I vote no. There's not much to mod, maybe 6 film caps? That's about it. I wouldn't mess with the electrolytics. The limited factors in any tube amp are going to be the circuit and the output transformers, maybe the power supply if it's really inadequate, which I don't think is the case here. It is what it is. If it's gathering dust, sell it and use the money for something you can use. ;-)
Is It Worh Modding An Amp
I have a Primaluna Dialogue One that sits idle as a backup. I’m debating the idea of having it modded. Problem is I have no idea what can or should be upgraded or if the amp is worth the investment. Id be willing to fork over 500-1000 if it was worth it and made sense compared to what else I could do with the funds. Curious what people’s experiences and thoughts are?
