I own three Jolida tube amps -- the 707a, 801a and 302b. I've had them for 1.5, 4 and 5 years respectively with no major issues. The 707a and 801b were purchased used, so they had some mileage on them before I took possession, yet they work beautifully. The only minor issue has been carbon build-up in the function switch in the 801b, but that has been easy to address.
