serial number 4077
Erres 6621AT Transistor table top. With a highly polished
wood case and cream plastic speaker grille. It is a table model,
intended for use as a second set in a city home, or in places where no
power is available. Long/medium/short wavebands (800-2000 metres,
200-550 metres and 3-10 mc/s) . The first two digits of the type number
of Erres radios manufactured after 1941 equal the year. A 1 is added if
the radio is adapted for use in the tropics (or maybe for export).
Manufactured by Van der Heem & Bloemsma in The Hague, Netherlands
The radio has suffered a knock or two in its time and the dial plate is cracked and a small section of the cream plastic is chipped.
This is one of six radios which used to belong to the late Mr R M Nightingale given to me by his daughter. Roy Nightingale worked at Cambridge Instruments for many years
The two pin mains plug when inserted into the socket on the right enables the set to be powered from the five 1.5 Volt cells.The arrangement for tuning is interesting, the small brass device below the variable capacitor drive drum is a single plate trimmer which is operated by the smaller tuning knob on the front of the set.
RL.J. Gussenhoven saw this page on my website and advises that they are working very hard to finish a new website about this company. The site is very informative and some is in English. The name of the company is changed in 1940 to van der Heem NV. Bloemsma left the firm in December 1928. But they kept the name until 1940.
