Saba made some of the best German radios at that time. I like German tube gear, but its not the most friendly thing to work on. It is very German under the hood too. Tight quarters, overly complex switching mechanisms, and somehow excellent performance out of what would appear to be mediocre parts at first glance. The tuning mechanisms on those things are just a mess. A typical US tuner has a couple of pullies, a tuning shaft, a string, and a condensor at the other end. The German rigs have gear shift mechanisms that disengage the AM tuner when in FM mode. Some have a shift fork, some have a double faced clutch with a sliding clutch dog sort of arrangement. They have multiple tuning strings too. Don't break one, they are a mofo to re-string.
