Hi Kyle,

Welcome to the Forums.

There appears to be two versions of this model. The TV section in one is all valve (Series 8) & the other hybrid (Series 11).

Are you wanting to service the entire unit or just the radio/gram section?

Any service information can be sent here as pdf file.

I have the Series 8 and Series 11 TV chassis schematics if you want them.

Also a lot of memories about both those chassis! If you have a Series 11 with the Anodeon transistors (early production) you probably have an unreliable unit, unfortunately. Although I used to fix 'em when new, under warranty. Maybe the bathtub curve applies!

If the middle PCB has no valves you have a Series 11. Else it's a Series 8 with Decal (10 pin) valves - 6X9, 6U9, 6Y9. They will probably need replacing, they were not a long-living valve series either in production or in service!. Not hard to get though. The 6JW8 will be OK.

The valve tuner had an issue with a 22pf ceramic cap changing in value, affecting the band 3 tuning. There is a 4.7k 1W Ducon resistor that would go low ohms and chop out the 6HG8 mixer/osc. prematurely.

Hor osc tuning cap would go intermittent O/C when cold, resulting in no drive to the 6CM5 which would be damaged if left too long. You have to replace the cap with the right type.

Apart from that, not much would go wrong with them!

I think the Series 8 version was also known as a Astor Royal RG52/8-DB. Astor did change their model code system around 1968.

The radio/amplifier section has 5 valves, though the valves & chassis type is unknown. Nor is it known if the later versions were solid-state.

Astor must of known that some batches of their Anodeon transistors were crap. The Series 11 addendum sheets suggest replacing some of the Anodeon transistors with Philips types. Astor claim that this was for supply reasons, not quality issues!
