Hi everyone


I recently purchased a Blackstar Ht1R and I noticed that it produces a dull / dark noise right after I switch on the amp. It only lasts for about 10 seconds and then it disappears. This also only happens if I haven't use the amp for a couple of hours.

Any ideas?

Thanks.

Change the tubes, check the fuses, check if anything is visibly damaged (blackened for example) inside the amp.

Clue: amplifiers amplify so don't turn it on if you need quiet.

It’s probably just the preamp tube warming up. Tubes have to be hot to operate properly and it takes them a little while to warm up after they’re first turned on.

That's not the sound they make when they warm up.

They don't make any sound when they warm up, the volume simply raises.
