Re: Mullard 5-10 amplifier
Hi guys,
I've swapped out quite a few of the valves to see if that was causing hum but I've only got a couple of ecc83's at the moment and I needed two for the control unit. I did try a few nos Mullard EF86's though so it's not that. When I took one side of the EL34's out the hum reduced significantly so I replaced that valve but the hum was still there.
I replaced all electrolytics and waxies. I will try a different ecc83 tomorrow.
Thanks guys
