OK a little more on Sams crosses.
#847-1 H1-1A & H2-1A Nov 66 #894-1 H1-1A, & H2-1A added 1H-1A & 1H-2A July 67 Missed the other, must be my eyes. I probably got that too. Both mine show a 3GK5 NOT a 3HA5 for RF amp so you may have a newer one with different tuner assy. 73 Zeno LFOD ! |

Update: It's lost all horizontal now. I think I'm gonna look into getting the Sams for it, use that to try and poke around a bit. If that fails, I'll use the shotgun approach.

The 1062-1 probably the right one. See if you can
find a free one first. If not get back to me. DO NOT buy it from Sams. Will be a shitty PDF of photocopy. I have high quality originals. for 1/4 the cost. BTW these had a lot of bad yokes. Often if you pull it off the CRT it will start to burn & prove it easily. 73 Zeno LFOD ! |

IIRC, that set had an SSKresge logo on the speaker grill. |

Although he pissed me off because he shortchanged me on some car repair I did for him. So in my book, he owes me a $150 favor. But I might take you up on that offer. Also, the yoke looks pristine, it was the cleanest part of the whole ratshit-covered set. And I've taken it off but not while it was working. But now that you mention it, don't they have capacitors inside of them? Maybe I'll crack it open and check the resistance of the coils anyhow. |

A small update. I dug around in my tube box and found 4 empty boxes of the 33GY7A, and one occupied one. I also found a 23Z9, so I just plugged both of them in, but no difference was made.
Also, literally burned myself on the 23Z9. I'll get back to this project for realzies shortly, I've been working on that radio. |

Capacitor question #1:
The polystyrene(?) capacitors - those clear plastic ones - are marked in 4 digits plus a letter. ie - 6800K. I assume that's 6800pf with K tolerance. But then just one of them is 560K, 3 digits. So is that 560pf or 56pf? Capacitor question #2: The giant cardboard can capacitor's ratings are toleranced as follows: 200-250uf 120-200uf 100-150uf With math, I propose the following: 225uf +/- 11% 160uf +/- 25% 125uf +/- 20% Which, obviously, are very odd numbers. So should I use the minimums, maximums, or go with the oddball middle values I calculated? Last edited by MadMan; 01-27-2017 at 03:08 AM. |

I'm pretty sure that would be 560pF. Those are very stable capacitors and probably don't need to be replaced.
I'd go with modern standard values of: 220uF 150uF 120uF |

Dude thanks. Someone else though, mentioned that when the plastic cracks on those polystyrene ones, that they start to go out of whack. And they're all cracked. Idk, besides the can and the polystyrene ones, the rest of the caps are brown dips and ceramic. Original, obivously, but I'm hoping one of those little ones and/or the can will take care of it.
