Do you mean a Model 20 fm tuner? If so and it is working, including the scope the price is below the going rate on eBay. The tuner may be either the Model 20 (that has a passive front end) or the 20b (with an active front end). The 20 has less sensitivity but is all but impossible to overload.These were essentially the 10b tuner redesigned to use ss rather than tubes and are very very good IMHO and many others opinions.

Yes, it is a Model 20, don't know if it's a 20b though. I saw it at a repair shop. It looks like someone never picked it up after it was repaired. What is the scope you are referring to? I didn't look at it that closely, but it seemed to be in nice condition - looked complete externally.Thanks for your help, Paul
never mind-went back and saw the scope you were referring tothanks again for help, paul
I bow to the opinion of the tuner god Mr. Levy whose opinion I highly value.I have heard the 20 and 20b and think they are great, but be advised they are 60's vintage and may need work.
I have had two Marantz 120's which is the model that came after the 20 that have received mixed reviews(at best). I have noticed that many of these solid state tuners that were designed right after manufacturers switched from tubes to solid state have a similar sound character. These tuners (like the Marantz 20) are "voiced" to have a rich midrange, a bit of a shelved treble and warm bass. By comparison the opamp audio sections of tuners that came after these intial transistor units sound clean but a sterile by comparison, and lack what some consider the warmer tube like sound character.
One issue that you may consider is that these Marantz units do not have meters for signal strength or center tuning. Instead they depend on the built in scope which also displays multipath. These scopes can be expensive to replace IF you can even find them. I have seen some CRT's available for the 150 and 120B but not for the (smaller) 120.
Does anyone know where to find a scope tube for a Marantz 120 besides a "parts" donor unit?
I don't think so by a long margin but thanks for the show of admiration. All of the scope tuners are decent but I think the 10 and 20 were designed to go head to head with the best of them while those thereafter were more designed to be the TOTL but at a price point that would assure large #s of sales which the 10 and 20 did not enjoy. This was the turning point when the company was moving from limited production towards the mass market. So while they may not enjoy the status of the 10 and 20 they are still very good and competitive against the other brands.CRTs are few and far between. Some years ago there were companies that remanufactured television picture tubes. I would imagine there is still 1 or 2 of these around somewhere who could tackle the rebuilding of the CRTs but it may take some research and getting to know some old geezer in a dusty old tv repair shop.
