Lately, when I use my PS-2A as a Power Amp (with preamp unit in front), which is how I use it 90% of the time, I get these intermittent volume drops, then spikes back to normal volume, almost sounds like it’s “farting out”, for lack of a better term. I’ve had my unit (bought new in December, 2024) for 3 months and haven’t had this issue until this past week. There’s nothing else in my signal chain - just the guitar, into a preamp unit (in most cases an Origin Effects Revivaldrive compact), and then into the Power Station Line In. I sometimes put a boost in front. I isolated every cable, pedal and speaker to make sure they weren’t the issue, and double checked my impedances. I thought it may be a tube issue, but I can’t notice any red plating, and they have been used for about 10 hours at most (still has factory tubes). I’ve emailed Support as well for advice before taking it to a tech, and to avoid voiding the warranty.
I love the unit as a power amp and as an attenuator/silent recorder. Any guidance would be appreciated, Thank you!
Sorry to hear about this issue, where are you based approximately? Should we continue here or are you already being helped by Gil?
Firstly, thanks for describing your setup so well. It eliminates a lot of my questions. The only thing I can think of other than an issue with the unit is a bad cable that is making intermittent contact.
How frequently does it Fart (new technical term )?
If feasible, dependent on the Fart frequency, can you eliminate bad cabling? I know this is easier said than done. Maybe wiggling cables ?
If you have a spare 12AX7 you could swap that in.
If you have spare 6L6s you could swap those in too, afterwards.
Fryette warranty tubes for 90 days, if seems you are right on the edge. It might be still worth doing a parts request if those turn out to be the problem. You can see what the factory says. Check the FAQ section for how to do that.
There are some options and things to try, is that a reasonable way forward?
Thank you for your quick and thorough response, Dan. I really appreciate it!
I’ve been in contact with Gil and we’re working on it. I’m waiting for a new set of 6L6s and will swap them out. Seems like that’s what might be the issue.
I’ll report back here either way when it’s all resolved so it can hopefully help those with a similar issue in the future.
Thank you guys again for your help and quick responses. Love my Power Station.
