Help Old Radio Philips

[ervinl]

Hi,

I have old Philips radio with phone/amplifier inputs. The type could be 483X-05 (not sure due to letter is not clear), NR E10999E00.

Anybody has this schema?

I would like to refresh/change the tube. The rect tube pinout is similar to AZ1, but the type is not clear (almost gone). Should have higher rating than AZ1 (but what tube type?).

The power tube is EL3??. I guest EL34, but it is wrong since the pinout (socket) is not octal (although 8 pin), almost like AZ1 (4 pins wide space, 4 pins short space). Seems like EL3, but not sure since there is additional number/letter after that. It is Miniwatt.

And about driver, somethink like EBF??. With a cap.

Thanks,

Ervin L

Hi:

Try contacting the American Radio Museum in Bellingham, Washington. They have at least 10,000 different old tubes and lots and lots of radios, parts, and expertise from a group of volunteers that really know their stuff when it comes to radios.
There website address is: American Museum of Radio & Electricity

EL3N I think.
AZ2(120mA) and AZ4(160mA) are stronger tubes than AZ1(100mA), with same socket connection(pin-compatible).
For 1xEL3N as an output tube, You need AZ1. Your AF-driver is EBF1.

As it seems to be a European design you could try asking here, but better pictures might help.
