I’ve got a Longdog phono stage which has amongst other valves has ECC88’s.
I was advised on purchase rolling was worthwhile, so I’ve got Russian Silver wire Reflector.
While I think they do sound better, I’m getting an intermittent blip/static in one channel and there is more noticeable hum compared to the Amperex Bugle Boy’s.
Is the extra noise a result of buying cheap/unmatched/ counterfeit/russian/shite * or do they need running in? As far as I know they’re NOS.
*delete as appropriate.
I’m keeping the Paradise, so this is a learning experience rather than searching for the ultimate set of valves.
