    El Cheapo Bass-O-Matic amp build

    I want to build a cheap, no frills, power amplifier.

    The plan is to use it with an active pickup bass, hopefully without a preamp.

    Class D SS, 600 Watts into two ohms.

    All new parts with a total cost under $250.

    12X12X3 aluminum enclosure.

    Sure TAS-5630 1X600.

    Mean Well 12.5 amp 48volt dc power supply.

    Various bits and pieces.

    I just ordered the parts tonight.

    I’ll attach some generic photos of parts.


    Thanks to Mark Fowler for the idea.

    It is wired and alive and has a nice clear sound.

    I learned and relearned couple of things while building it.

    Mask your plates before drawing on them. I don't know why I didn't do it this time. It Is A PITA To Get Sharpie Off Of Aluminum!

    6 volt bulbs don't last long at 120 volts. Yeah, yeah, yeah. I know, check first.

    Thank You, Gentlemen.

    It was fun, something different.

    I did manage to find some time on Friday evening to run it as the power amp in my main hifi.

    CD direct input into Klipsch LaScalas.

    Tull, Little Feat, Genesis, Metallica all sounded nice at mid volume.

    I do have some sort of loading problem on the volume control, the sound really opens up in the last 7/8 or so of the volume control. I used a 25k pot, maybe I should try a 100K?

    heh heh, I saw the Tubes at a place in Manchester. After the show was over, I saw a girl from across the room who had the most awesome headlights I've ever seen in person. They were jaw-dropping beautiful I literally stopped talking to a friend and stared in dazed astonishment. My friend turned around to see what struck me and hollered "Hey honey my friend here likes your tits."

    She was not amused
