Default Philco A547B radio valve positions

I have a Philco A547B valve radio. Could anyone tell me the positions on the chassis for the two valves Brimar 5Z 4G and Ferranti 6V6G please?

I know they are located next to eachother but do not know which way round they should be!

Many thanks.

Right. Manual available up top there and well worth getting.

Valves - From the back, there are 2 near the transformer. With the back off and looking in from the back, the back one of the 2 valves is a 5Z4G. The 'front' one near the back of the chassis is a 6V6G.

The other three, counting away from the mains transformer, are 6Q7G, 6K7G and 6K8G.

Cheers,

Steve P.

Hi Steve,

Many thanks for the fast response.

So, if I understand correctly, the valve closest to the radio's rear cover is the 5Z4G, while the one closest to the speaker is the 6V6G?

Many thanks,

Oliver.

Other way round. The one nearest the back cover is a 6V6G. The one in the middle is a 5Z4G.

Cheers,

Steve P.

Just a foot note to the above.
I 'did' one of these about a month ago.
V2 has be a 6K7GT not 6K7G.
As there's no screening can round any of the valves, you get some pretty strange results by using 'G' versions.

Good luck
Pete
