These sets were a good money maker up until the past couple of years. I used to keep a rebuilt DM in stock which I'd take out to exchange at customers house to fix the steady-blink problem, then take their DM home as a core and rebuild it for next time. IIRC there were 1000uf@25v in the power supply and it seems like quite a few small radial caps, 4.7s, 10s, 22s @ 50v... those things ran so hot many of the caps showed 'dry' with the ESR meter... I'd shotgun them all and never failed to fix the problem.
