    I'm Oliver.

    Default IC: DCB1 Turbo 1.2A Preamp.

    Hi all,

    Initial put up as an Interest check.

    I've been giving some thought to putting a BigBottle phonostage PCB inside the DCB1 listed here.

    All is OK in terms of space etc BUT I discovered that when I fitted the extension bars for the Khozmo and the Elna switch, I had to make the holes in the face plate a little bigger to fit the sleeve they require.

    I don't believe I can get a tight enough grip on the Khozmo now, as I need to take the bars out to fit the PCB.

    So, rather than piss about with it and possibly end up no further forward, I thought I'd see if anyone wants to buy this one and I'll make another one to accommodate the changes.

    Inside the Box:

    DCB1 PCB with Dale resistors and Audio Note Tantalums in the most important positions

    Obbligato Gold capacitors

    Spotfire wire.

    Elna selector switch

    Toroidy Transformer

    Upgraded MUR120s (I think that's the number lol)

    Silver solder on EVERYTHING

    Running at 1.2A, thus qualifies as the 'Turbo' version and probably as high as you can go with one PCB before it melts lol

    The DCB1 was given the final once over by Firebottle when it was finished.

    As far as preamps are concerned, this has seen off everything that has visited here or been put up against it. It really is a class act.

    The price is set only so its possible to build another to this exact same spec, as I found it to be superior to other specs Steve and I tried.

    As usual, offered at the price it cost to build.

    Colection only on this as I have no packaging or send a courier or packaging and I'll post it.

    £500 collected.

    I may negotiate a little but not much.

    All response by PM pls.

    This could be ideal for Mikeandvan if his Croft proves to be causing his issues.

    I think the case is what sells this over over dcb1 builds I've seen anyway. Shows its all a matter of taste.

    I agree - the external appearence is excellent, and the internal construction is neat and tidy. Good luck with the sale.
