CJ's are like fine wine... better with age. You might end up in utter disappointment. I would keep what you have, unless of course there is a 'space' problem now. The idea of an 'integrated' is a good one. I know it isn't new, but you might consider an old Mac 5100 if tubes are a must. Very sweet sounding integrated, and Mac still services them.
Nothing like owning and enjoying a 'classic'.
