Valvulator 1 making white noise after about 20 minutes

I’ve had this unit since the late 90s. I’ve had the transformer replaced. I recently played a show and during sound check it started to make white noise and basically stopped working. I assumed it was a tube but after 3 tubes I suspected there was another issue. Each time after about 20 minutes it jus stops working and makes white noise. I tested my tubes to be sure and I know It’s not tubes. I’d to send it again like last time if possible. I believe it may be aging electrolytic caps but have no idea what the problem is. How do I get support for this unit and possibly an RMA to get it repaired?

Hi @Rolteus and welcome to the forum!

I remember Steve mentioning that people love these things and even by multiple units just in case. There is a new Valvulator Mini coming out soon

Anyway, to answer your question, yes for RMA check this out: How can I send my product to Fryette for a repair (RMA Request)?
