Default Sony CVM-1850E

A bit of a long shot but does anyone have the schematic of the above model. I am particularly interested in the CRT type which I believe is a 470BEB22 and the similarity to the KV1800

I do know that I can buy the schematic for the US version (CVM1750) for $29.

My interest is more than academic as I hope to have one of these beasts in the near future.

Hi again,Simpsons,just realised that you are asking for the E suffix,which Ithink was the European model with different sound IF my info was based on the UB ie the British version.Hope my input is still of some benefit.Best regards,Peter.

Hi Peter

Thank you so much for the speedy response on the CRT type. Your input has saved me from making a fool of myself.

The Radio Museum spec says: Monitor mit 47cm Bilddiagonale (90-Ablenkung). Ah, good I thought. Same as my KV1800 which needs a new tube.

The Sony 1820, of which I have one, is a 114 degree CRT.

I did think that the channel change was not right but given the CVM1350 uses the original 13" 330AB22 which is 90 degrees, I had hoped I was on to something!

Although I won't be buying this for the reason given, I/we now know who has a service manual!

Thanks again

Chris

I should have explained that the 470FWB22B is also used in the Sony KV1820

Peter, I have such a bad instant recall for names that even after being introduced, I often default to the name PETER!

As for being called Simpsons "Am I bothered!!"

Thanks again for saving my bacon.
