Dear All - What tube improvements can be made to Stax007tA over the stock tubes? Are matched pairs available or is there any change needed to be done to the board? Also any recommendation on exernal PSU to improve SQ? Thank you

Thanks so much Kevin for your response. Would you suggest - its still feasible to source and replace all of them. From cost point of view - would it be a major overhaul. I live in india and still searching for a Hi-tech service stores who can repair it. Kindly advise.
