The RGD 1046G was introduced in 1946 and was originally equipped with the Garrard RC60 record changer.
The example of this model was recently acquired and was a dilapidated wreck, the cabinet was literally falling apart. The famous twin PX4 amplifier was missing, at least the radio unit was present, some might say why bother with such a wreck?
Using all the available furniture instruments of torture such as sash cramps the cabinet was repaired, nasty chemical paint stripper used to remove the old lacquer. Hate this stuff, one whiff of it and I'm feeling quite ill.
A member of the UKVRR kindly donated a replica RGD 1046 amplifier which was made to a special order by the late Gerry Welles. The output transformer was burnt and Ed Dinning rewound it for me, a good job done. Gerry built the amplifier to the specification of the later 1046G3. This version of the 1046 employed a three speed Garrard record autochanger. Also included in the specification was the inclusion of separate bass and treble controls, these take the form of three position switches and operate in the amplifier negative feedback loop.

This console radio receiver employs a similar amplifier and radio receiver.
Also donated by the same UKVRRR member is a 1046G3 record changer motor board, this also carries the tone controls and the repositioned loudspeaker switch.

This RGD employs Mazda octal valves with 4volt heaters. By 1950 these valves could be considered a bit old fashioned, but nevertheless they are good valves, albeit a bit greedy for heater power requirement. Actually the SP41 pentode works well as a audio amplifier.
The SP25 Mk2 was bought on ebay for £20. I do have a GL75 deck but it's too large to fit in the available space, also a BSR MacDonald P182 fitted with ADC cartridge.
For the time being I'm using a 10" loudspeaker donated to me by Wilfrid wiwior en France. An adaptor board has been made because the original speaker was a 12" unit.
So now there is only a gram pre-amp needed to finish the job.
