Re: Kolster Brandes RV 10 (Crown)
The RV10 was a popular rental set, it was in fact made for that purpose. I remember the set well, very reliable and easy to service. Before you fire the set up I'd replace all those waxies in the frame timebase. Clip out the mains filter capacitor, it can be replaced later. Also replace the boost capacitor C63 (0.1mfd 500V) and C65 the A1 supply capacitor.(0.05mfd 1000V). These capacitors are easy to find, they are on a tag strips near the aerial socket.
I serviced a KB QF80 way back in 2011, this 21" set is similar in many respects to the RV10. I might be possible to search the forum for the restoration of this set.
Information for the RV10 can be found in the 1960/61 Radio and Television servicing book.
