I was playing a gig on the weekend and when I was setting my amp up I switched it on but no light came on. At first I thought it was the power cable so I swapped that out with another but still, no light.
So the sound guy and I decided to run it to a different power point but still nothing. In the end I switched the power point off and on again and then suddenly I had a working amp. It didn't miss a trick for the rest of the show.
Anyway... I was a bit suss about it so I plugged it in again the next morning. Nothing. I try different points in the house and different cables... nothing.
When I switch the power on I can hear the slight hum of the transformers getting power but no light comes on and, from what I can see, no tubes glow. It just seems dead.
I checked the mains fuse and the HT1/HT2 fuse and they look fine. I even swapped the mains fuse out with a new one. Still nothing.
So it is going into the shop next weekend but in the meantime I thought I'd see if anybody had experienced something like this before. I am dreading to think it is the PT that has died. It was recently serviced and re-tubed and worked fine the last 3 weeks. When I went to plug in at rehearsal the week before I thought I felt the IEC connector move more than it should but when I opened the amp up everything seemed fine (possibly something has broken there that I didn't notice...).
Anyway, I'm at a bit of a loss.

Re: Orange AD200 - Can hear the hum but no power
It sounds very similar to the issue I had with 2 of my AD15. I haven't seen the schematic for the AD200, but for my AD15, the pilot light and valve heater circuit is the same, except for the GZ34 which has a different tap with slightly lower voltage.
In my case, on both my AD15, the 1st splicing connector directly after the transformer sort of burnt out and left carbon residue on the splicing contacts. So the valves heaters for the 2 ECC83 and 2 EL84 weren't getting any current, and no sound was coming out. In both cases, with the help of this forum for the 1st amp, I removed and clean all the splicers and hardwired the circuit with 2 amp/230v electrical wire. Soldered that to the splicers spokes and done.
I'll try to find a link to my 1st amp issue thread. People on this forum were great at helping me out diagnose the issue.

Re: Orange AD200 - Can hear the hum but no power
That does sound very similar. I had a look at the wiring in my amp last night and can confirm the heater and lamp are all on the same circuit.
I'll have a read of your original post. Thanks heaps!

Re: Orange AD200 - Can hear the hum but no power
This was the problem after all. $60 bench fee and I'm back in action. Thanks so much!

Re: Orange AD200 - Can hear the hum but no power
Glad it was just that!!!!
Those splicing connectors really are crap though, and a seriously weak construction point in terms of long term reliability.
I think Orange started using better connectors at some point.
What did your tech do? Removed them all and hardwired them?
I'm tempted to do that preventatively to my Rocker 30.....

Re: Orange AD200 - Can hear the hum but no power
He told me that the connector had failed and started to arc which desoldered it from the circuit. He removed them and hardwired the heater circuit. Technically it was a job I could have done however I love this amp and my life so tend not to mess with it (I restrict myself to 9v pedal circuits )Les Paul Lover wrote: ↑Tue Sep 10, 2019 6:12 amGlad it was just that!!!!

Yeah I would feel that if those connectors are in your amp it is worth getting them out.
