I think the tube looks pretty good. If it ever went out though, I’d gladly sacrifice another 12” Sony to save these. Not only do they have dual composite in and a composite line out, but I feel the RF looks much better than on other comparable sets from the same period. Composite and RF seem nearly indistinguishable.
Having these professional electronics combined with the beauty of a KV-1220 cabinet is what makes this set my favorite.
