I have a similar model, it ran great after I fixed it, but just last saturday the vertical colapsed:shock:
I still need to locate new tuning and volume knobs for it.

PS. macrovision never affected the synch on mine, and be careful not to let the H osc get too far off frequency because mine eats dampers when the frequency is too far off (I hever expected the damper to short, and this led to months of confusion and chasing my tail untll I noticed intermitant arcing in another sets damper and the only spare at hand was the blown one in my Silvertone).
