Fan installation in a Wavetek 3001 signal generator
Просмотров 276Месяц назад
These series of signal generators have a bad reputation for not being very reliable. I installed a fan in one a number of years ago and it's never broken down. I recently acquired this one and decided to install a fan in it also. In this video I go over how to install a fan and how and where to mount it inside the signal generator.

I ordered a couple of sets of blades for my Philips series 1000 shaver, and they had notches sticking out of them so they didn't fit. I cut off the notches with a pair of side cutters and they fit perfectly after that.

Nicely done Frank! Keep it up!
Thanks for the video. Great find on the fault. I do think that I saw a bit of distortion and wobble on the scope trace, after the repair. You might want to look at that closer. Maybe a component that supports the amplifier component got stressed? HTH. Cheers.
Really enjoyed the tour of the museum Frank. It was fun to see all that stuff. I wish more people would visit museums like this to see how far we've come in media instead of just sitting in front of our computers or staring at our phones. Great video.
@@elmofeneken4364 Glad you liked it. If your ever in the Vancouver area. They're open Sundays year round.
How did you repair tuner band
@@raymondkuipers8669 There's a spring in there that tensions the string. I just tied the broken string a little shorter.
I thought, RCA was a true manufacturer. But it seems, it was only a sailsplatform for goods made by Asians. Radio Corporation of Armorica, lol
They did originally manufacture radios but this was probably such a cheap set it was more profitable to get a Japanese company to manufacture it as they had cheaper labor. Higher values items like TVs continued to be made by RCA until at least 1986 when they shut down their last USA Television plant.
RCA was an American manufacturer of many different kinds of electronics from the 1920s until they were bought out by GE in the 80s (existing in name only after that). Interestingly, an Asian offshoot was founded by RCA in the 1920s... the Japanese Victor Company, aka JVC. JVC, for obvious reasons, parted ways with RCA during WWII and has remained their own entity since then.

I like your trouble shooting methods. The way you explain things is clear and easy to understand. Nice job on the Zenith!
I'm glad you find them easy to follow.

Beautiful🌹 and🌹👍
it may have got hit with static electricity, as they were pretty fragile.
It came out of a transistor radio push pull audio stage so I figured it just died due to thermal runaway, but who knows.
I think the middle piece is the germanium crystal, and the outer two are the contacts onto it.
Interesting concept. My thought was that the ring was maybe the base which held the Germanium piece on place and the two wires were bonded onto the Germanium pice on each side. It would be interesting to have a look at the original Mullard engineering documents.
Thanks for that, very interesting.
Thanks. Tough to take these apart without destroying them.
Now make a crystal set radio out of it please 😉
To quote Dr. Leonard McCoy " I'm just a simple country doctor Jim, not a miracle worker."
@@FranksPlace-jk7pj You can do it ⚡️✊🏻🤠
As a schoolboy, I loved playing with OC71 and OC81 surplus transistors back in the 1970's... the bullet shaped glass OC71 was my favourite as you could scrape off the black paint and convert it into a phototransistor - which were much more expensive to buy ;)
The transistor came out of a Perdio transistor radio from about 1960 that was completely smashed and unrepairable.
telling me what youre going to do before you do it makes me feel impatient, instead.. you could show us first and say here ive done this and that.. just my 2 cents.. Cool content.
The white gunk used to be transparent gunk, and was replaced to stop people using the transistor as a photo transistor. Interesting to see this. Thank you. 😊
Thank You for your input.
@@beakytwitch7905Its like silicon caulking.
4 lead transistors became popular in the silicon days for RF & IF's It does go to GND. Remember changing many on RCA & Admiral IF's. BTW you should get strong stations without the RF amp & a lot of QRM unless its dead shorted. LFOD !
Yes, when I had the rf transistor out it did get strong stations. With it in, there is a lot of QRM but the sensitivity for a 1950s transistor radio is amazing.
I want to be there. I’m just sayin… ✨😳🎰
It was such a nice color I couldn't resist taking a shot of it.
Again. Wow....Frank. You are the master of the universe!

Burn your tongue..... Then burn your butt?
The leaky transistor may have tin whiskers inside. These are germanium, not the silicon variety we use today. Their bias is lower as well. 73 OM
Tin whiskers? I didn't know you could get them in Germanium transistors. Changing them out with those Japanese transistors sure improved the sound quality though.
@@FranksPlace-jk7pj On the AF output, you may have enough bias to put the silicon transistors into AB1 mode. This is usually regulated via a thermistor on the board. (I don't see one on the schematic in the video though.) I don't think you can replace any of the other germaniums though without gain loss. Germaniums are very sensitive to bias and can easily go into thermal runaway which is why the thermistor is there. It also has a very slow AGC affect in the audio because it is thermally controlled. The 4th wire on the OSC transistor (and RF amp if there is one) is a case GND. These are often the same transistors found in the Transoceanic series. There are some amazing pictures taken with an electron microscope of the insides of early germanium transistors showing the whiskers. Shango066 on YT has several amazing videos on the Zenith Transoceanic receivers. 🙂
This is the kind of radio with a special ballast tube. Philco number 33-3389. It was put into a special octal socket with two keyways, one for 115 V and the other for 230 V. I see the wiring diagram for the ballast tube on the schematic and looking at it is actually only used as a jumper for the connections for 125 Volts. It is needed for 230V when you place it in the right position for that voltage. If you have the ballast tube and it is dead check the ordinary wire connections in the base for continuity. Pins 2,3, and 7. Then you can redo the speaker next. But not this way, yikes. Rotten insulation on many wires to be replaced. And don't modify the chassis to fit a too large PM speaker!
My hope is to repair the speaker cone and put it back in the radio, as everything on the speaker assembly is good except the paper cone.
Very interesting radio. The transistor symbols on the schematics look strange. I newer saw these symbols before. The ГТ-309В transistor is a germanium one. The "ГТ" means "Германиевый Транзистор" (Germanium Transistor) in Russian. The silicon transistors are marked as "КТ" ("Кремниевый Транзистор" - Silicon Transistor). Thank you for the great video!
The Soviets must of switched to the international symbol for transistor later in the 70s when relations with the west were getting more relaxed.
The D in 500D stood for distance reception indicating the improved RF stage and featured their inverted cone speaker but was not put into all model of the 500D's for some strange reason. I think they ran out so if you have trouble you could replace it with a regular cone one if it is bad. If it says "long distance" on the outside you were more likely to get one with the inverted cone. On a vintage transistor radio the first thing to do is a visual inspection of the circuit board to first eliminate a no sound condition. Then go into it more. Chalk it up to a learning process for the future. Old PC boards were poorly made including traces. I learned some things here ( always good!) as I have a 500 that works but poorly. Thanks Frank! Steve
The radio works like gangbusters now and the sensitivity and tone is excellent. I can receive 5000 watt stations in the day from the nearest major city 150 miles away.
Most guys don't know this but the shaving cutter head and stationary blade cover are matched sets so don't interchange them or you will experience lower shaving quality for a week or two until they seat properly. They sent you the wrong set of replacements by the way. You need the SH30/52 and always request the manufacturer's sealed box and not just the sealed placard they come in. Some unscupulous sellers actually do that!
They sent me the blades with shaving cutter heads as you can see but I didn't have time to wait for new ones, hence the modification. Good to have the right part number for next time, thanks.
Very illustrative ty for the information
I also have never seen a speaker like that.
It seems to be only used in the 500D, the earlier 500's have a conventional speaker, I don't know if they used it again in any model after 1958.
This radio was made by Arvin.
I just purchased another one last week, (the green one of the series) and it works. Arvin smartened up and made a bigger battery compartment for this one as it takes a standard 9 volt battery.

In Soviet Union you didn't have radio, radio had you. Cool viddy!
Interesting.
That's a K-Mart Special, too. A new spark plug, a pump gasket, and new oil would be doing the most. Otherwise, just clean the mower deck, and spray with WD-40. Sharpen and balance the blade. Check wheels for wobble and nuts for tightness, along with the rest of the frame. Many of the mowers you see on the side of the road can be fixed so easy. Pump Gasket, or a varnished bowl, needle and seat. This is all before a rebuild, and 40 more years.
Gas stabil works too for storing away into the winter months
WD 40 is kinda both. Its a lubricate. But at the same time its flammable to start the lawn mower...
You should probably do that before you park it for the winter
Love those older Briggs and Stratton engines. Hard to kill.
Not a bad idea WD (Water Dispenser) Mineral oil lubricant. Also works great to clean fuel injectors. Try to find 'Non Ethanol' fuel for your mower and you will not have any issues especially after storing.
I was given one of these with no damage or missing parts and it's untouched. It was working they say. I don't like working on this type of assembly but I got to do it. I have a National shortwave I have to do too. I'm just spoiled from working on printed circuit boards.
I got to hook a digital frequency meter to the RF generator it is an old Heathkit tube RF generator but it still works great.
Good luck.
It's probably is a bit of both. It smokes for about two minutes after you start it but then blows clean exhaust.
WD 40, interesting. Does it act like a starting fluid or lubricate cylinder and piston rings, for that 1st startup?
It lubricates the cylinder, piston and rings from sitting dry all winter. It also helps the valves not stick in the valveguides.
