I'm assuming this is a OneSpot Pro CS series supply? If that's the case then it should be fine as the labels on the outputs don't actually correspond to the maximum output available.I recently picked up a used Space Heater and a Finally... do I qualify for the Secret Society now? I ran out of power cables (poor pedalboard planning, LOL) so I haven't used them together yet, but one at a time, at low gain, they're giving me exactly the warm, full tone I've been seeking for a long time. Big fan, total convert.
But... I'm having an issue with the Space Heater that makes it unusable, and I'm looking for advice on what to troubleshoot. It keeps "cutting out", not completely, but like with an ~80% reduction in volume. This happens for maybe 5-10 seconds at a time, then it'll be good for another minute or two, then another few seconds out. It happens long after any warmup period. Where do I look for causes? Am I underpowering it? It's in a 200 mA @ 9V plug in a OneSpot power supply, so it "should" be able to get the recommended 250 mA. Do I need "the fix" for polarity or something? Could the tube itself be going bad? It is not that old (August 2022), the previous owner seems very trustworthy and says they did not have a problem with it. When I use the Finally in the same position, just as a gain and ignoring the DI, it works great. Any troubleshooting advice appreciated.
That does sound like a common symptom of a tube on its way out though, do you have another tube you could try swapping it with? That would be the first thing I would take a look at. If you've tried another tube and that doesn't fix it shoot me a PM or email and we'll get it figured out.
