I think it was an xsm 10k:600, although I'm away from home at the mement so not too sure.  People have said it isn't specced for the d.c but it worked fine while I was testing it,  I then swapped them for the Sowter.     I have experimented with a gain cell using  4x 6bc8 in parallel with that edcor too & that worked well & sounded nice.
Danke

by engaging the bypass switch relays dont "click"

EDIT: this is just a reminder, nothing to do with th relay ctrl, i just bumped that here again, someone asked me....don' forget to check that the Frontpanel PCB' are connected to Gnd, there are pads for that, to use Faston or hardwire.

Also check if the hardwired mods are still present under the board, and that the Relay Diodes pre-installed have some pins connected to gnd on Top Copper.
Just to take out that part, as i double check on sending but again who knows... shipping /handling could have fragilise the solder links of the hardwiring or whatever...
Anyway, check to take that part out of the way, if the Supplied voltage is accroding to your Relays min/max Voltages and if the Ribbon wiring etc... is all good, then there should not be any problems on relay clicking.


Best,

Thanks Volker, BOM Updated with available parts. on PSU BOM, dunno why these were in the MB+CTRL BOM.


Don't hesitate to post here if some parts are obsolete or missing or whatever from the BOM.

Best,

Hey everyone ! A lot of the parts refs from the BOM were unavailable or with hundreds minimum qty order so I made a Mouser basket with new references :

Motherboard + controller boards : https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=479778172f

PSU board : https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=a8776b7727

I will order and check soon but for now don't forget to check yourself !

Peace

Oh and there's multiple options available in the basket so you have to choose like the relays or you'll end up with a lot of spares
