New amp no sound at all. Powers up silently. Any advice?

Take/send it back? Call the seller to see if there's something potentially odd and/or make arrangement to return.

That's what I'd do, but first see if there's a "standby" switch on it. T

hat's typical for valve amps to allow them to be "on" but not putting out any sound.

Solid state amps ain't usually having one of those switches. Lots of valve amps, if not most, tend to have them.

Long story. Didnt try it out until too late. It does have a standby switch but it makes no difference. DSP mute, poweron ON and foot pedal lights light appropriately. Tried swapping fuses.

None of the tubes glow or warm up. Nothing from spkr. Pristine with back off. No sign of external o internal damage. Could a single bad tube cause this? I'm thinking maybe the power supply?

Should I just turn it over to GC? I'm not the original owner. I'd use it as an extra 12in spkr cab but I'm already using a broken EP1000-R for that purpose. BOO!

Hey Donald, sorry to hear about that :( Can you pull the chassis from the cab & post some pics of the guts?

Built into the power socket (underneath where the lead plugs in) is a small fuse drawer.
Bet you a pound to a dollar that the fuse has blown (most people miss this fuse)

**EDIT **

Missed the bit where you said some of the lights come on.

In that case it could be the standby switch has burnt out (Epiphone amps are quite notorious for this).
My current Setup:
Genevieve - My Epi Les Paul Standard in Natural fitted with BB Pros
Dot Studio in faded cherry with GFS Mean 90 in neck and Gibson 57 Classic in bridge.
Home built 52 style tele with matched custom wound Bare Knuckle 'Yardbirds'
Epi BC30 fitted with NOS '61 RCA Blackplates and a '59 Mullard GZ34
Strat style bitsa affectionately known as the plank
Korean Tanglewood TW400N acoustic
EJ200CE Super Jumbo
AXL Player Bass

Very little talent & big dreams!
