I've got a HT5 head, when i switch power on I get a hum out of ther speaker then after about 30sec I switch on standby but i get no sound throuh the speaker and the hum disappears.
I'll switch the standby off then wait a further minute and try again still no sound, standby off again then wait a few seconds then back on with standby and its on and working. sometimes this whole process can take up to 5 minutes to get the amp on and working. Both tubes are glowing within 10 secs of powering on. Could this be as simiple as the standby switch, also the Emulated output doesnt work in standby mode should this be the case. I'm not sure of the age of this amp but it does have the newer style main PCB.
