RPM "Melon."

The Meiorca is designed tor operation from
200-Z4OV 6013/: mains power supplies, with the
same limitations that apply to model RH 99
(see overleaf).

This raproducer has a miniature jack fitted

enabling a tape recorder to be connected (via a
3-5mm long shank lack plug) for both record and
playback. it presents an Impedance of approximately
20m and a sensitivity of approximately toomv

for both conditions

Aforwsrd facing sin by 5in elliptical loudspeaker
handle: an audio output power oi 3W.

Trenalnor analvels

Transistor voltages shown in the table below
were obtained from information supplied by the

manuhcturors and they are all negative with
respect to positive line.

Record changer

The automatic record changer is the Gerrard
model 2025 which is fitted with a loiin die.
turntable. An Ace: GP91 ll SC p.u. cartridge is
fitted, the recommended stylus pressure being
6-89111. The ou. is mono/stereo compatible and
will track satisfactorily on both mono errd stereo
records without damage to either.
