    The LoFi is still here, the switch to turn the effect on and off is a bit dodgy, sometimes it works sometimes it doesn't. Probably fixable if you can get a hold of the right switch. If you're in the US there's not gonna be much point shipping it over there, it'll be way cheaper to get stuff over there due to the exchange rate, VAT and the like.

    £60 for the Whammy, £600 for the 6505

    Right, got some more pics I've just taken, showing the mods and internal wiring of the mods in case some people have been put off by the self-modded thing.

    Wiring for the bias pot. The white stuff is glue, and there is a resistor there so if the pot goes bad the amp will keep working, on stock bias voltage.

    As you can see, the choke is bolted to the chassis, it's definitely not going anywhere.

    [​IMG]
    Wiring for the choke, it replaced a large black power resistor. You can see in the middle that a flyback diode has been fitted: this stops speaker pop due to the choke when turning the amp off.

    As you can see, none of the mods have been simply slapped on, they have been thought through and fitted to take a beating. Even the front grille has been thought through - the emblems have been screwed to pieces of black wood through the grille, which makes them seem to float. The grille itself was stapled to the amp's plywood shell.

    £600 firm.

    When the flyback diode, is a normal (1N4007) diode, it's connected the wrong way, and shorting the choke!

    You sure? The amp's been to a tech who fixed an unrelated problem, said the mods were professional looking for DIY, would've thought they'd be the first thing he checked.

    And jamesrt2004, this is off the market for a little bit, think there's a problem with the tubes because it was making noises a while back, sorry about that!

    Yes I'm sure! The amp will function though, and the diode will prevent the amp from popping when switching it on standby, but the choke is out of the circuit, and in the end the power tubes will fail, because there is to little resistance in the circuit. The choke has a resistance of 250 Ohms, and now it's zero Ohms, because the diode will short circuit it.

    Hmm, well the amp was running for about a year after the choke was installed, went to a tech to sort a problem with the preamp board and worked fine afterwards. Not used it much in the past year. May have to remove the diode and rewire the standby switch as written here: Mercury Magnetics - Premier Magazine article

    Thanks for the heads up! We should probably stop chatting in the FS section though, PM me if you want to talk a bit more about it.

    THE 6505 IS OFF THE MARKET FOR THE TIME BEING. Whammy pedal is still here.
