F R E E It is in great shape too. Gotta start somewhere. Unless someone wants to donate a 1076 or 1077 to Big Al's charity??

I'd have to blow the dust off of my 1077. Used it all of once....to make sure it worked
Of course the moment I need it......

That's b/c for some strange reason your sets never seem to have signal issues. You get hot plating HOTs!!!

There's a fellow over on ARF that swears by his 1075. I think as long as it's serviced and up to spec it will do well. But do yourself a favor and test it out on a more modern CRT TV first.

We used a 1075 in the TV shop I worked in in the early 80's. It was a good piece of equipment and never let us down.

I had an 1076 that I had back in '88 that used to belong to where I was working at the time, sadly it no longer exists.

Replacing the interstage micas is a no no unless you want to do a full IF realignment. I have restored a number of RCA sets from 46 thru 52 (before RCA succumbed to cost cutting) and have never found a bad interstage mica.
The realignment is more complicated on these sets and you'll need a good sweep generator and accurate marker to do it right. Split sound sets like the 630 require the job to be done right because of the audio video tracking when tuning. Split sound sets are tuned for best sound and not picture. When aligned correctly the picture quality is the best on RCA sets. No expense was spared. But patience and perseverance will now be required to bring the alignment back. |

An oscilloscope is your friend.
Get one and learn how to use it, and this problem will be solved in 5 minutes or less. |

A sweep generator, a marker generator and of course an oscilloscope. All three are required to properly realign the IF strip.

Any chance the original mica's were kept so you can revert back to square one?
I think it's unlikely that replacing those inter-stage mica's would completely blow the picture off frequency. |

Do I need to bring my alignment rig to the meet and do some teaching?

That's a good idea Nick, I'd like to be there for that as well but am stuck in Wisconsin this year.

Good old Davey, didn't want to pay Motorola the royalties. He just liked collecting them. I have to get back to my 621TS, haven't touched it in months! |
