Well, no luck on first power up. I installed a 1A fast blow fuse and it blew right away when I powered it on. The sticker on the radio says it consumes 60w, so I thought this would be sufficient. Does a typical radio draw more current at power up than steady state?
After the fuse blew, I changed the fuse and put a 100w light bulb in series with the hot leg on the AC cord. When I turn it on this way, the bulb glows brightly and continuously, but the fuse stays intact. If I power it up without the rectifier tube, the bulb stays dark.
How do I differentiate a bad tube from a problem with the power supply transformer? All of this presumes I didn't goof something when recapping and rewiring...
Any good places to start diagnostics?
Thanks,
Eric
