    Default Velleman 8020 Pre Amp ( updated )

    Velleman 8020 Pre Amp that's been updated with the info gained on this page ...

    http://www.hardwareanalysis.com/content/article/1826/

    See the Schematic links for the changes made.

    I believe this disconnects the +6db gain option but it doesn't need it anyway as it has plenty.

    I bought it after I sold my Promitheus TVC passive pre and it made an immediate difference for the better, more dynamic, more impact but still has clarity and detail too.

    For the money it's a great little pre amp, and you can try different valves of course, I have Seimens Mica 3's in it at the moment, but it will be supplied with the Valvo valves that it came to me with. ( I'm keeping the Siemens )

    A few little marks on it but nothing too noticeable in use, there is a little mark on the top edge of the fascia but only seen if you look closely.


    245 including postage within the UK.

    Still for sale, happy to swap or part ex for similar size pre.

    DAC/Pre considered too but must have a great Pre side, the DAC/Pres engineer tried so far haven't been great on Pre output.

    Nice pre Mike I had thought about this when one came up previously about a year ago in a rather tragic sale (is this the same one?).

    Can I ask where in the article the reviewer lists the upgrades so they can be replicated? Did you do them yourself?
    Thanks, Lawrence

    If you look on page 2 of the link I posted called powering it up, you'll see a schematic link that shows the changes made to improve the amp.

    Firebottle did the work for me.

    I think it's the same one as you mentioned.

    Cheers

    Mike.
