Dear all,

Thank you for your kind response regarding troubleshooting of Philips 483x tube radio.
I had bought nos ech3 tube as ech4 tube replacement. Then i rewired the tube connection, now the radio has reception (although broadcast band only). The used ech4 tube has weak on heptode section.
Well, it is no warranty if used ech4 tube will work properly eventhough the tube seller had said tested on funke tube tester.

Again, thank you very much.

Best Regards,

Winstony
