DURING THE RECAP, ONE OF THE LUGS ON THE VOLUME CONTROL BROKE OFF. I WAS UNABLE TO FIX IT, SO I REPLACED IT WITH A GENERIC POT FROM (SHOULD I SAY IT?) RADIO SHACK. UNFORTUNATELY, THEY NO LONGER CARRY THE POT MOUNT SWITCHES (I HAVE SOME AT MY MOTHER'S HOUSE). I'LL CUT THE SHAFT OFF THE BROKEN CONTROL, CUT THE SHAFT ON THE REPLACEMENT AND SLEEVE THEM TOGETHER.
AFTER RECAPPING, I DID A SECOND SOFT START. THINGS LOOKED GOOD, OR SO I THOUGHT. WHEN I REINSTALLED THE HOR OUT TUBE AND CONNECTED THE CRT, I HAD A WAY OFF FREQUENCY HORIZONTAL OSCILLATOR AND LOW HIGH VOLTAGE, MEANING, NO PICTURE.
IN A DARK ROOM, I DID GET A FAINT IMAGE ON THE CRT. THIS WAS A GOOD SIGN. AFTER CHECKING VOLTAGE READINGS ON THE 6SN7 (HORIZONTAL OSCILLATOR AND HORIZONTAL AFC) AND FINDING THEM WAY OFF, I STARTED DIGGING AND RETRACING MY STEPS. AFTER CONFIRMING THAT I DID NOT MISWIRE SOMETHING, I TURNED TO MY FRIENDS AT AUDIOKARMA.ORG. CHUCK SUGGESTED REPLACING TWO MICA CAPS TIED TO THE HORIZONTAL OSCILLATOR COIL. I DID. NO CHANGE.
IT IS A GOOD IDEA TO BREAK AWAY FROM TIME TO TIME. IF I DIDN'T THIS WOULD HAVE BEEN A PARTS SET, DESPITE BEING SO CLOSE TO SUCCESS. AFTER A WHILE, I PUT THE CRT BACK ON. WITH THE YOKE AND FOCUS MAGNET CONNECTED, I GOT A HEALTHY ARC OFF THE TOP CAP OF THE 1B3 (HV RECTIFIER). AS I WENT TO KILL THE LIHGHTS, I HEARD SOME POPS AND THE 5U4 (LV RECTIFIER) WAS RED. I IMMEDIATELY KILLED THE VARIAC. THE YOKE/FOCUS ASSEMBLY I WAS USING CAME WITH THE REPLACEMENT CRT. FOR THE HELL OF IT, I PUT THE NEW TUBE ON THE ONE THAT CAME WITH THE SET. I CAUTIOUSLY POWERED UP AGAIN AND THE 5U4 WAS FINE. I HAD SOUND, BUT NO PICTURE.
IT WAS THEN THAT I DECIDED TO EXPERIMENT WITH DIFFERENT ION TRAPS. ONE OF THEM, AFTER SOME EXPERIMENTATION, GOT ME A PICTURE. AFTER SOME FINAL ADJUSTMENT, I HAD A WATCHABLE PICTURE. IT WAS NOW A MATTER OF ADJUSTING THE HORIZONTAL OSCILLATOR COIL AND ASSOCIATED TRIMMERS TO LOCK THE PICTURE. SUCCESS. I PLAYED THE SET FOR ABOUT AN HOUR AND A HALF WITH NO PROBLEMS.
THE TUNER NEEDED ADJUSTMENT. CHANNEL 10 (WBNS) WAS FINE. CHANNELS 4 AND 6 HAD PICTURE BUT NO SOUND. THIS TUNER HAS INDIVIDUAL SLUGS FOR EACH CHANNEL. IT WAS A MATTER OF LOCATING THE RIGHT SLUGS AND SLOWLY ADJUSTING THEM FOR PICTURE AND SOUND. WITH THAT DONE, I GET ALL THREE VHF STATIONS CLEARLY (THIS SET DOES NOT HAVE UHF).
THE CABINET WAS VERY DIRTY WHEN I GOT IT. I DISASSEMBLED THE SAFETY GLASS AND INTERNAL ANTENNA. I USED A CITRUS BASED CLEANER CALLED "DE-SOLV-IT." IT REMOVED A LOT OF CRUD AND LEFT THE WOOD WITH A NICE SATIN SHEEN. THE SCRATCHES WERE HIDDEN, BUT WILL STILL NEED TOUCHUP. THE CABINET HAS BEEN REASSEMBLED AND IS AWAITING REINSTALLATION OF THE TUBE AND CHASSIS.
I NEED TO REPLACE THE CABINET FEET. I'LL GET SOME GENERICS FROM A HOME IMPROVEMENT STORE.
