    Default FS Art Audio Jota Silver Signature 300B SET

    This is Tom's top spec version of this amp with the following differences

    It has three inputs and a remote control volume so it can be used as a integrated which is how I used it

    It has been upgraded internally with all silver wiring and WBT speaker posts at the rear, - This makes it the silver signature version and I have the certificate for this.

    The power switch has been moved from the rear to the RHS so you dont have to reach over it to power it on and off

    The main caps have been upgraded from Musicaps ( Which a lot of people upgrade to ) to Jupiter caps

    It is fitted with Emission Lab 300b XLS valves which are very well made and last forever - Oh and sound great too

    It also has some high quality Reflektor 6922 tubes fitted

    When you look at it the rectifier tubes are not fitted as it does not need them - there are two silver caps fitted in their place - I have the tubes though,

    It was originally manufactured in 2011 and upgraded to silver spec in 2014

    It has the Sentry start up circuit which checks the circuits before powering them up.

    I would like £4,500 ono[IMG]IMG_2216 by S ONEILL, on Flickr[/IMG][IMG]IMG_2220 by S ONEILL, on Flickr[/IMG][IMG]IMG_2223 by S ONEILL, on Flickr[/IMG][IMG]IMG_2222 by S ONEILL, on Flickr[/IMG][IMG]IMG_2219 by S ONEILL, on Flickr[/IMG]

    Bump for this weekend - and still open to reasonable offers

    If by any chance anyone is waiting for me to drop the price by a chunk before pouncing you will be waiting some time - I know how good it is and therefore what it is worth

    I'm not sure I'm gifted enough to understand this. If it was originally built with rectifier tubes how do you take them out without consequences.

    I was speaking to a guy the other day who had the valve rectification changed to SS in his Cary amp, he reckoned it was better though he mentioned reliability rather than SQ.

    Reply from Tom below - Just goes to show the value of a good manufacturer too

    The rectifiers on your Jota are solid state and are inside the chassis. The rectifier tubes when used provide a only soft start up, so the heaters come on and when the tubes heat up it conducts and connects the high tension voltage to the power valves.
    The plugs are just potted links, this means that the ht is turned on to the valves without the delay.
    I intend to design a solid state soft start that will replace both the tubes and the plugs.
    So the way to look at this is when the valves are fitted if there is an obvious softening of base notes then fit the plugs, but if there is no problem with the base keep the valves in this position.
