A search on the WWW provides following info (using screendumps).
Apparently your radio is a "Telerad D 2642 WK". Tube-combination of this Telerad equals the (Indian) "Philips 6CA65A". One may assume their structural framework is the same.
I could not find a schematic of either radio, even though Philips was a Dutch radio production company (of course also producing in other countries).
Good luck with your search!

Beste Ted,

wanneer je B6CA65A intikt in het "type" veld van de NVHR-schematheek kom je rechtstreeks bij de Philips documentatie van de Philips B6CA65A.

Dank, John.
Ik heb dat uiteraard als eerste geprobeerd, maar kennelijk iets verkeerd ingetikt, want niets gevonden.
Heb de PDF doorgestuurd.

This is the internal photo of the set.
The valve Line up are as follows : EM84 -ECH81 -EF89- EBC81 -EL84- EZ80.

One thing is new which was added later but failed some technician tried to replace normal antenna coil with ferrite rod so the Ferrite rod holder was not there in the original set.and not it is useless. So ignore that part.

It may look like Philips but the internal circuit is different from Philips radios. Actually I need the original schematic so that I can restore it as original one. All parts are fine but internal circuits are a bit hazardous. IFT's are ok All valves are fine. Transformer mains output all are working but bass trebles are not as internal circuit is been tortured by some technicians long back ago may be. Its a set of my father inherited by me.

I agree, it is very unlikely that this set has a Philips equivalent as the chassis looks completely different. The name Telerad doesn't ring a bell with regards to Philips, chances are they had their own design or possibly license from a German manufacturer. The WK suffix is often seen in German radios. Given their brand name and logo, you could see if there is a connection with Telefunken.

Dit bestand staat er al jaren, maar dan als .zip bestand. Wanneer ik zoiets tegenkom (in dit geval naar aanleiding van de opmerking van Ted) wijzig ik het in een .pdf bestand, de wijzigingsdatum wordt dan automatisch aangepast.
