Likely cost you more for those than what you paid for the radio. Yes, while the ones in the unit work, I did find several online vendors that have "tube kits" for the SX-24/25, not too bad of a price, ~$65 to replace all the tubes. Might buy a kit just to have when one finally goes. They do get hot, noticed to top hinged cover had some black scorch marks from the tubes that get the hottest.

Lscott Posted February 6 Report Share Posted February 6 I remember the old TV's with the "instant on" feature. The tube filaments were powered at reduced voltage when the TV was "OFF" then the full filament voltage was applied when it was turned on. Since the filaments were already near operating temperature it didn't take long for the TV to be ready. This also increased tube life due to the reduced thermal and mechanical shock between cold and hot filaments. WRXB215 1 Quote Link to comment Share on other sites More sharing options...

I can remember, as a kid, impatiently waiting for the TV (black & white) to warm up so I could watch my favorite shows.
