All Dry Battery Only 4 Valve 2 Waveband
(Serial Number B 2708)
The R77 is a 2 waveband four valve (DK96, DF96, DAF96, DL96) portable
receiver employing a ferrite rod internal aerial and printed circuit board.
The wavebands covered are: M.W. 190-570m and L.W. 1,000-1,900m.
Originally released in May 1957 it cost £13. 4s. 7d. including batteries but purchase tax was extra.
The one for sale is excellent condition externally and internally with clear dial markings including all the stations on the slow motion tuning.
The real leather binocular case is in great condition, the two zips are operating nicely, the dial is clean and bright, the three knobs are original and in excellent condition, the brass fittings are bright and untarnished and the small front grille is clean and undented.
The leather shoulder carry strap is complete with all of its original stitching.
It is a complete and original radio set, very clean internally and externally. This is a more than 57 years old set and some age related marks should be expected.
I have provided lots of clear close up photos of this radio, please enlarge them in order to see the cosmetic condition in detail.
As not many radios of this model were produced the R77 became extremely rare and even more rare is to find one in this remarkable condition and working order.
This is a 'must have' radio for serious radio collectors and comes complete with a colour copy of the original Roberts R77 Booklet and a copy of he Trader Service Sheet.
The radio is working on both wavebands but requires a 90 Volt HT and a 1.5 Volt LT supply (battery eliminator) as the correct batteries are no longer available.
It has been fully tested using an Amplion Convette battery eliminator and is working well on both wavebands.
