;)

    I used PEC on mine. Should be fine. *knock on wood*

    Almost there! Gotta solder in the OT, the grid stoppers on the power tube sockets, the resistors for the NFB, the power cord and it's done :)

    Please help me out a bit and see if you catch some mistakes.

    How's the wire dressing?

    Looking really good.

    Remember not to shorten the wires from the output transformer until you verify the NFB is working properly. If you get the loud squeal when NFB is engaged you'll need to swap the OT wires at the power tubes.

    Any downside to keeping them long and pulling them tight through the back of the chassis?

    Not really unless you're OCD and then it'll keep you up at night.

    Nice work.

    What is an NFB switch, and what does it do?

    ok, @robrob (or any other) maybe you can help me out a little here... I understand that you recommend to connect the negative feedback resistor to the 8ohm pin on the impedance switch (when using a multi tapped OT) so that if I switch to lets say 16 ohm it will have the correct resistance coming from the NFB... is that right? If so can you explain how does it work? Because I tend to think that each pin in the impedance switch should have the correct resistor coming from the NFB selector switch. Because if I switch from 8ohm to say 16 ohm impedance the resistor along with the pin connected with the 8ohm tap gets disconnected from the black wire or center pin.

    I'll appreciate if any of you guys can throw in some light.

    thank you.

    Guy.
