Hej alle
Er der nogen her i gruppen der har erfaring med genoplivning af r�rradioer?
Jeg har f�et en National NBS-1, hvor flere b�nd er d�de. Et b�nd er ikke d�d
men uf�lsom, s� det vil om ikke andet sige at mellemfrekvens og hvad der
ligger derefter er nogenlunde ok.
Radioen har r�r med Octal fatninger.
Jeg har ogs� en anden modtager, som kommer fra DISA og som har v�ret
installeret p� Georg Stage.

Hi all
Sorry I wrote the original message in danish !

Here is the englis version

Anybody in this group having experience with revival of tube radios?
I recentlly got a National NBS-1, where several of the bands are dead. One
of the bands is not dead but insensitiv, so that should mean that the MF and
what comes after that, should be ok.
The radio has Octal sockets.
The radio is probably from 1948. I suspect that some of the parts, in
particular the capacitors, are so old that they should be replaced. Would
anyone have some good hints?

73, Nico (OZ1BMC)

The days or repairing electronics are over except by
sending the unit back to manufacturer.

PS Have gotten my Yaesu FT-2000D repaired but I had to ship
it back to Yaseu in California.

That's completely wrong.

1) Repairing old equipment is not so difficult providing you know what you are doing... and
2) The OP has little chance of sending a 1948 piece of gear back to the probably long gone out of business company!

Electrolytic caps will probably all need replacing

All switch contacts cleaned

Check insulation of all cabling and rewire where necessary.

Check all valve fils light up

Good luck...
