Advice please on valve amp issue
Hi guys a freind has a Mastersound compact 845 amp with B&W 805d speakers.
He is slowly losing volume when the amp is on before it cuts out.
I was wondering if any of you valve experts know what the issue could be before he sends it off for repair.
He would like to try crack it himself as its mid Jan before the guys can fix it, so no music over xmas for him .
He has tried changing valves but still happens
Thanks
Karl
