'66 Motorola color console, 19" CCII, & '83 Zenith console found today

[radotvguy]

be very careful when removing a safety glass . I had a crt implode right in front of me . Lucky for me i was wearing safety glasses, gloves and was not hurt . However it taught me a lesson on removing a safety glass . I found soaking the crt face down in water for a few days works fine . I never try to remove the safety glass with heat after the experience i had .

In my case Experience, Look around for a tube substitution book and it will show what can be interchanged by part number.

I've also read that the 23EGP was obsolete early and that special changes had to be made to fit...but then, the other day I was browsing a Channel Master substitution guide dated 1969 and they were still available. I guess some models were easier to sub than others. A lot of those Motorolas were unique in that the crt was removed from the front. I'm not sure if that makes it easier or not. I also remember a member mentioning that this tube was prone to implosion, but I took most of what that person said with a grain of salt.

I don't know what I'll end up doing with it. Most of the general public wouldn't have it if I gave it to them. If I gave it to the thrift store, it would just sit there forever with a $100 (or higher) price tag until they got tired of it sitting there and dumped it. I gave the last console I had to a needy person; and, they actually appreciated it. If I strip it, I'll keep you in mind on the parts. It really needs a new CRT to play really well. This looks like a very high hour set. This set uses the tripot tube that was used in the earlier system 3's. In '84, I think they went to the newer version inline tube that's still used today.

Thanks! You don't have to cannibalize her on my account but if you ever do, I'm always looking for parts if they will match.

I just obtained a B&K 606 tube tester (in good condition) and decided I'd try it out on this TV. I found the following tubes that were shorted or had excessive grid emission:

6AW8A
6BL8 X 5 (6BL8's must have been to Motorola what 6GH8's were to RCA)
6GH8
6EH7
6EJ7
6HQ5
6HB7

Now, I've got to raid my tube stash and order what I don't have.

I must have missed this thread the first time around. I have one of those CCIIs.



A great performer. Has been in my unheated garage for several years now, and still has a beautiful picture.

Well, I'm sad to report that the Motorola went to the dump today. Let's just say that there was a big blow up here concerning the amount of "junk" that I have. I know Motorola's are not highly regarded by old TV techs; but, this was sort of a cool set and who knows when, or if, I'll find another Motorola. Not counting this one, I've had four over the past 20 years: A beige metal cabinet 23" tube color set, a late '60's 23" console color set, a late '60's "works in a drawer" SS set, and an early '70's 17" color hybrid portable. They were not near as common as Zenith's and RCA's. Probably because they didn't last as long. I also had to toss a Zenith flat chassis solid state 25EC58 space command color set. That one had tuner trouble and then developed horiz. sync issues. It was in a huge particleboard and plastic cabinet that was not in the best of shape. I also tossed a bunch of '90's BPC. I dumped a modern Symphonic 20" DVD/TV combo that I've been sitting on for 2 or 3 months waiting for a CRT. The original CRT had a damaged shadow mask. I'd been back from the dump about 30 minutes when my cousin showed up with a nearly identical set with the tube that I needed. Just my luck.

Anyway, I don't think the sets went to total waste. A man and his young son pulled up at the dump in a beat up Ford truck loaded with old appliances. He asked could they have the TV's. They didn't look too well off and both of them thanked me for the junk. If he could get enough copper out of them to put food on his family's table; then, so be it.

I'm going to have to stop trying to rescue everything that comes along. If I continue to pick up TV's, they will have to be smaller portables. Unless, of course, a roundie comes along.
