Murphy A574
The
Murphy A574 is an a.c mains valve radio with long, medium and f.m tuning.
It was made in 1959, and has press-button wave change switching.
The valves used in this receiver are:-
6L12, 6C12, 6F18, 6LD12, 6P15, EZ80, EM85.
The EM85 is now quite a rare tuning indicator valve. The one in my receiver
had seen better days, so a hunt on the internet eventually tracked one, the
last one in stock on one site. The resistor that connected the T.I was also
replaced. Not many resistors required replacement in this receiver, but the
capacitors (plastic coated Hunts) required replacement.
The control knobs were totally incorrect for the radio, more suitable for
a hi-fi system. It took an awful long time to find the proper knobs. They
were eventually sourced from two different suppliers (both sent me one good
and one broken one). The plastic used on these knobs can not be repaired by
any method, very poor quality! I used grease on the control shafts and the
knobs to ease application & possible future removal.
The grille cloth over the loudspeaker required replacement, as it had shrunk.
I had some left over from an earlier project, so that was utilized.
The edging of the cabinet front around the loudspeaker and tuning dial was
in a poor state. I sprayed it in black primer, and then in a gold finish.
Looks very good!
A neighbour donated this receiver to my collection. It sounds great now, with
its large elliptical speaker.
