    Hi !

    This is my first build, a 5F1 circuit (with a switchable power mod, an output to use it as a head and a tone pot.) It comes from a ampmaker kit (UK).

    I put this baby behind a metrix generator front (an old french brand for electronic devices), reused the knobs and switches, and cramed a 8" weber in a homemade oak cabinet. Nothing fancy, but sturdy, kind of steampunk and practical !

    It sounds like it should be, really. The speaker is kind of big sounding !

    I still have to look for some rattling and fine tune it but I'm really happy with it !

    At the beginning, it was an am-fm generator looking like that :

    Repurpose builds can provide a cool look. They can also be an opportunity to link someone’s history to their music. I have a friend that is an retired environmental engineer and a guitar player. He is looking for a piece of obsolete test equipment he would have used in the early days of his career. We will convert it into an amp. Something that has memories but no current use. It can tie together parts of life that are meaningful to the player.

    That's well written. Things want to live second lives rather than getting dusty and forgotten.

    That's how I have an old coffee grinder as a lamp, a generator for an amp and an ex-colleague as a wife.

    I'll have to take a look inside one of the HP signal generators. I wonder it the power transformer is big enough to supply a JTM45. :sneaky: It looks like the one on FB has a pair of 5881s, so the answer should be yes.

    The HP 200CD signal generator already has a pair of 6CW5/EL86 tubes in it! That's half a guitar amp already working. :cool:
