    Hi I thought someone might be interested in this little project.
    I needed a little practice amp so I can play in the conservatory & not bother anyone at night & my 300W Ashdown was a little bit too loud & big so I built my own using old scrap parts.
    I took;
    a 40W amp circuit from an old ministry of sound sub I found in a skip
    a 12'' 250W PA Skytech speaker which I had in the garage
    & an old wooden cabinet.......
    & swapped the line input for a quarter inch jack from an old broken radio.

    It works well! There's no volume control or tone control on the amp so it's all from the bass & the on/off & input jack are all on the back. Anybody can do this with a little bit of soldering kit & some basic electronic knowledge.

    This is what I have learnt;
    Big speaker cone gives nice bass
    Wood selection & panel placement makes a HUGE difference to the amps tone

    I even upholstered the front panel with an old t shirt! Let me know if you need any help on building one of these. I built this in 1 evening using a jigsaw, staple gun, soldering iron & a screwdriver. Seriously for £0 It's worked out better than I could have imagined!
