Is it single-ended audio outputs with dissimilar output transformers? Speaker complement? Schematic?

It's great watching YouTube videos without being pummelled with ads before each one. I've had my own custom hosts file for so long that I never knew about the ads. I also have uBlock Origin plugin installed in Firefox, this kills off lots of unwanted popups and other rubbish, although it can be a bit aggressive at times.

They feed the pre amp cathodes with B+ 120k/470 resistors (bias?). One of the output transformers has been changed to one with different secondary (old one burned out due to leaking coupling cap?)

Gorgeous Pete, nice find, there was one of these in a second hand shop in East-Murray Bridge a couple of years ago when I found my Philips 224 Radioplayer. Might still be there?

Jamielee, Hello, Thank you, yes I really like this model and I have wanted one a long time. Its in pretty good condition and hard to find complete and not fiddled with as as many are. These things that we love and are always looking for are often in great condtion if we are lucky enough to buy them from the generation that bought them new as I did with this one, That generation looked after their things . All the best pete

Wa2ise, Hello I think I have chatted to you over at Antique radios about TVs? Thanks for that.! Kevinchant is doing a great job with that site making schematics avaliable for free down load,,I think thats just a great thing he is doing. NewVista I think it would be single ended but I have not looked at the amps or the schematic,,i will have a look to night. All the best ,,pete

One of the output transformers has been changed to one with different secondary (old one burned out due to leaking coupling cap?) Yes I can see one is 7000/2 k9 5 made in 1960 by Rola, the other is 7000 / 3,5 E2 1965 made by Rola. I dont know if they are compatible or not ?? I will have to read up and learn more about them and what effect it might have ,,both speakers are the original 2ohms,, Rola, the chassis still has its original paper caps so I have not turned it on yet. I will replace them and start from there. All the best pete

I doubt if you would hear any difference with replacement x-former, so close it doesn't matter.

NewVista Thats good to know thank you, Its all original apart from that one Amp repacment. Its hard to find any Radiograms 100 % original as their getting very old now,,This one is getting close too 60 years old soon. At the moment I'm rebuilding the Garrard Rc 121 Turntable in it. Its coming along good, Turntables are not a problem for me because I have done a few before and I have a mechanical back gound, but I'm still learning electronics and learning as much as I can along the way regarding electronics. All best ,,pete
