Hi Chess, Wanted to set up a lab there. But 90% of my gear is 120 volts and Thailand is 230. Looked around for local suppliers but not many sources in country. Next trip there I will try to look up some local Ham's . Might give me some leads.
Looking forward to the next video. Finding this stuff locally is almost impossible, but I'd really like to find some of these old pieces to learn on. Thanks for sharing!
@@theradiomechanic9625 thanks for the comment, the nearest that I've found is about 100 miles away and they meet once a quarter. The Ham / electronics community seems to be dying off with all of the older guys that were regulars at Radio Shack back in the day. I'm 60, and you can't find a young person that is even somewhat interested unless it is the latest and greatest of whatever electronic contrivances are currently in vogue. SMH
Ive got a Barker and Williams Audio Generator from about 1959. It built much like the HP 200CD audio oscillator. I also have one of these EICO 377 units. Both have distinct functions the other doesn’t have.
I find the the 70's era Wavetek function generators do a good job. Once you get a feel for them they're not so hard to repair. Unfortunately some use custom analog chips that are difficult to find. But simple ones like the 130, 136 and 142 are all discreet component. The 136 is my bench AF gen.
For information purposes. The 4 gang/section variable capacitors were found in the earlier "EICO blue" instruments. The later models, the silver panel units, were then "downgraded" to the 2 gang variable capacitors. Patrick
Hi Doc, I wasn't expecting much. Got what I expected. This was just for the educational value. Always interesting to see how they designed things "back in the day".
Hi sir ,I have just picked the same one up, I bought the capacitor kit, I was very careful wrote down every direction of positive and neg connections, I hooked up a speaker nothing no sound, what should i look for, Any help would be great
In chapter four ( still editing ) I report that all the tubes tested like new. No shorts, tons of emission. You have to be careful testing tubes. Many tube testers have multiple errors in the tube charts used to set up the testers. I have found around 12 so far in my EICO Model 666. ALWAYS have a tube manual on hand to verify the pinout when a tube tests with a short or dead. Often it is a documentation error.
The 6X5 is notorious for heater to cathode shorts. My tube tester found it before I did. I never turn on any vintage instrument until I test the tubes.
I love your videos of this old gear - there's no way I can get my hands on any of those where I live (SE Asia) without idiotic shipping charges. These onscreen messages you blend in are hilarious - but you're too harsh on yourself ;-)
Hi alpcns. Where in SEA are you? I just got back from Thailand after 6 months there. Had my non immigrant visa, driving license etc. Came to the US to do some business and the CCP virus locked me out. Uncle Sam sent me to Thailand in 1970 for 11 months. Then Korea for 9 months. Work had me in SEA for almost 30 years after that.
@@theradiomechanic9625 I'm in the Philippines primarily, previously also all over SEA. Good to hear you know the region very well, and beautiful Thailand of course. I very much enjoy and appreciate your videos of all this lovely old and odd gear - big fan!
@@alpcns I used to have a colleague from the Philippines. Great guy. We worked in Singapore, Korea, Malaysia and Thailand together. Sadly I never managed to grab a trip to his home country. He was one of our better Tech's. Came along to learn from me and did so well I never needed to go there with him. Bright guy. Sadly we lost touch when we he changed jobs. When I get settled back in Thailand I should make a trip over and see if I can look him up.
@@theradiomechanic9625 That's a great idea. You'll love it, and I am sure he'll love it too. Many great sights and locations - it's much like Thailand in many respects.
I enjoy your videos and your teaching style. I hope that you would consider still making videos even after you move overseas.

Gotta love the $10 test bench :) Always great to see notifications of your new videos, great info!
Hey my friend. When you have a few minutes give me a call.

Hi David. You need to find the local Ham Radio Clubs. They will lead you to the goodies.

My 377 had a factory inspection stamp daring it 1965. I was 22 and in the Army, where I built my first EICO 324 RF generator.
I may not have added a BNC connector myself, but I think I would have updated the output post to allow banana jacks too.
Keep up the good work.
Mine has an RCA phono jack on the output and binding posts.

My Meccano set had square nuts. I still come across some of them repurposed on stuff that I've had for a lifetime.

The self-flogging early on in the video is amusing. ^_^
Interesting video. I've restored one of these. My front panel was damaged in shipping. Comment edited because I gave incorrect info. Sorry, Doc

Is that #53 lamp a 12v one? They are the only ones I can locate.

Dear Radio Mechanic, I heard that these 377's had cathode shorts, any comments on this?

I have this same unit, and have the same problem with the dial shaft coupling so this is probably a factory problem.
What is the purpose of that coupler versus a straight shaft.
@@erin19030 don't know
The shaft is not isolated from the capacitor. Touching it would make it stop oscillating.

@@alpcns I "m kind of looking forward to it. I watch a lot of videos from there and it looks spectacular.
I wonder if Eico bought up a bunch of factory rejects from some nut manufacturer at a clearance price. Love the $10 test bench. 73 Doug.
I think they wend for price. They work, just look funny.
The parts looks almost same as a Eico 760.
Not familiar with that 760 model.
9:15 lol!
Admittedly, Heathkit made better kits, especially their assembly instructions.

Perhaps even if the flee markets open again, without a vaccine, you should still hold your breath?
Mask and alcohol. Keep your hands clean, wear a mask. Everything that comes in the mail gets a light spray of isopropyl alcohol.
Agreed. I do the same.
You might have got away with using a piece of rubber or plastic tubing to replace that coupler. It's not under any stress or torque.
Not a bad plan.
