I’m having an issue with my PS-100, it works completely fine when it is connected to the amp directly.
When I connect it to my amps via a De Lisle 8x6 amp/cab switcher, the unit works when the switch is in bypass but when moving the switch to operate there is no sound. I can hear a relay going off inside the power station; is that the open load protection?
I assume that relay should flip if it detects no load, but there is already a load and it sends signal through it when its in bypass.
Yes, I agree with everything you write. It does indeed sound like the switching jack of the speaker has detected it is not connected to anything.
If this is working in bypass, then the signal is passing fine through the jack and cable. I would check the “Won’t switch to operate”" section of the troubleshooting guide, then maybe also follow the “no sound” section too. If those steps do not work, then I would recommend a service, or possibly we can continue to discuss more debug options before doing that.
For anyone who encounters this issue in the future please ensure your switchers labels are accurate. In my case attenuator in was actually the output, and attenuator out was the input.
In bypass the two were connected together so the signal went through and it didn’t make a difference, but in operate the amp was connected to the powerstation’s output. Luckily it seems like no damage occured to the powerstation since the powerstation was disengaging the speaker out( which was connected to the amp)
Does that mean my amp was running without seeing any load?
Congrats. on the solo debug, I was looking forward to a good puzzle.
If you amp’s output was connected to the power station’s output then your amp would have seen the internal resistance of the power station’s output. tubes as a load. Looking through the output transformers, it would have actually seen these as 8 ohms more or less. However, probably not good for either party. If you gave only a few seconds of signal, however, it will probably be fine. One of the plus sides of vacuumstate technology
Hi @dan, sorry I took the fun out of it for you🤣 It was a good 2 to 3 hours of probing cables with the multimeter till I figured it out.
That’s good to know! So if worst comes to worst I’ll probably need to have a new set of KT88 or 6550 on standby? And potentially and output transformer
